Cadillac CTS Sport Wagon
* All the car launches from Detroit * New Mercedes E-Class and Jaguar XFR * Toyota Prius, too...
Is the BMW 5 Series estate under threat? This is the Cadillac CTS Sports Wagon, which goes on sale in the UK this autumn, and which has its executive car rivals in its sights.
Cadillac says the car has been designed with aerodynamics in mind, to ensure the car retains a sporty drive despite its extra carrying capacity.
Luggage space is 720 litres with the seats up and 1452 litres with them down.
Although no engine details have been confirmed, the UK engine range is expected to include the 208bhp 2.8-litre V6 and 307bhp 3.6-litre V6 from the saloon. A 247bhp 2.9-litre V6 diesel is also being developed for use in Europe.
Gearbox options are expected to include a six-speed automatic and manual, while four-wheel-drive will also be an option.
Other features include 19-inch alloys, a 40GB internal hard drive, sat-nav and full leather interior. A panoramic sunroof will be available as an option.
No prices have been released, but the Sports Wagon is expected to start from around 28,500.
