BMW i3 Concept

The BMW i3 Conception is an uncompromisingly sustainable fomite intentional for urban areas. Impelled strictly by wattage and purpose-made to adjoin the demands of sustainable and emission-free mobility, it embodies an thinking mannikin of urban transport and commutation.

“This self-propelling construct uses a new architecture which showcases all of its new possibilities and potency. It is the reality’s get-go bounty galvanizing fomite.” – Andreas Fice, Psyche of fomite labor BMW i3.

The BMW i3 is a well-resolved well-rounded conception, with every item conceived and optimised to meet its eventual use. Key to its figure is the modern LifeDrive architecture, the key to the BMW i3 Conception’s appealingness as a igniter, secure and wide car. Forward-looking use of materials and levelheaded whippersnapper pattern not but enable the i3 Construct to locomote hanker distances on a i bearing and ply brilliant condom in the outcome of a hit, they besides assist devote the car its first-class drive kinetics. The insure system of the bombardment in the Effort faculty gives the fomite a real low inwardness of graveness and optimal burthen dispersion. The electrical drive terminated the bottom axle – which generates yield of 125 kW/170 hp and telling torsion of 250 Nm (184 lb-ft) from a impasse – and a minor turn roach cartel to render pleasingly crease impulsive characteristics and commit the driver a really contiguous know of the BMW i3 Construct’s whippersnapper invention. The BMW i3 Conception accelerates from 0 to 60 km/h (37 mph) in nether iv seconds and from residue to 100 km/h (62 mph) in less than ogdoad seconds. The exceedingly orchestrate sentiency at the bike is verbalized in prominent lightsomeness at low speeds and during turn manoeuvres, and makes parking in slick situations that often easier.

The Sprightliness faculty conjures up a touch of spa indoors the car more generous than level the up-to-the-minute rebirth vehicles can fling. Prime materials add the outdoors and aeriform cabin a lounge-like fibre. The use of renewable raw materials is another shaping feature of the inside, oblation passengers a farther way of “experiencing” the sustainability of the fomite. Elements of the panel and threshold paneling are visibly made from rude fibres, piece the course bronzed leather of the seating creates a lounge-style atmosphere. Unitedly, these materials ply an likeable line to the crystalise, “vagrant” forms of the panel and doorway elements, and add the internal a strikingly forward-looking smell. With the effort components placed in the Effort faculty, thither is no center burrow linear done the rider compartment. This allows the two presence and two back seating to be machine-accessible with apiece early by a uninterrupted behind rise, which allows for repose of launching and expiration via the battlefront rider position of the car and way you can common up around walls, e.g.. With iv seating, wide-opening opponent “motorcoach” doors, kick capability of some 200 litres and an extra operative compartment in the movement, the BMW i3 Conception is neatly weaponed for the demands of unremarkable use.

Nevertheless, the galvanising drive highly-developed by BMW and the optimised whippersnapper innovation of the LifeDrive architecture cannot proceeds all the acknowledgment for imbuing the car with such efficiency and enabling it to jaunt such hanker distances on apiece commission. So, the power of the car to deduct vigor spell on the motion and peculiar range-extending functions, such as ECO PRO style, too add miles to the time. With ECO PRO manner excited, all the fomite functions manoeuvre with maximal efficiency. E.g., the gun function is tweaked to demarcation the yield summoned when the driver flexes his rightfield substructure, and the clime command functions besides use as lilliputian vim as potential. Added to which, advanced aeromechanics and thin, low peal resistor wheels downplay impedance to the car’s advancing procession and maximize its grasp.

Innovational connectivity functions make a unseamed association betwixt the BMW i3 Conception and its customers’ lives external the car. Distant functions approachable via a smartphone enable owners to incur their vehicles, pin up nearby charging stations, countenance bombardment charging and preconditioning at the hint of a clit and supplying data on the flow position of the fomite. Lag, levelheaded assist systems rest the strain on drivers in humdrum metropolis impulsive situations and countenance them to hit their goal more safely and in a more relaxed country of intellect.

