1. Highlights: The All-New BMW i3:
The brand new all-electrical BMW i3 is a landmark in BMW’s mission to offer a totally sustainable, electrical car that also stays true to the Final Driving Machine moniker. The BMW i3 is the primary product of the brand new BMW i sub-model, and is a very objective constructed electrical automotive. It is a new period for electro mobility at BMW.
The car idea behind the BMW i3 was designed from the outset to include an all-electrical drive system. This has quite a few benefits over “conversion” automobiles, by which the unique combustion engine is swapped for an electrical motor. The engineers can design no matter works greatest, when it comes to development, dimensions and configuration of the electrical drive system’s elements. The automotive’s improvement is dictated by the traits designed into the automotive by the event staff and never by the constraints imposed by a pre-present car design. For instance, the area in a conversion car put aside for the gasoline tank or exhaust system can’t be used. Within the BMW i3 there isn’t a want for this type of compromise.
This results in the LifeDrive structure idea, which was objective-constructed particularly for the BMW i3. It’s comprised of two modules; the Life Module, and the Drive Module. Consider the Life Module because the passenger cabin, or greenhouse. It’s the first-ever mass produced Carbon Fiber Strengthened Plastic (CFRP) passenger cell within the automotive enterprise, and is an enormous issue within the automobiles effectivity. Carbon Fiber Strengthened Plastic is equally as robust as metal, whereas being 50% lighter, and 30% lighter than aluminum. The result’s an electrical automotive that weighs about 2,seven hundred lbs (preliminary US figures).
Because of the light-weight, excessive tensile power of CFRP, the passenger cell has added safety, and the battery has much less work to do, which permits for using a smaller, lighter battery that saves much more weight, reduces charging time and will increase vary. The sunshine weight design of the Life Module additionally lowers the BMW i3’s middle of gravity, making it a extra partaking and dynamic automotive to drive.
The Drive Module, which is constructed out of one hundred% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electrical drive practice, MacPherson strut and 5-hyperlink rear suspension system and structural and crash elements. The battery mounted within the rear, near the drive wheels, provides spectacular efficiency traits whereas additionally offering higher traction.
One other advantage of the LifeDrive structure idea is that there isn’t a area-consuming transmission tunnel operating by means of the middle of the automotive, like in most inner combustion powered automobiles, due to the separate Drive Module. This provides the BMW i3 the inside area of the BMW three Collection, whereas solely having the footprint of the a lot smaller BMW 1 Collection.
Even the car’s key’s sustainably manufactured. The supply materials of the brand new bio-polymer key’s based mostly on castor oil pressed from castor seeds. The proprietor’s guide can also be produced from renewable assets.
The inside is made utilizing top quality renewable sources and recycled supplies. The BMW i3 has the Subsequent Premium inside, which blends sustainable assets with a premium really feel for a similar inside high quality because the BMW 5 Collection Sedan. 25% of the plastics within the inside and 25% of the thermoplastic elements on the outside are produced from both recycled supplies or renewable sources.
Based on research carried out as a part of BMW’s Venture i, involving greater than 1,000 members and carried out over some 12.5 million miles, it was revealed that the typical day by day distance coated was round 30 miles. The BMW i3 will be capable of journey eighty to one hundred miles on a single cost. This may be elevated by as much as roughly 12% in ECO PRO mode and by the identical quantity once more in ECO PRO+ mode. It is ready to recharge in solely three hours with using a 220V Degree 2, 32-amp J1772 charger. The SAE DC Combo Quick Charging, which fees the BMW i3 as much as eighty% in 20 minutes, and one hundred% in 30, could be had as an choice.
With a purpose to scale back vary nervousness, a rear-mounted 650cc, 34 hp, two-cylinder, gasoline-powered Vary Extender generator is out there, which roughly doubles the car’s vary. When the battery will get to a sure degree, the Vary Extender begins and maintains the battery’s present state of cost. The Vary Extender by no means immediately drives the car’s wheels. The Vary Extender provides roughly 330 lbs. to the car curb weight and has a gasoline capability of two.four gallons.
Since 1999 in line with the DOE, common gasoline costs in America have elevated from roughly $1.136 to $three.618, or a few 218%. In the identical time, the pricing of electrical energy has elevated from 6.6 cents to 9.9 cents, a change of solely 50%, making electrical energy a much more engaging commodity from a pricing standpoint.

