Porsche is going to unveil its newly freshened Boxster and Cayman models at the LA Auto Show today. As you can see in the galleries below, their noses and tails have been redone with a touch of Carrera GT, but each car now has a unique look. More importantly, the engines and transmissions have been updated as well, with the 2.9L and 3.4L powerplants getting Porsche's direct fuel injection for a 10-25 hp bump depending on the model. Along with the extra oomph, owners will get better mileage with fuel economy rising 11-16 percent. Part of that boosted mileage comes from the direct-injected engines, but the newly available Porsche-Doppelkupplungsgetriebe, or PDK, double-clutch gearbox also deserves praise.

The base Boxster and Cayman will now have 255 hp and 265 hp respectively, and the S versions will be rated at 310 for the Boxster S and 320 for the Cayman S. A Cayman S with PDK and Launch Control will also get to to 62 mph in just 4.9 seconds. At the other end of the lineup, the Boxster with a six-speed manual will do it in 5.9 seconds. Gas mileage should run 25.5-26.4 mpg. The new models will hit the market in February 2009, with European prices ranging from Euro 38,600 for a base Boxster to 61,493 for a Cayman S. The full press release is after the jump, and we have official high-res images set up in the galleries below. Plus we'll have our own live, firsthand impressions in a few hours.