The LifeDrive architecture

Both the BMW i3 Construct and the BMW i8 Concept suffer been intentional round the advanced LifeDrive architecture. Still, the geometrical effectuation of the conception differs in the two models, having been altered to courtship their dissimilar usages. The BMW i3 Conception features a horizontal-split variance of the LifeDrive construct optimised to fit the car’s galvanic effort organization. Hither, the Campaign faculty provides the unanimous foundations for the Aliveness cellphone, which is merely mounted on top. The impulsive ingredient of the Cause faculty’s operational excogitation is the barrage, which is made as expectant as potential to devote the car bettor ambit. Posture in judgment the sizing of the BMW i3 Construct’s barrage, the about space-efficient office to memory it was in the car’s underfloor part. Thither, it occupies the unit of the faculty’s cardinal department, handsome the car optimal burthen dispersion and a low gist of soberness and so enhancing its kinetics. The shelling is penned in by aluminum profiles, which protect it from international impacts. Crash-active structures ahead and arse it offer the requisite get-up-and-go preoccupation in the issue of a front- or rear-end hit. The galvanic driving scheme is, as a unscathed, often more compress than a corresponding burning locomotive, smartly accommodative the galvanizing drive, geartrain fabrication and crusade electronics – in space-saving style – inside a little ar o’er the goaded ass axle. The BMW i3 Conception consequently features the optimal LifeDrive architecture conformation for a strictly galvanizing fomite.

The build of the BMW i3 Conception is likewise idealistic for metropolis drive. Its enviably diminished turn roach and organise steerage responses are a formula for great lightsomeness, notably at low speeds. Rear-wheel ride allows the forepart axle to rest disengage from effort forces and thus to fulfill its guidance part to optimal burden. These elements team with the galvanizing motive – whose telling torsion from a stalemate provides exceeding grip – to farm exceedingly active manipulation characteristics.

The roomy Biography faculty of the BMW i3 Conception allows the fomite’s upcountry to gas a completely new invention. The desegregation of all the ride components inside the Ride faculty removes the want for a essence burrow bisecting the inner, done which might would antecedently birth been transferred to the bottom wheels. The BMW i3 Conception hence offers importantly more upcountry place than early vehicles with the like wheelbase and – done solutions such as a full-width arse workbench – besides allows the national to be altered passing efficaciously to the inevitably of urban mobility. Added to which, a couple of opponent doors and the deletion of B-pillars offer a prominent introduction expanse for passengers – and a generous scene into the with-it inner for admiring eyes. The BMW i3 Construct offers well-off fitting for iv passengers and, with about 200 litres of bang spa, way for their baggage also. Up movement, underneath what would ordinarily be the cowl, the Liveliness faculty gives the BMW i3 Conception a branch baggage country with blank for the charging cablegram and early items passengers would kinda not extend in the rider compartment.

All-electric

The galvanising motive of the BMW i3 Conception is intentional mainly for functioning in an urban surroundings. Already well-tried in a pre-production rendering in the BMW ActiveE, the reading of this permanently aroused intercrossed synchronal centrifugal which bequeath be victimized in the BMW i3 Conception has undergone boost optimization in footing of angle and driveability. It develops 125 kW/170 hp, with crest torsion of 250 Nm (184 lb-ft). Typically of an electrical centrifugal, uttermost torsion is highly-developed from stand, in line to an inner burning locomotive where torsion increases with locomotive rpm. This makes the BMW i3 Construct extremely quick and provides telling speedup. The BMW i3 Construct accomplishes 0-60 km/h (37 mph) in below quadruplet seconds and 0-100 km/h (62 mph) in nether eighter seconds.

Concurrently the abundant torsion is delivered concluded a real prominent rpm orbit, resulting in real shine mightiness speech. The single-speed gearbox provides optimum superpower transmittal to the backside wheels and accelerates the BMW i3 Construct to an electronically governed 150 km/h (93 mph) without the release of powerfulness typically associated with having to switching gears. The fastness regulator cuts in at this pointedness in the interests of efficiency: loss level quicker would outcome in really gamey muscularity uptake, which would unnecessarily bound the drive orbit. The motive is placed immediately supra the ride axle, for optimum and distinctive BMW rear-wheel-drive treatment characteristics.

But telling, instant, answer is not the lonesome classifiable panorama approximately the drive receive in the BMW i3 Construct. Another is the two-fold catalyst/decelerator procedure of the gun. Later the driver eases abreast the catalyst, the galvanic centrifugal acts as a source, converting the k.e. into electricity which is so fed rear into the barrage. Push convalescence generates a braking essence which makes a important part to fomite slowing. Approximately township, roughly 75 per penny of all braking operations can be performed therein way, i.e. without exploitation the bracken bike at all. Intensifier use of this muscularity convalescence office of the electrical centrifugal can addition the drive ambit by capable 20 per centime. Only the driver’s braking postulation exceeds a precondition degree is the established brakes of the BMW i3 Construct occupied too.

