TURBO JARGON: It may say ‘Twin Power’ but BMW’s new two-litre engine is actually a single-turbo unit statistically superior to its naturally aspirated sibling in every way.
BMW’s revealed its first four-cylinder forced induction petrol engine in decades.
The company’s latest TwinPower N52 engine is a two-litre four-cylinder with oversquare internal architecture (90.1mm bore x 84mm stroke) and a single turbo spun by twin-scroll exhaust plumbing.
It produces 180kW at an engine speed of 5000rpm and 350Nm at only 1250rpm - so it's powerful and efficient, thanks to the presence of dual-VANOS camshaft control and Valvetronic individual valve-lift technology.
BASED ON ONE OF THE BEST
This new turboed engine is essentially a truncated version of the three-litre N55 single-turbo six-cylinder engine which has started to replace the award-winning N54 twin-turbo six throughout BMW’s range.
The N52 will bear ‘28i’ badging when deployed across BMW’s product portfolio. Its first application will be in the X1, as xDrive28i.
BMW claims the new engine returns a combined consumption figure of 7.9 litres/100km in the company’s entry level SUV but still gives a stirring performance that's underscored by a 0-100km/h sprint time of only 6.1sec.
The brand's new range of forced-induction petrol engines (once a concept not even up for discussion at BMW HQ) has prioritised twin-scroll/single turbo tech as the most efficient way to re-route exhaust gas to drive turbine-boosted air-intake pressures.
Initially BMW's return to petrol-engine turbocharging was courtesy of the company's award-winning N54 engine introduced in back in 2006 with two turbo. This engine has been usurped by a single-turbo update, the N55, signaling that Munich's engineers have found one turbine to be quite sufficient, thank you...
