BMW 330i: more power and torque

Boasting numerous detail upgrades, the new 2.0-liter, inline 4-cylinder powering the new 2020 BMW 330i unit delivers 255 hp between 5,000 and 6,500 rpm and a peak torque of 295 lb-ft from 1,550 to 4,400 rpm. The 7 hp increase in output and the extra 37 lb-ft of torque compared with the predecessor engine are the result of the focused optimization of the BMW TwinPower Turbo system - which is made up a twin-scroll turbocharger, High Precision Injection direct petrol injection, VALVETRONIC fully variable valve timing and Double-VANOS variable camshaft timing. The High Precision Injection system ensures precise fuel metering and particularly clean combustion, its new fuel pump generating maximum pressure of 350 bar compared with the 200 bar of the previous version. The improved direct injection system enables optimal fuel flow through the combustion chambers with atomized fuel delivered by multi-hole injectors. Other characteristics of this engine include a lighter crankshaft, reduced internal friction, optimized heat management and a new digital engine management system. An impressive 0 to 60 mph time of 5.6 seconds belies the enhanced efficiency of the new BMW 330i Sedan.

The new BMW 330i and 330i xDrive Sedans are equipped with the 8-speed Sport Steptronic transmission as standard. The latest upgrade of this sport automatic transmission sees a wider gear spread (from 7.8 to 8.2 and also increases internal efficiency and improves vibration suppression. There is a new control unit and further enhanced gearshift dynamics. In addition to the optimized hydraulic control system, the shorter gearing for the lower ratios boosts the acceleration capability of the new BMW 3 Series Sedan. The 8HP 8-speed Sport Steptronic transmission delivers even shorter shift times and a Launch Control function for highly dynamic, traction optimized acceleration off the line than previous versions. Shift paddles on the steering wheel allow manual gear selection.

Intelligent connectivity enables the sport automatic transmission to adapt its shift strategy according to the route and driving situation. With the optional Navigation system, the 8-speed Sport Steptronic transmission uses data from this system and from the Active Cruise Control system’s radar sensor. This makes it possible for the transmission to avoid unnecessary gear changes when negotiating a series of fast corners and, when approaching a vehicle ahead, for example, to shift down early in order to use the engine braking to scrub off speed.

The Auto Start Stop function and the coasting function available in conjunction with the 8speed Steptronic transmission in the new BMW 3 Series Sedan also use data supplied by the optional navigation system with data from the standard Active Guard driving assistance systems’ front camera. In this way, inefficient engine shutdown - for example when stopping briefly at junctions or roundabouts - can be prevented. Movement of vehicles ahead is registered in order to determine the ideal moment for the Auto Start Stop function to stop and start the engine. The coasting function is now available when either ECO Pro or COMFORT mode is selected using the Driving Experience Control switch between 9 and 99 mph. The efficiency-enhancing decoupling of the powertrain only takes place in driving situations where performance and comfort are not compromised. If the driver suddenly lifts off the accelerator, the powertrain stays connected so that engine braking can be used to support deceleration. For the same reason, powertrain disconnection is also prevented when approaching a junction or a vehicle ahead.