A coasting installation makes this alone “single-pedal mastery” of quickening and braking victimisation scarce the gun tied more user-friendly. The BMW i3 Conception features a distinguishable “electroneutral” situation of the accelerator, i.e. quite than switch straightaway to recovery when the driver eases off the bicycle, the electrical centrifugal’s aught torsion controller keeps the ride gearing disordered as yearn as the wheel is therein place. The fomite now coasts without overwhelming superpower, determined by its own k.e.. Secondhand as role of a proactive drive dash, this coasting mood is a identical user-friendly way of increasing the impulsive stove eventide boost.

Compact and powerful – the electric motor

The electrical motive of the BMW i3 Construct not sole offers attractive driveability, it too has a identical gamey power-to-size proportion. This is partially explained by the fact that electrical motors typically reach complete 90 per penny vigor efficiency. This way that a littler electrical drive can grow the like superpower turnout as a bigger intimate burning locomotive. Due to its compress sizing, the galvanic drive victimized in the BMW i3 Construct can be optimally incorporated into the fomite architecture. The permanently frantic cross synchronal galvanising motive and the exponent electronics of the BMW i3 Construct were highly-developed completely in-house, and gas identical highschool efficiency, optimised index livery and press invention. As mentioned, the advanced nature of the galvanising drive is peculiarly observable in the favorable power-to-size proportion. As a solvent of uninterrupted developing and elaboration, the quad requirements of the galvanizing centrifugal put-upon in the BMW i3 Construct let been rock-bottom by 40 per centime compared with the drive ill-used in the MINI E. This compact drive unit is mounted over the rear axle, together with the power electronics, transmission and differential, causing no loss of interior space.

The power needed to drive the vehicle and to operate all other vehicle functions is supplied by specially developed lithium-ion battery cells. The BMW i3 Concept’s battery system has undergone detailed optimisation which significantly reduces the extent to which external factors can influence the vehicle’s power and driving range. An integrated liquid cooling system keeps the battery at its optimal operating temperature at all times, which helps to significantly boost the performance and life expectancy of the cells. The climate/heating system cools the fluid circulating in the battery housing via a heat exchanger.

If necessary, in winter, this fluid can also be heated in order to bring the battery up to its optimal operating temperature of around 20 degrees Celsius. These precautions ensure that power and torque remain constant throughout most of the battery’s charge range and make the system significantly less sensitive to extreme external temperatures. The battery can be fully recharged in six hours at a standard power socket. If a high-speed charger is used, an 80 per cent charge can be achieved in just one hour.

Range Extender increases the driving range

As the MINI E field tests showed, a driving range of 120 to 150 kilometres (74 to 93 miles) was sufficient to meet 90 per cent of the mobility requirements of the pilot users. However, some customers want a longer driving range, or want their vehicle to be as flexible as possible. The BMW i3 Concept therefore offers an optional Range Extender, the REx, which allows the electric driving range to be increased. REx, a small, very smooth-running and quiet petrol engine, drives a generator which maintains the battery charge level and therefore extends the range of the electric motor. As soon as the battery charge reaches a critical level, REx supplies the necessary energy to get the driver the rest of the way to his destination. In a sense, therefore, the Range Extender is like having a reserve fuel can on board.

The very compact size of the electric motor used in the BMW i3 Concept means there is room left over to accommodate REx and its attached generator over the rear axle, alongside the drive components. The petrol engine complies with the SULEV standard, currently the strictest emissions standard for internal combustion engines. To reduce fuel consumption to a minimum, REx also features such functions as Automatic Start-Stop and other intelligent operating strategies.

BMW i3 Concept – compact, agile, sustainable

The design of the BMW i3 Concept reveals the car’s qualities the first time you set eyes on it. The BMW i3 Concept represents the dynamic interpretation of an impressively practical vehicle.

The proportions – dynamic, compact

Agile and compact proportions showcase the agility of the BMW i3 Concept and the dynamic prowess of its electric drive system. The stylistic lines within the car’s proportions provide additional emphasis here. From the side view, a number of elements combine to create a dynamic wedge shape, giving the car the feeling of pushing forward before it even turns a wheel. The generously-sized greenhouse tapers towards the rear and, together with the rearwards-rising door sills, emphasises the car’s dynamic inclinations. Above the greenhouse, the “stream flow” – a dynamic stroke descending from the roof into the C-pillar – adds further urgency to the forward-surging stance. From the outside, a flowing silhouette and long wheelbase hint at the extraordinarily generous levels of space on offer in the interior, while short front and rear overhangs make parking in tight spaces that much easier. Practicality gets another boost from the “coach doors”, whose opposing construction creates a fresh new way of accessing the wide-open spaces of the interior.

