McLaren MP4-27 unveiled

Vodafone McLaren Mercedes has revealed the MP4-27, its contender for the 2012 FIA Formula 1 World Championship.

Although very much an evolution of last year’s car, McLaren is saying that actually very little has been carried over from the MP4-26 unchanged.

Visually, the most obvious differences are the revised side pods and narrower rear bodywork. However, one feature that hasn’t appeared is a stepped nose section like that of the Caterham CT01, the only other 2012 Formula 1 car so far unveiled.

Speaking about the forthcoming season, Team Principal Martin Whitmarsh said: “The 2012 season will be an important one for Vodafone McLaren Mercedes: having finished second in the constructors’ championship for the past two seasons, we’re determined to mount a sustained, hard challenge for both world titles.

“For 2012, we are well aware that Red Bull remains a very powerful and capable operation, and that both Ferrari and Mercedes AMG are ramping up their operational capacity. We have no room to be complacent - what you see today only scratches the surface of what we’re planning to deliver to the track both from an engineering and operational point of view throughout 2012.”

McLaren has released some technical details for the MP4-27, but unfortunately - for obvious reasons - these don’t include any power or performance stats.

Alfa MiTo TwinAir arrives

Image
The Alfa Romeo MiTo supermini is now available with the innovative two-cylinder TwinAir petrol engine. Although its capacity is only 875 cc, a turbocharger and the MultiAir electro-hydraulic valve control system mean it produces a respectable 83 bhp (62 kW / 85 PS) and 145 Nm (103 lb/ft) of torque. Performance might not be scintillating - the 0-62 mph (100 km/h) sprint takes 12.5 seconds and maximum speed is 108 mph (173 km/h) - but the TwinAir’s trump card is efficiency. Carbon dioxide emissions are only 98 g/km, a level that brings numerous benefits for UK drivers including zero road tax, a full discount on the London Congestion Charge and qualification for the lowest company car benefit-in-kind rate. Fuel economy is also decent and, according to the official figures, a TwinAir-powered MiTo will manage 67.3 mpg (4.2 l/100km) on the combined cycle. Impressive maybe, but still some way off the 78.5 mpg (3.6 l/100km) of the existing 1.3 JTDM-2 diesel MiTo. However, any
