A few years after Lexus touched off the luxury-crossover craze with its RX 300, Cadillac chose to offer the SRX--a completely different, angular tall wagon with a rear liftback built on its rear-drive CTS sedan chassis. Although the SRX was excellent, its showing in a marketplace seeking stylish RX-like crossovers wasn't good. Since it introduced the SRX as a 2004 model, Cadillac has sold a total of 120,000; Lexus sells about 90,000 RXs every 12 months.

Porsche Macan gets four-cylinder powerplant

The new entry level Porsche Macan, shown alongside the new Boxster and Cayman GTS at the Beijing motor show, has become the first Porsche model since the 968 to use four-cylinder power. Parent company Volkswagen's EA888 engine -- as used by a wide range of models from Volkswagen, Audi, Skoda and Seat -- will motivate the new Porsche SUV. The turbocharged 2.0-liter inline four-cylinder direct-injection unit, boasting the same state of tune found on the Golf GTi Performance Package, develops 234 hp and 258 lb-ft of torque between 1,500 and 4,500 rpm.

Rod Millen held the world record at Pikes Peak for 13 years with a time of 10 minutes, 4.06 seconds.
