Evolution of the 3: BMW begins sales of sixth-generation sedan

BMW staged the U.S. launch of the sixth generation of the stalwart 3-series at the Detroit auto show this week, which makes this as good a time as any to take a look back at the car that other sports sedans aspire to be. The small sedan hit the scene in 1975, just three years after the 5-series, as a successor to the BMW 1600, the 1600ti and the 2002.

Monterey in a Mulsanne – a Bentley mission to Pebble Beach

After a ten-and-a-half-hour flight from London, the idea of steering headlong – and solo – into the early Los Angeles rush-hour traffic in a five-and-a-half-metre-long, left-hand drive Bentley Mulsanne (worth some £230,000 with extras) and on the other side of the road to which I am familiar, might seem a little daunting. But as soon as I sink into the super saloon’s big leather seats, Bluetooth my iPhone to stream some music via the Naim premium audio, turn up the air-conditioning and press the accelerator gently, all becomes well. LAX Airport may be my starting point but the final destination is the Monterey Peninsula towards San Francisco, some 400 miles northward, for the world-famous annual classic car show Pebble Beach.

New Porsche 911 Speedster reportedly in the works

When European-car importer Max Hoffman suggested to Porsche that the American audience might like a cheaper, open-top version of the company's 356, Stuttgart responded with the Speedster. And while every Porsche partisan is a special snowflake -- some love road-going racers like the 904, others can't imagine life without a roof-rack-equipped 912, others go gaga for anything with a legit, lift-off Targa top, and some folks just really, really, really love 924s -- the Speedster's the light, lovable kid brother for which any fan of the marque has a measure of affection. Porsche knows it, and as such, they've introduced limited Speedster models of every 911 series since the 3.2 Carrera -- except for the oft-maligned 996 (which is still loved by its proponents, IMS-bearing issues aside).
