2013 VW Golf TDI BlueMotion Mk 7 costs from £20,335

Starting at £20,335 for the 3-door BlueMotion and rising to £20,990 for the 5-door, the new Golf also emits just 85g/km CO2 (which would have been enough for free London Congestion charging, but not any more) which is 15 per cent better than the previous Mk 6 TDI BlueMotion managed. VW has managed to tweak the Golf BlueMotion’s economy figures still further by reducing weight, fitting super low rolling resistance tyres (that run with higher pressure), longer gear ratios, stop-start and aerodynamic tweaks. Thos aerodynamic tweaks includes modifications to the front of the Golf to reduce drag by nearly 10 per cent, adding a roof spoiler, air guide elements on the back window, a masked front grill, smoother underfloor and a reduction of ride height by 15mm.

2013 Lamborghini Gallardo Spyder revealed

The 2013 Lamborghini Gallardo Spyder has been revealed, joining the 2013 Gallardo Coupe as the last facelift for the Gallardo range. Now we get the 2013 Lamborghini Gallardo Spyder – the open air Gallardo – with much the same minor tweaks to keep the Gallardo range fresh until we get its replacement. That means a bit of fiddling at the front and back for some sharper lines and a bigger outlet at the back to improve cooling for the Gallardo’s V10, which offers 560bhp and 0-62mph in 4 seconds, and the Gallardo LP560-4 Spyder gets a new set of polished alloys.

Chevrolet Spark EV tops EPA's fuel-economy rankings for 2014

The 2014 Chevrolet Spark EV has been named the most fuel-efficient vehicle by the EPA and the Department of Energy in a new ranking for 2014. The Spark EV returns a combined 119 mpg equivalent, achieving 128 mpg in the city and 109 mpg on the highway. Chevrolet's pure-electric hatch displaced last year's chart topper, the Scion 2013 iQ EV, with its 121 mpg equivalent rating, but the Scion is not offered for the 2014 model year, so it didn't make the list for the U.S.
