Innovative engine technology on the top models.
The models right at the top also excel through outstanding efficiency ensured by innovative technology. The new BMW 335i Coupé and the new BMW 335i Convertible are entering the market with a newly developed straight-six power unit for the first time combining BMW TwinPower Turbo Technology, High Precision Injection, and VALVETRONIC fully variable valve management. Displacing 3.0 litres, the engine delivers maximum output of 225 kW/306 hp at 5,800 rpm, with peak torque of 400 Nm/295 lb-ft maintained all the way from 1,200 to 5,000 rpm.
The turbocharger system applying the TwinScroll principle with separate ducts for each set of three cylinders both in the exhaust manifold and in the turbocharger itself, and VALVETRONIC valve management now enhanced to an even higher standard, ensure a fascinating, direct response to the gas pedal at all times. Combining these features with High Precision Injection, the new power unit offers the muscle and performance of a naturally aspirated eight-cylinder with exceptionally low fuel consumption and exhaust emissions.
Acceleration from a standstill to 100 km/h comes in 5.5 seconds in the BMW 335i Coupé and in 5.8 seconds in the BMW 335i Convertible. Top speed is limited electronically on both models to 250 km/h or 155 mph.
Average fuel consumption in the EU test cycle is 8.4 litres/100 kilometres (equal to 33.6 mpg imp) on the Coupé and 8.8 litres (32.1 mpg imp) on the Convertible. The CO2 rating is 196 and, respectively, 205 grams per kilometre.
Efficiency and maximum power all in one: the BMW 335i featuring BMW TwinPower Turbo, High Precision Injection and VALVETRONIC for the first time.
The most powerful version of the BMW 3 Series likewise comes with an even higher level of efficiency in the 2010 model year: The new BMW 335i stands out in particular through the supreme muscle of its 225 kW/306 hp straight-six now combined more than ever before with a level of economy quite unique in this performance class. With power and performance remaining the same, average fuel consumption of the BMW 335i Saloon and the BMW 335i Touring is down compared to the previous models by approximately 8 per cent. This progress is attributable, among other things, to the introduction of a new generation of engines also in the BMW 335i. Indeed, the new power unit featured in the BMW 335i is the first engine to combine BMW TwinPower Turbo Technology both with High Precision Injection and fully variable VALVETRONIC valve management.
The new six-cylinder boasts a turbocharger system applying the TwinScroll principle to separate the ducts of three cylinders at a time both in the exhaust manifold and in the turbocharger itself. This particular configuration ensures a smooth and direct surge of power with immediate response even at low engine speeds, High Precision Injection interacting with newly developed multi-hole injectors positioned in the middle of the cylinder head between the valves and in the immediate vicinity of the spark plug for particularly precise dosage of fuel into the combustion chambers. To further optimise the development of power and the superior efficiency of the engine, fully variable VALVETRONIC valve management masterminds valve stroke and intake valve timing in an infinitely variable process. This reduces throttle losses in the charge cycle to a minimum and makes particularly efficient use of the energy in the fuel. And last but certainly not least, engine response is also even better, more dynamic and smoother than before.
The engine delivers its maximum torque of 400 Nm/295 lb-ft all the way from 1,200 – 5,000 rpm, and reaches its maximum output at 5,800 rpm. This accelerates the new BMW 335i Saloon from a standstill to 100 km/h in just 5.6 seconds (Touring: 5.7 seconds). Top speed is limited electronically to 250 km/h or 155 mph. Perhaps the most impressive point is that both models combine this sports car performance with a further reduction of both fuel consumption and emissions, with fuel consumption in the EU test cycle of just 8.4 litres/100 kilometres (33.6 mpg imp) on the Saloon and 8.5 litres/100 km (33.2 mpg imp) on the Touring, plus a CO2 rating of 196 grams per kilometre (Touring: 199 grams).