“The design reveals the driving pleasure on offer with electromobility. And you can add to that a large and practical interior.” – Benoit Jacob, Head of BMW i Design Team

Extensive glass surfaces and black elements like the window surrounds and door sills give the vehicle a feeling of lightness and, together with the exposed carbon structures, draw attention to its low weight. At the same time, the lack of B-pillars ensures a seamless transition between the two doors. The result is a large, homogeneous glass surface, which gives the car’s flanks a very transparent look. Large, narrow 19-inch wheels add further impact to the dynamic side profile of the BMW i3 Concept. Their slim construction allows them to reduce the car’s drag and rolling resistance, and to avoid encroaching into the interior. And that means more space for the passengers.

The striking front end

The front end of the BMW i3 Concept has a very clear and uncluttered design. The dominant element here is the strikingly moulded kidney grille, which has the hallmark BMW i blue background and – thanks to the car’s all-electric drive system – is totally blanked off. The grille also has a conspicuous swage line picking up from the bonnet edge. Below the kidney grille, the silver-coloured outer layer lends the sculptural front apron its form. The precise, vertical edges of the front apron element serve as the vehicle’s side borders and reinforce its powerful stance on the road. Black surfaces identify the functional areas of the front end, such as the load compartment under the bonnet and the air inlets.

The eye-catching LED headlights usher in a fresh take on BMW light design. Along with the strikingly formed kidney grille, the U-shaped LED-backlit lines form an important part of the arresting new BMW i face. The minimalist interpretation of the individual headlights underlines the efficiency and lightness of the BMW i3 Concept and lends it an individualist, outward-looking and reputable air.

The functional rear end

The rear end of the BMW i3 Concept represents a microcosm of the car’s impressive functionality overall. The large, retractable rear window offers optimum access to the luggage compartment, and the roof pillars stand upright to create as much space as possible in the interior. Its large glass area allows the rear window to offer unbeatable rear visibility. The rear window is also home to the tail lights, which are U-shaped (like the headlights) and appear to be floating in the glass. Behind it lies an extremely versatile boot area, whose capacity can be further increased by folding down the rear seats.

The wide, silver-coloured rear diffuser marks the body’s lowest edge and allows the driver to experience the car’s efficient aerodynamics. Bordered by a blue layer, the diffuser tapers heavily towards the road and appears to continue underneath the car. The form of the diffuser underlines the car’s powerful stance. A sportier version can be found on the BMW i8 Concept, forging a link between the two models.

Self-supporting and light – the interior

The version of the LifeDrive architecture that underlies the BMW i3 Concept opens up totally new avenues in interior design. Since the battery is located entirely in the underfloor section of the Drive module, the whole of the Life module is given over to the interior – a further benefit of purpose-built design. There is no centre tunnel bisecting the cabin, and the interior creates a very free, open and airy impression. At the same time, the design of the interior is extremely modern and clean: taut lines, powerful contours and small radii dominate the geometric forms on display. Here again, the Porcelain White support structure, black technical level and comfort section with Mocha Brown leather are split into separate layers.

The passengers sit in a raised position in the generously-sized Life module of the BMW i3 Concept. This semi-command position provides a good view over the hustle and bustle of city traffic and, at the same time, eases access to the seats. The full-width seat benches in the front and rear create a new and connecting feeling of space for the passengers in the light interior. With the benches stretching like bridges across the interior, passengers no longer sit strictly apart. This layout also allows them to swap from one side of the car to the other and, if necessary, to all climb out of the car comfortably on the same side. This represents a major boost to comfort in tight parking spaces and when access to one side of the parked car is impeded. The front seat bench features delicate-looking seat backrests marking out the driver and front passenger seats. The slim backrests are a faithful expression of the car’s systematic lightweight design and, at the same time, create more legroom for the rear passengers. The backrests are only connected with the seat bench towards the centre. At their outer edges they appear to be floating freely, which further underlines the airy character of the interior. Another special design element are the blue straps behind the seats, which run diagonally across the backrest and offer another functional stowage facility.