2. The Final Drive Machine®.
BMW makes the Final Driving Machine, and that holds true for the BMW i3. The hybrid synchronous electrical motor, which weighs solely one hundred ten lbs., is developed and produced specifically by the BMW Group to be used within the BMW i3, with most revs of eleven,four hundred rpm, generates an output of one hundred seventy hp and outputs most torque of 184 lb-ft on faucet from the second the automotive pulls away. That is propels the two,seven hundred lb automotive from zero-30mph in three.5 seconds, zero-60mph in roughly 7.2 seconds, and to an electronically restricted prime velocity of ninety three mph (preliminary USA figures). Very similar to engine braking with a guide transmission, however much more efficient, the accelerator pedal additionally acts as a brake when the driving force lifts off the accelerator.
The BMW i3 options Brake Power Regeneration, which, when the driving force lifts off, the motor acts as a generator and converts the kinetic power into electrical energy, which is fed again into the battery for a variety achieve. This Regeneration is velocity-delicate, which signifies that the automotive “coasts” for added effectivity at excessive speeds, and generates the robust braking impact at decrease speeds.
The BMW i3’s accelerator pedal has a definite “impartial” place. Fairly than switching straight to power Regeneration when the driving force eases off the accelerator, the electrical motor makes use of zero torque management to separate from the drivetrain and deploy solely the out there kinetic power for propulsion. On this mode, the BMW i3 cruises utilizing nearly no power in any respect. That is one other method anticipatory driving can protect power and improve the automotive’s vary.
The spectacular electrical motor, small turning circle of 32.three ft, – a serious profit to driving within the metropolis – BMW’s close to-good 50-50 weight distribution, exact electrical energy steering and the secure suspension set-up assist to make the i3 as satisfying to drive as each different BMW.
The BMW i3’s tires are a singular one hundred fifty five/70/19 measurement on 19-inch mild-alloy wheels, however the contact patch is identical of that of a extra typical sixteen-inch tire. To enhance effectivity, they’ve low rolling resistance, and the slender part width is a key issue within the BMW i3’s tremendous-tight turning radius.
The BMW i3 makes use of the BMW eDrive rear-wheel drive powertrain beforehand discovered on the BMW ActiveE. eDrive gives driving dynamics worthy of the Final Driving Machine identify and presents zero tailpipe emission driving. Past the normal immediacy of response provided by electrical motors when pulling away, energy improvement within the BMW i3 additionally stays unbroken by means of larger speeds. Energy is shipped to the rear wheels via a single-velocity transmission, permitting the BMW i3 to speed up with an uninterrupted move of energy as much as its prime velocity.
three. Metropolis Pleasant: The Way forward for City Mobility.
The BMW i3 marks the introduction of a brand new sort of megacity car. Its small measurement permits it to simply maneuver and park on metropolis streets, whereas the automotive’s brief entrance and rear overhangs make parking in tight areas a lot simpler. Its sharp turning radius and nimble dealing with are the right match for metropolis driving. Within the entrance, the Slide By means of Expertise permits the driving force to slip by way of the automotive and exit on the passenger aspect, to keep away from exiting right into a busy metropolis road. That is made potential due to the absence of the transmission tunnel. The coach doorways make stepping into and out of the automotive rather more sensible by eliminating the B pillar and creating one giant opening to enter and exit.
Not having to refill on fuel is an enormous benefit whereas dwelling within the metropolis because of the lack of fuel stations. Since electrical energy is so available, recharging is feasible virtually anyplace, and virtually provides the BMW i3 limitless vary resulting from with the ability to cost at any and each cease.
Emission-free driving can also be a plus within the metropolis. Cities are so congested with automobiles idling at pink lights or cease and go visitors, so having a automotive that runs on electrical energy that does not pollute is one other method that the BMW i3 advantages the setting, and its proprietor.
On an identical notice, the navigation system can take visitors circumstances into consideration and assist route round any areas of huge congestion, which is a large profit when dwelling in a metropolis with a variety of visitors. It may assist maximize effectivity and reduce down commute occasions as a way to prevent time.
The identical navigation system additionally remembers the house owners driving type and may decide by that and the quantity of cost left if a route is just too lengthy or if a recharge is important for the return journey.
four. Design: Aesthetic Attraction with Elegant, Renewable Inside.
The BMW i3 is stretching the definitive envelope of what a standard automotive could be and the way it ought to look. Its hanging look is exclusive to the BMW i sub-model whereas nonetheless remaining unmistakably a BMW.
