| “A
great example of a small engine with huge potential and ideally
suited to the cars it powers”

If proof were ever needed that engine collaboration
between automotive manufacturers can succeed,
BMW’s powertrain partnership with PSA Peugeot Citroën
is a perfect example, spawning the award-winning 1.6-litre turbo
unit.
Winner of the same International Engine of the Year Awards category
in 2007, when it narrowly beat the 1.5-litre Toyota Prius, BMW
and PSA’s four-cylinder has dominated the class this year,
collecting 136 more points than its closest rival, the 1.8-litre
TFSI Audi engine that powers a plethora of VW Group products.
Riding high on the growing trend of combining power with downsized
powertrains, the 1,598cc unit had plenty of judges waxing lyrical,
including Nikos Kounitis from Greece’s 4Wheels magazine,
who commented that he thought the motor represented “downsizing
at its best”. Dan Vardie from Romania’s Autoshow
added, “This is one of the first small engines able to
deliver performance normally found in bigger engines. Two engine
experts combine to create a robust, powerful and efficient petrol
engine.”
Constructed from light alloy, the heart of the Mini Cooper S,
Peugeot 207 and 308 features a twin-scroll turbocharger, gasoline
direct injection, twin overhead camshafts, roller-type drag
arms that have been optimised for minimum friction, and hydraulic
valve play compensation elements. Furthermore, the outlet valves
are filled with sodium to aid cooling, and the intake camshaft
offers infinite phase adjustment, setting the engine’s
valve timing to the driver’s requirements.
All this technology brings together power and economy in one
appealing package for consumers: 175bhp at 5,500rpm and 260Nm
of torque maintained from 1,600 to 5,000rpm is complemented
with an average fuel consumption of 6.9L/100km (40.9mpg). “It’s
full of technology, and is the best in its class for torque,
power and pleasure,” concludes France’s Christophe
Congrega. |