A distinctive element of the light interior is the freestanding steering column, around which all the other elements are grouped. Its pared-down surroundings leave the steering column to extend out prominently into the interior, while cut-outs in the column add to the airiness of the interior. All the driving-oriented controls – such as the instrument cluster, start/stop button and gearshift lever – can be found on the steering column. The gearshift lever takes the form of a rotary controller which can be moved forward or backward to select the desired driving mode – the car moves in the direction indicated by the controller. Positioning the controls on the steering column removes the need for a centre console in the BMW i3 Concept, and integrating the iDrive Controller into the seat bench eliminates this dividing element between the driver and front passenger. Another functional detail is the cupholder, which is integrated to the left of the driver in the air vent. This neat solution allows drinks to be kept warm in the winter and cooled by the climate control system in the summer.

Contrasts as a calculated design element

Taken as a whole, the interior – with its warmer colours – provides a pleasant contrast to the cool and technical air of the exterior. And there are many other contrasts to be found when you get down to the details. Behind the steering column the extremely intricate yet extensive instrument panel spans the interior.

2011 Bmw I3 Concept

It begins at the air vents next to the steering wheel, continues in a line around the steering column, includes the radio and climate controls, and continues on its path to the front passenger. Shortly before the front passenger door it then shears upwards, heads back towards the centre of the interior and reaches the end of its journey in the central information display (CID) monitor positioned above the control panel for the radio and climate system. Connectivity – the linking up of the driver and passengers with the outside world and information superhighway – plays an important role in the BMW i3 Concept, and is a theme given prominent treatment by the interior designers. For example, the instrument panel generates an almost calligraphic surface design around the displays, one large, wide surface sweeping prominently into a narrower and more delicate counterpart, before culminating in another wide section. The CID and control unit therefore present an attractive contrast to the clear, precise borders of the instrument panel.

The area around the instrument panel, the doors and the floor area of the BMW i3 Concept also features contrasting materials. The entire lower area of the BMW i3 Concept interior consists of renewable raw materials. The natural origins of the high-strength dark anthracite material made from compressed and coated plant fibres are clearly evident and showcase the light and beautifully crafted elements of the interior to optimum effect. The subtle background sets off individual elements such as the instrument panel and door pockets extremely effectively and, at the same time, underlines their function.

The dark Mocha Brown leather also provides a pleasant contrast with the Porcelain White support structures of the seat bench and instrument panel, and brings a homely lounge character into the vehicle. A large, light-grey wool felt floor mat with blue trim completes the warm and cosy feel. A further contrast to the transparent, pared-down design of the interior is provided by the support structure in the roof, whose organic, branched-out appearance recalls the myriad tentacles of a road network.

Interface design delivering intelligent mobility

In the BMW i3 Concept, three large displays act as interfaces between the vehicle, the outside world and the car’s occupants. These screens provide access to vehicle and environment-related information, such as the current driving conditions and battery charge, route guidance and nearest charging stations. The freestanding instrument cluster, meanwhile, emerges out of the steering column directly in front of the driver. With a 6.5-inch (16.5 cm) screen diagonal it displays all the relevant driving information in the driver’s field of vision. Its freestanding design generates a very free and open feel around and above the driver’s head. Meanwhile, the central 8.8-inch (22.4 cm) information display curves out of the black technical layer of the instrument panel’s upper section towards the passengers. It blends seamlessly into the black surrounds, creating a very high-quality, continuous black surface which makes the display appear even larger. Below, the likewise unbroken black audio/climate control panel shares the form of the central information display (CID). Like the CID, the homogeneous touch-control surface curves towards the passengers and uses another screen to show additional information relating to the content on the central information display.

On another level, the highly technical-looking display graphics of the instrument cluster and CID lend visual form to the BMW i3 Concept’s electric drive philosophy. All the information is displayed in the high quality and visually appealing fashion you would expect from BMW. Although the relationship of the i3 Concept to the parent brand is clearly evident again here, a very distinctive graphics profile has been created for BMW i with the emphasis on an individual and minimalist approach. All the displays are three-dimensional. The efficiency display, which takes the form of an open-topped ellipse, surrounds the digital speed screen in the centre of the instrument cluster. Its gauge tells the driver whether energy is currently being taken from the battery or supplied to it through recuperation. The driver can also find information here on the car’s remaining range and driving mode currently selected. If the driver switches to range-enhancing ECO PRO mode, the whole display concept also changes. The ellipse in the instrument cluster becomes flatter, the projected range increases and a display showing the optimum accelerator position for efficient driving completes the new format. The climate control panel also provides visual confirmation of the function-related changes in ECO PRO mode. The driver is therefore kept very effectively informed and given the best possible support in every driving mode.
