Chevrolet Sonic at the 2011 Detroit auto show

One of GM's numerous debuts at the 2011 Detroit auto show was this: the Chevrolet Sonic. Shown as a hatchback and four-door notchback, it's one of The General's weapons to tackle the now-globalised Ford Fiesta and its ilk. Good spot. That's because this is the US-spec Aveo - albeit shown in US-only notchback form as well as the more Euro-flavoured hatchback.

BMW Concept 4-series Coupe (2012) first photos

BMW is overhauling the 3-series Coupe - it'll be replaced in 2013 by the new 4-series Coupe and Convertible, previewed in this remarkably production-ready concept car. Munich reserves the 'Concept' moniker for its show cars which are in reality showroom ready. So strip away the sexed-up exhausts, 20in wheels and other trinkets and what you're looking at here is the new 2013 BMW 4-series.
