Fiat unveils new 900cc TwinAir two-cylinder engine

Fiats of old used to feature noisy two-cylinders with a fetish for overheating, yet the Italians are at it again, this week releasing details of their new TwinAir two-cylinder 900cc engines. You can see how it works in our video below. The new engines, the first in a series of two-cylinders by the Italians, are designed to trump all other downsizing efforts. Headline figures from the 83bhp twin are 23% more power than the regular 1.2 four-pot and the same as a 1.4 16v - yet with 30% less consumption.

Chrysler details changes to minivan, Jeep Patriot

Wider use of the Pentastar V6, fascia changes and more luxurious materials in the interior are the key changes being made to the Chrysler Town & Country minivan and the Jeep Patriot for the 2011 model year. The changes come as Chrysler works to revive interest in its products after nearly two years of virtually no new-product activity while the automaker worked through a government-sponsored bankruptcy. Earlier this year, Chrysler unveiled the redesigned 2011 Jeep Grand Cherokee, which is now on sale.

Thomas Ingenlath: Volvo Concept C to end 'vanilla' design era [w/Video]

Volvo has promised a radical change in its future design language that will be embodied in its Concept C coupé, the first concept to be developed since head of design Thomas Ingenlath's appointment in July 2012. Our first look at the concept, which debuts at this month's Frankfurt motor show, comes from a video starring Ingenlath (see left). At first it seems to just show him sketching while he explains how some people see Volvo design as "vanilla" – nice, but not iconic or cutting-edge – but if we slow it down at around the 11-second mark, we get a preview of what we can expect.
