Walk into any busy car showroom and you will probably see a petrolhead opening the hood to see the engine under the hood. What are they really looking at? Do they even know what they are looking at or for? Well, this is the petrolheads fascination and we are here sharing some technical details of the new BMW 330i engine.
The engine in the new BMW 330i Sedan generates more spirited performance than ever. Boasting numerous detail upgrades, this two-litre, four-cylinder unit delivers maximum output of 190 kW/258 hp between 5,000 and 6,500 rpm, while peak torque of 400 Nm (295 lb-ft) is available from 1,550 to 4,400 rpm. The 5 kW/6 hp increase in output and the extra 50 Nm (37 lb-ft) of torque compared with the predecessor engine are the result of the focused optimisation of the BMW TwinPower Turbo system – which comprises twin-scroll turbochargers, 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 further developed direct injection system enables optimal fuel flow through the combustion chambers with atomised fuel delivered by multi-hole injectors. Other characteristics of this engine include a lighter crankshaft, reduced internal friction, optimised heat management and a new digital engine management system.
An impressive 0 to 100 km/h (62 mph) time of 5.8 seconds belies the enhanced efficiency of the new BMW 330i Sedan with its combined fuel consumption of 6.1 – 5.8 l/100 km (46.3 – 48.7 mpg imp) and CO2 figures between 139 und 132 grams per kilometre.
The engine’s emissions have also been further improved. The exhaust treatment system includes a particulate filter to reduce emissions of particulate matter. As a result, the new BMW 330i Sedan complies with the particularly demanding Euro 6d-TEMP emissions standard.