The entrance finish has a transparent and easy design. BMW’s iconic kidney grilles headlines the entrance finish with the BMW i blue background. Underneath the kidney grille, silver layers sculpt the entrance apron. Contrasting black surfaces determine the useful load compartment underneath the hood and air inlets. Aerodynamic Air Curtains give an aggressive look to the BMW i3, whereas additionally serving to to extend the vary by minimizing air resistance and drag. U-formed, LED headlights, give a recent tackle the BMW mild design and provides the automotive character.
On the rear finish, the massive rear window provides nice visibility and quick access to the trunk. The roof strains are optimized to offer as a lot inside area as potential. The LED U-formed taillights are housed within the rear window and look like floating there.

Additionally, the excessive composite rigidity of the magnesium supporting construction permits a discount in elements and lowers weight by an extra 10%.
The wooden trim used within the dashboard is crafted from eucalyptus which is grown in Europe and authorized as one hundred% sourced from accountable forestry. Because the eucalyptus ages, it darkens and modifications colour. The situation of the crafting was chosen rigorously to make sure brief supply routes to the manufacturing levels.
The Carbon Fiber Strengthened Plastic (CFRP), which is produced close to Moses Lake, Washington, is made primarily with using hydroelectric energy, harvested close by. That is carried out to attenuate the impact that BMW i3 manufacturing has on the surroundings. Since greater than 10% of the carbon fiber wanted to fabricate the BMW i3 is comprised of recycled supplies, it’s one other approach the BMW i3 is totally sustainable. The roof is manufactured from CFRP scraps to assist recycle left over materials from different elements.
5. Discover the World: Car Trim Ranges.

eight. Security: All the time a real BMW.
From an effectivity standpoint, the physique of the BMW i3 must be not solely robust however, above all, mild. Nevertheless, from a security perspective, it needs to be not solely mild however, above all, robust. This obvious battle of pursuits highlights the engineers’ pioneering work in creating the car structure of the BMW i3. Right here, there isn’t a contradiction between light-weight development and security. Fairly the other, in reality: the LifeDrive idea of the BMW i3, with its mixture of aluminum and carbon-fiber-strengthened plastic (CFRP), is on a par with different buildings and even performs higher in some areas of crash testing regardless of its light-weight design. Using CFRP primarily permits the development of extraordinarily light-weight our bodies. Furthermore, CFRP possesses a powerful capability to soak up power and is extraordinarily injury-tolerant. CFRP is the lightest materials that can be utilized within the development of automotive our bodies with out compromising on security.
The LifeDrive idea is predicated round two horizontally separate unbiased modules. The Drive module – the aluminum chassis – provides the automotive its excessive-power foundations and integrates the battery and drive system right into a single construction. The Life module, in the meantime, consists principally of a excessive-power and very light-weight passenger compartment comprised of CFRP. With this progressive idea, the BMW Group takes the mixture of light-weight design, car structure and crash security to a completely new dimension.
LifeDrive module provides large security.
The crash necessities in automotive manufacture are very strict. Quite a few impression standards stipulated by the stringent tips of worldwide shopper safety organizations and legislators should be taken under consideration. In the course of the improvement of the BMW i3 idea, there was shut session with the worldwide crash check institutes on the revolutionary automotive physique and security idea of the BMW i fashions.
The excessive-power passenger compartment groups up with the clever distribution of forces inside the LifeDrive module to offer the cornerstones for optimum occupant safety. Even after the structurally-debilitating offset entrance crash at sixty four km/h (forty mph), the extraordinarily inflexible materials maintains an intact survival area for passengers. The crash-activated aluminum buildings on the entrance and rear finish of the Drive module present further security, in order that much less physique deformation happens in contrast with comparable metal our bodies. Moreover, the “cocoon impact” of the CFRP automotive physique ensures that the doorways may be opened with none drawback and the inside stays largely freed from any intrusions.
Even rescue situations have been labored by means of and checked. In normal slicing exams, the method of rescuing occupants from a BMW i3 concerned in an accident was similar to that for a standard car. In some respects, certainly, it was extra simple because the lighter elements might be extra simply minimize than excessive-power steels, for instance.
Spectacular rigidity, mixed with its potential to soak up an unlimited quantity of power, makes CFRP extraordinarily injury-tolerant. Even at excessive influence speeds it shows barely any deformation. As in a Formulation One cockpit, this exceptionally stiff materials supplies a particularly robust survival area. Moreover, the physique stays intact in a entrance or rear-on impression, and the doorways nonetheless open with no drawback after a crash.
