Honda CR-Z Mugen (2010) first official pictures

Since its conception, Honda has been trying to persuade us that its CR-Z isn't merely a woolly hybrid but is in fact a proper sports car. As if to prove the point, Honda has announced that Mugen-fettled versions of the hatch are to be released for the British market. Recently making a splash in the UK with their banzai track-focused version of the Civic Type R, Mugen started in 1973 and specialise in building and tuning Hondas.

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.

Novitec Alfa Romeo 8C Spider adds boost for a sensuous 600 hp

Novitec has laid hands on the near-perfect Alfa Romeo 8C to create the 8C Spider Kompressor, a car the tuner claims is the “most powerful street-legal Alfa Romeo of all time.” Heady words, but they're nicely backed up by a supercharged version of the 4.7-liter Alfa V8 cranking out 600 hp and 434 lb-ft of torque. That's up from approximately 450 hp and 346 lb-ft on a stock Alfa Romeo 8C Competizione. Tweaks supporting the force-fed mill include a water-to-air intercooler, custom injectors and revised fuel and ignition mapping, plus a variable stainless-steel exhaust system.
