The new unit is based on the one in the 1.6-litre Mini Cooper S, with twin-scroll turbocharger, direct fuel-injection and variable valve control. The turbocharger is tweaked for extra boost and the engine has been fitted with a new high-performance exhaust system – finished with twin stainless-steel tailpipes.
Engine outputs are 155kW of power at 6000rpm, and 260Nm of torque from 1850-5500rpm, with 280Nm available for a few seconds on overboost between 2000-5200rpm.
It will be mated to a six-speed manual transmission as standard, but there will still be the option of a six-speed automatic with a manumatic mode and shift paddles mounted on the steering wheel.
Mini says the new engine gets a weight-saving aluminium block and bearing mounts, lighter crankshaft, reinforced pistons and a high-strength cylinder head.
The manual transmission gets a fuel saving stop-start system, and the load on the electrical system is reduced by brake energy recapture with the alternator disengaging at high revs – combining to cut your fuel burn by about 500ml per 100km.