In its dry, resin-free state CFRP could be labored virtually like a textile, and as such permits a excessive diploma of flexibility in how it’s formed. The composite solely good points its inflexible, last type after the resin injected into the lattice has hardened. This makes it at the very least as sturdy as metal, however it’s far more light-weight.
The excessive tear resistance alongside the size of the fibers additionally permits CFRP elements to be given a excessive-power design by following their path of loading. To this finish, the fibers are organized inside the element in response to their load traits. By overlaying the fiber alignment, elements may also be strengthened towards load in a number of totally different instructions. On this method, the elements may be given a considerably extra environment friendly and efficient design than is feasible with some other materials that’s equally sturdy in all instructions – akin to metallic. This, in flip, permits additional reductions when it comes to each materials use and weight, main to a different new wave of financial savings potential. The decrease accelerated mass within the occasion of a crash signifies that power-absorbing buildings may be scaled again, slicing the load of the car.
Superior safety in a aspect influence.
The power of CFRP to soak up power is actually extraordinary. Pole impacts and aspect-on collisions each spotlight the spectacular security-enhancing properties of CFRP. Regardless of the heavy, in some instances concentrated forces, the fabric barely sustains a dent, and passengers take pleasure in almost unbeatable safety. All of which makes CFRP completely fitted to use in a car’s flanks, the place each centimeter of undamaged inside is invaluable. Nevertheless, there are limits to what CFRP can endure. If the forces utilized transcend the bounds of the fabric’s power, the composite of fibers breaks up into its particular person elements in a managed course of.
Within the Euro NCAP aspect influence check, through which a pole strikes the aspect of the car lifeless-middle at 32 km/h (20 mph), the carbon fiber composite additionally demonstrates its extraordinary power-absorbing capability. The Life module absorbs the whole impression with minimal deformation, guaranteeing optimum passenger safety. Whilst CFRP dissipates power, hazard to passengers or different street customers is considerably mitigated.
The most effective of each worlds: combining aluminum and CFRP.
The brand new Drive module has additionally been rigorously designed and structured with these exacting crash necessities in thoughts. Crash-lively aluminum buildings within the entrance and rear sections of the car present further security. In a entrance or rear-on collision, these take up a big proportion of the power generated. The battery, in the meantime, is mounted within the underbody part of the automotive to offer it the absolute best diploma of safety. Statistically, that is the world that absorbs the least power within the occasion of a crash, and the car exhibits barely any deformation right here consequently. Furthermore, positioning the battery within the underbody permits the BMW Group improvement engineers to provide the car a great low middle of gravity, which makes it extraordinarily agile and unlikely to roll over.
The excessive-voltage battery additionally advantages from the superb deformation properties of the CFRP Life module. Within the aspect crash check, the pole doesn’t penetrate so far as the battery. The combination of supplies used and the clever energy distribution within the LifeDrive module make sure that the excessive-voltage battery is optimally protected even within the aspect sill space.
All in all, the excessive-power CFRP passenger cell groups up with the clever distribution of forces within the LifeDrive module to put the foundations for optimum occupant safety.
Within the unlucky state of affairs when an accident happens, Clever Emergency Name (“eCall”) sends info like location, variety of entrance-seat occupants, and even crash severity knowledge to the BMW ConnectedDrive Name Middle, which shortly informs the suitable 911-dispatch middle.
Lithium-ion batteries are protected even within the occasion of a fireplace.
Security is a key criterion within the improvement of the BMW i fashions. A variety of techniques and measures have been carried out within the car that guarantee security in regular operation and within the occasion of unintentional fires. The excessive-voltage system is designed to deal with accidents past the authorized necessities, with the excessive-voltage battery together with options that guarantee its protected response even in conditions similar to this.
The newest collection of checks carried out by the famend DEKRA E-Mobility Competence Middle have been extraordinarily in depth – starting from how a automotive may catch hearth, how the flames may unfold and what can be required to extinguish the hearth, to the air pollution brought on by run-off of the water used for preventing the hearth. The specialists concluded that electrical and hybrid automobiles with lithium-ion drive system batteries are no less than as protected as automobiles with typical drive techniques within the occasion of fireside.
To make sure most security in such a crash state of affairs, the excessive-voltage battery is disconnected from the excessive-voltage system and the related elements discharged when the passenger restraint techniques are triggered. This safely prevents the potential for a brief circuit, which might result in electrical shocks or trigger a fireplace.
The all-new BMW i3 might be featured on the Los Angeles Worldwide Auto Present in November, 2013 and can arrive at BMW i facilities within the US starting within the second quarter of 2014.
