Ford to introduce inflatable seatbelts

When the 2011 Ford Explorer hits showrooms, its move to a unibody platform won't be the only major change. Ford will use the next-generation Explorer to introduce inflatable seatbelts for rear passengers. According to Ford, the inflatable seatbelt will help distribute crash forces across five times more body area, compared with traditional seatbelts.

Driven: BMW i8

When BMW unveiled the Vision EfficientDynamics concept at the 2009 Frankfurt motor show, we wrote: "for our money, it's the first time a major carmaker has really attempted to communicate ‘green' technology in an aesthetic sense." Fast-forward five years and we've swapped the show halls of the IAA for a beauty spot on the north-west coast of Scotland. And, while the car's name has changed to i8, our sentiment towards this genre- and era-defining car remains. Admittedly the production car's design execution hasn't received the universal praise of its concept forebears, but, on a remote outpost of the British Isles, a Protonic Blue i8 couldn't look more exotic.

Alfa Romeo 4C arrives stateside in New York

Not long after the last transport departed New York Harbor with a cargo of unsold 164s, an Alfa Romeo executive was probably quoted as saying, "we will return next year!" We have been eagerly anticipating the return of Alfa Romeo for the last 19 years, long enough for the last Milano to rust whence it came, every year the brand just another year away! Well, this year -- yes, this year, finally, no really -- the Alfa Romeo 4C heralds the brand's reintroduction to America -- just as it did last year, remember -- as early as this summer. You'll have to forgive us for such skepticism -- we've been burned by our desire to invoke Italian driving passion and all that, but it's also hurting the Fiat dealers who scrape by on a lack of product.
