The Audi A8 made its public debut at Detroit. Built from aluminium, the Audi's new flagship bears a striking resemblance to the current A4, but is expected to be the largest car in its class. All A8s will get Audi's quattro four-wheel drive and eight-speed auto as standard, plus a sophisticated safety system called pre-sense.
Audi brought a specially-revised version of the e-tron to Detroit. The car is thought to preview what a future Audi R4 might look like. The concept is smaller than a TT, and despite retaining the original e-tron's electric drivetrain, it weighs 250kg less than the larger car.
As far as the mainstream is concerned, this was the most important car at the show. Expected to sell in 122 countries, the third-generation Focus will form the basis of up to ten distinct models. Ford's confidence couldn't be any higher; there is potential for the new global Focus to become one of the world's best-selling cars.
The fourth member of the E-class family made its debut at Detroit. The Cabriolet gets a fabric roof rather than a folding hardtop, but Mercedes insist it's one of the quietest cars in its class. The car also gets a new deflector called the AirCap that directs turbulent air away from the cabin.
This is the new plug-in electric version of the 1-series coupe. The concept picks up where the Mini E left off, except the electric motor is mounted on the rear axle to drive the back wheels. Expect to see a production version offered to pre-approved customers for leasing some time soon.
BMW may not have given its range-topping Z4 a standout name, but the 335bhp 3.0-litre straight six should at least mean the car's performance is memorable. The M Sports Package and M suspension come as standard, as does a special exhaust designed to deliver the perfect acoustic background.
Cadillac's striking coupe was one of Detroit's main attractions. The car's stats are certainly worthy of admiration; GM's 6.2-litre supercharged V8 delivers 556bhp, propelling the coupe to 60mph in 3.9secs. There's even rumours it might be coming to the UK. Don't hold your breath though.
Cadillac's flaghip saloon was shown at Detroit as a plug-in hybrid. A 345bhp 3.6-litre V6 engine provides the grunt when electric reserves are exhausted. The production car will replace both the STS and DTS models.
The Aveo concept offered a glimpse of Chevrolet's new supermini, and hinted at the brand's first hot hatch. The RS was shown with a 1.4-litre turbocharged engine, producing 136bhp. The production version of the Aveo should reach the UK by 2011.
As Fiat begins to drip feed its technology to Chrysler, the 500 BEV cropped up at Detroit to show that the transfer was not a one-way street. The 500 uses an electric drive system that Chrysler has been developing for the past three years. Unfortunately, the car was revealed as a packaging exercise rather than design reality.
The latest Ford Mustang was a predictable hit at Detroit, not least because it featured a new 5.0-litre V8 engine developing 412bhp. Despite offering significantly better performance than the outgoing 4.6-litre V8, the new engine's cutting-edge design means it returns 5 per cent better fuel economy.
Honda revealed the US-spec production version of the CR-Z at Detroit. The bold design of the concept may have been smudged a little in the transfer to the production line, but Honda are still promoting the car as the first hybrid sports car. It gets a 102bhp 1.5-litre engine complimented by a 20bhp electric motor.
The Blue-Will's appearance at Detroit was the first time it had been seen in the US. The concept is intended to showcase Hyundai's hybrid techology. The car features significant use of bio-plastics, as well as a sunroof which incorporates a solar panel.
The rebadged Lancia Delta is a taste of things to come at Chrysler. Fiat intends to prop up the US giant's flagging sales by reheating Lancia's product line. What could possibly go wrong?
Don't be fooled by the Mini Beachcomber's Moke-inspired body; the car is four doors and a sensible interior a way from the new Countryman. The production car will be the largest Mini yet made, and higher spec models will get four-wheel drive.
The FT-CH concept unveiled at Detroit is Toyota's smallest hybrid yet, and hints at what a future competitor to Honda's CR-Z might look like. The FT-CH has been designed to appeal to a younger audience than the best-selling Prius currently caters for.
VW's New Compact Coupe concept was one of the few Europeans to cause a stir at Detroit. The NCC is thought to be close to a production reality and is likely to be badged as the coupe version of the next Jetta. Primarily designed for the US market, the NCC was shown with a petrol-electric hybrid system that VW claims is good for 0-60mph in 8.1secs and yet is capable of 67mpg.
