The BMW i3 has two pedals like all cars with automatic transmission. The accelerator pedal acts as both accelerator and engine brake. When the driver releases the pedal, the vehicle’s kinetic energy is regenerated by the vehicle drivetrain to recharge the battery. This has the effect of slowing the car down. During the field testing of the Mini E, which has an accelerator that recharges the battery in this way, and consists of brakes that only apply to the rear wheels, BMW has learned that drivers tend to rely on the engine brake: around 75% of all deceleration maneuvers are initiated without the brake pedal in urban traffic areas. BMW also expected the i3 to use the same type of battery and powertrain that is being tested in the BMW ActiveE trials.
The prototype presented at the 2011 International Motor Show Germany had a 22 kWh (79 MJ) lithium-ion battery pack that is expected to deliver between 130 to 160 km (80 to 100 mi) and the battery was fully charged in about four hours with the 240-volt charging unit. The i3 was expected to go from 0 to 100 km/h (0 to 62 mph) in less than 8 seconds. The BMW i3 has a 130 kW (170 hp) electric motor mounted on the rear axle to drive the rear wheels and the top speed is limited to 150 km/h (93 mph). nissan wallpapers, lamborghini, mazda wallpapers, BMW i3 wallpapers, lexus wallpapers
(Nissan Silvia)S13 Silvias were initially powered by the CA18DE and CA18DET engines carried over from the end of S12 production, with an intercooler added to the CA18DET for a slight increase in stability and power. In mid-1990, (for the 1991 model year) the SR20DE and SR20DET engines debuted, offering improvements across the board in power and torque due to increased displacement and a more efficient turbocharger than was offered on the previous cars. One of the other simple changes that were made between the CA generation and the SR generation was the switch to a single colour paint job, instead of the two-tone colour sets that were previously offered. On top of this, the SR motor later debuted another variant of the platform known simply as the “blacktop”. Identifiable by its black and silver rocker-cover (as opposed to the traditional red/silver cover), it featured a number of minor changes, resulting in a little performance gain. It is vastly different from the more powerful “notch top” used in the S14 and S15 variants. Nissan Silvia wallpapers#bentley #McLaren #RollsRoyce #BugattiDivo #AudiRS3
