BMW 320d EfficientDynamics Review & Road Test (2010)

BMW 320d EfficientDynamics Review It comes as something of a shock to realise that the BMW 3 Series has been around for thirty five years, not least since I remember its launch and the stir it caused by offering as it did not just a stylish compact saloon car, but one which offered both prestige and performance. It was also streets ahead of what, until the 3-Series came along, we thought of as a cracking little BMW – the BMW 2002. Thirty five years is a huge amount of time in the world of cars and the 3-Series has changed out of all recognition in the intervening time.

Opel Trixx concept for the Geneva Motor Show

Opel/Vauxhall has released first details of the Trixx small car concept to be shown at the Geneva Motor Show next month. Martin Smith, Opel/Vauxhall executive director of design, says: "Trixx shows our vision of an innovative, ultra-compact car in the three-metre-class, with an expressive, exciting design, and meets a variety of mobility requirements with its clever, highly versatile interior concept." Trixx has an inflatable rear seat, sliding electric doors, and a push-button roof hatch that allows it to carry extra-long objects upright. The versatile car can carry up to three adults and a child, and as a one-seater it turns into a substantial load carrier.

SAIC Leaf concept

The Shanghai Automotive Industry Corporation (SAIC) will unveil this futuristic concept at next week's Beijing motor show. Called the Leaf, the new concept has no relation to Nissan's concept car shown in Tokyo last year. It is a much more fanciful two-seat concept car whose design is entirely open to the elements, and it also features a slew of environmentally-friendly technologies.
