Jaguar lines up 4-, 6-cylinder engines

Jaguar hasn't offered a four-cylinder engine since 1948 and no V6 since the small, lackluster X-Type was pulled from the United States four years ago.

Porsche 911 Carrera GTS arrives

Porsche 911 Carrera GTS The news that the Porsche 911 Carrera GTS will be making an appearance at the Paris Motor Show before arriving in showrooms by December should be followed soon by an announcement that there is to be a Limited Edition run of a 911 Speedster.

Though not a showman by trade, Lutz is bankable for amusing, bald-faced assessments of his employer, his critics and the auto industry at large.
