New Alfa Romeo MiTo & Giulietta Quadrifoglio Verde price & spec – costs from £20,210 & £28,120

The new Alfa Romeo Giulietta Quadrifoglio Verde (pictured) costs from £28,120 Alfa Romeo doesn’t have a huge amount to play with at the moment with its range in flux and plans to boost sales with new models. But although range-topping cars are not big sellers, they are good to shine a performance glow on the brand, which is why the Alfa Giulietta Quadrifoglio Verde and MiTo Quadrifoglio Verde (that’s the MiTo and Giulietta Cloverleaf to you an me) arrived at the Geneva Motor Show in March. Now both are about to go on sale in the UK, so we get prices and specs.

From 'Made in China' to 'Designed in China'

Visitors to the recent Auto China in Beijing may have noticed an impressive new Chinese sports car – called Aculeus – on one of the smaller exhibitor stands. The concept car is the latest project undertaken by CH-Auto Technology Corporation – one of a growing number of automotive R&D service companies based in China that provides support to the OEMs. The company was established in August 2003 by Lu Qun, an engineer who originally trained at Tsinghua University and later specialized in engine development testing.

Mountune will upgrade your Focus ST, Fiesta ST

UK-based Ford tuner Mountune set up shop in the U.S. just a couple months ago, and is already offering upgrades to the Ford Focus ST and the Ford Fiesta ST. Mountune is Ford's official partner in Europe, and their experience goes back 30 years Mountune comes from a slightly different branch of Ford tuning that North American buyers are used to -- their specialty has been tuning Ford's smaller cars in Europe rather than muscle cars, and they've worked on everything from Escorts to Focuses (though perhaps not the Escorts and Focuses that we're used to).
