"Targa" means it has a folding roof section (cloth-covered magnesium frame) that stows automatically behind the rear glass in a complicated and dramatic fashion.
The "4" says it's all-wheel-drive.
And the "GTS" means it comes packed with a host of performance-enhancing add-ons. These include bumping the 3.8-liter six-cylinder engine from 400 horsepower to 430 horsepower and adding unique 20-inch wheels, an active suspension, the Sport Chrono package (lowers 0-60 mph time to 4.1 seconds and adds a Sport Plus setting) and a sport-tuned exhaust.
Porsche says 13% of current 911 buyers are choosing the Targa model -- half coupe, half convertible -- and the number is growing each month. So it saw a chance to expand the menu.
This model will start at $133,795 and is scheduled to hit the U.S. market in late April.
On the SUV front, Porsche announced in Detroit that it had given its Cayenne Turbo S SUV a midlife update that adds more of everything.
Horsepower on the 4.8-liter, twin-turbocharged V-8 jumps from 550 to 570. Torque is now 590 pound-feet, a jump from 553 pound-feet.
A 0-60 mph run now takes a scant 3.8 seconds, nearly half a second faster than the earlier model.
Carbon ceramic brakes are standard, as is a suspension that actively mitigates body roll, 21-inch wheels, LED headlights, and a full leather interior with carbon fiber accents. Starting price is a cool $158,295 when it goes on sale in April.
