Concept Car of the Week: Mercedes-Benz C111, C111-II and C111-IID

In 1962, Mercedes-Benz launched a research program to investigate the development of the Wankel rotary engine and its potential both on the road and track. While the early mule wasn't a looker, the prototype's design continued to evolve until a public unveiling of the C111-I concept, designed by Bruno Sacco, at the 1969 Frankfurt motor show. The coupé may have looked like the systematic further development of the Sport Light models from the ‘50s with its gullwing doors, but it wasn't a design study for a new SL.

Almost four years to the day after we first saw the VW Up concept car, Volkswagen is unveiling the real thing: this is the new VW Up city car, on sale in UK dealers in spring 2012.

Vauxhall Adam gets new 1.0 litre 3-cylinder engine, Cascada new new 1.6 SIDI turbo with 197bhp

Vauxhall Adam & Vauxhall Cascada get new engines Vauxhall (and Opel, for that matter) are on a mission to fit new, more powerful and more efficient engines in cars across their range, and new engines are on their way for the Vauxhall Adam and the new Cascada. The Vauxhall Adam gets a new 1.0 litre 3-cylinder engine from GM’s SGE (Small Gasoline Engine) family that will ultimately offer 3 and 4-cylinder engines up to 1.6 litres. The 1.0 litre 3-pot for the Adam gets 113bhp and 122lb/ft of torque (it’s Vauxhall’s take on the hugely successful 1.0 litre EcoBoost Ford are busy introducing across their range) mated to a new six-speed gearbox.
