BMW North America is presenting two performance packages for the 135i Coupe and 335i vehicles. The brand’s slogan “power to the people!” refers to the two power levels that it is offering. The stage 1 Power Kit comes with an ECU remap that boosts power by 20 hp to 320 hp and raises the torque from 300 (406 Nm) to 332 lb-ft (450 Nm) for the auto transmission models. Meanwhile, the manual or DCT gearbox versions will have their torque raised to 317 lb-ft (429 Nm).
This kit is available as well for the X6 built until April 2010. BMW asserts that the 335i could accelerate from 0 to 60 mph faster by 0.2 seconds and cut its 50 (80 km/h) to 75 (120 km/h) mph sprint time by half a second.
It also results to a more visceral exhaust note during engine overrun. What the stage 2 Power Kit offers are improved engine cooling due to an extra water cooler and a new radiator fan that are only available on the 135i and 335i.
These two kits have lower launch prices until the end of 2011. The stage 1 Power Kit is priced at $599 and stage 2 Power Kit is available for $1,199 (excluding installation costs). The kits are offered with h BMW North America’s limited warranty and may be retrofitted with the use of the Port Installation Program or at BMW centers.
Power from the engines of both the BMW 135i Coupe and the BMW 135i Convertible will be transmitted to the wheels, as standard, through a new six-speed manual gearbox that has been optimized for maximum efficiency.
This new manual transmission features dry sump lubrication that could reduce drag forces and prevent splash losses – which result to a whole new level of efficiency. Also available for the BMW 1-Series is a seven-speed double-clutch gearbox with Sport Automatic, which further optimizes the car’s driving characteristics. Thanks to this newly developed double-clutch gearbox, both the BMW 135i Coupe and the BMW 135i Convertible boast of better acceleration and greater efficiency, featuring the comfort features of an automatic transmission from BMW.
This double-clutch gearbox – which could be employed manually or automatically -- features smooth and seamless gears-shifting sans any interruption of power and torque. This smooth, seamless and fast gear-shifting typically allows for suave acceleration, lower fuel consumption and lesser emissions. Since its seven gears feature close, sporting increments, the gearbox’s optimum transmission ratio could be accessed any time.
This gearbox also combines dry sump and injection lubrication in order to increase the efficiency of the engine by providing a steady supply of oil. Drivers could easily control the double-clutch gearbox through the gearshift paddles mounted on the steering wheel or via the newly designed gear selector lever.
By mating the new six-cylinder engine – featuring BMW TwinPower Turbo Technology -- and the seven-speed double-clutch transmission, both the BMW 135i Coupe and the BMW 135i Convertible are able become at par with powerful sports cars while providing the agility and driving experience typical of a BMW 1-Series.
