Concept Car of the Week: Heuliez H4 (1972)

With the H4, Heuliez set out into unexplored territories by offering a concept tailored to the needs of taxi drivers. If today's minivans are an integral part of our daily lives, this Peugeot 204-based H4 should be placed back in its original context in the early ‘70s, when this monovolume architecture still belonged to science fiction. Its dimensions are comparable to a Renault Modus although it's shortened by 140mm.

2015 Subaru WRX debuts at Los Angeles Auto Show

If you loved the rakish WRX concept that bowed in New York earlier this year, the production 2015 WRX, which debuted today at the Los Angeles Auto Show, may be a slight downer: decidedly less boy-racer than its predecessors, its sculpted fender flares and unique sheetmetal only slightly disguise its Impreza rootstock. But the WRX has always been more about performance than style, anyway, and Subaru says the new car will top its predecessor on that front. The '14 WRX's 2.0-liter turbocharged boxer-four squeezes out 268 hp and 258 lb-ft -- just a little bit more than the outgoing 2.5-liter turbo-equipped car.

Big car day in horse country at the Keeneland Concours d'Elegance

With a concours sprawling over the lush grounds of the Keeneland Race Course, there was almost too much to see. Attendance, at 6,000, was up again this year; there was a record number of entries, and attendees could park their rides in car corrals that surrounded the show grounds. "To drive up in your Cobra, Mustang or Mini and then nose up 10 feet from a Duesenberg or a Bugatti is pretty cool," said Tom Jones, event chairman.
