New petrol engines with more power and efficiency.

A new and improved version of the MINI petrol engine will be fitted to all First, One, Cooper and Cooper S models in the Hatch, Convertible and Clubman ranges. 

The MINI First and One models will now be fitted with a 1.6 litre engine, replacing the 1.4, and VALVETRONIC valve operation that delivers more torque and better fuel consumption.  All MINI petrol-engined models will conform to European EU5 emissions standards or ULEV 11 in the USA.

VALVETRONIC variable valve timing delivers a five per cent improvement on its own while an on- demand, map-controlled oil pump achieves a further 2.5 per cent fuel saving.  An improved, low friction engine vacuum pump accounts for another one per cent and a map-regulated water pump working on a pulsed cycle (rather than simply on or off) saves 1.2 per cent fuel.

Reduced friction from polished camshaft and main bearings, improved heat management and the specific features above combine to contribute more efficient use of energy by the new MINI range.

The fuel consumption improvements have been made despite the fact that the testing procedures under EU5 reduce certified gains. 

MINI First - The entry level MINI, MINI First, receives a new version of the 1.6 litre four cylinder engine that produces 75 hp, the same as its predecessor. 

 MINI One - The new engine enables MINI One to increase both power (by three per cent to 98hp) and torque (by nine per cent to 153 Nm at 3,000 rpm). 

MINI One Clubman - The MINI One Clubman benefits from the same powertrain improvements and offers 0-62 mph in 11.1seconds and a top speed of 115 mph.
