Luxury brands kick off Los Angeles Auto Show unveilings

(General Motors)

General Motors' Cadillac brand and Porsche have both released pictures of worldwide debuts due to be unveiled at next week's LA Auto Show.

GM has unveiled the new Cadillac CTS Coupe, due for delivery in the spring of 2010, as it returns to the LA show with an expanded presence from last year. The two-door model will feature a 3.6L V-6 engine delivering 306 horsepower and is two inches (51mm) lower and shorter than its CTS Sport Sedan cousin. The CTS Coupe will be available in rear-wheel drive and all-wheel drive versions, and Cadillac claims that it will deliver fuel efficiency of 27 mpg (8.7L/100 km) on the highway. Cadillac has not yet confirmed whether the model will be available outside of the US, although previous CTS models have been made available worldwide.

Porsche has also released images of the 2011 Spyder, which weighs in at 2811 pounds and will be the lightest Porsche available on the market. Combined with a 3.4L engine delivering 320 horsepower, the lightweight Porsche will be able to go from 0-60 in 4.6 seconds. It will be available in international markets from February 2010.

The pictures of the CTS Coupe and 2011 Boxster Spyder are early previews in a series of world debuts expected at the Los Angeles Auto Show. Other brands expected to unveil models include Dodge, Honda, Toyota and Volkswagen.
