The Solstice GXP's Ecotec turbo spits out 260 high-spirited horses and . . . . . from just two liters of displacement . . . . That's a remarkable 130 bhp per liter: the highest specific-output engine GM has ever produced.

The pistons are subject to a lot of heat flux due to the high power density, so we went to what's called a 'salt-core' piston with oil galleys and oil-jet cooling . . . . . . . . . . . . . . The unique dual-scrolled turbocharger, which keeps exhaust pulses from cylinder #1 and #4 separate from those of cylinders #2 and #3 until they enter the turbine housing, delivers up to 20 psi of boost with nearly instant response. There's virtually no lag with this system.

The turbocharger itself is oil cooled for long life, and its compact design allows tight packaging. The 2.o turbo engine produces 83 more horses than the 2.4, yet delivers nearly the same fuel economy.

"The 260 bhp Ecotec turbo didn't exist when we started," notes Performance Manager Dean Perelli. "And this is its first application, so the challenge came in developing a brand-new engine and integrating it in-to the Solstice. It's a joint venture among General Motors subsidiaries in Germany, Sweden and Italy."

Chain-driven camshafts means there's no belt to replace. Sodium-filled exhaust valves deal with high temperatures and 9.2:1 compression ratio adds to engine's efficiency.

And if one happens to be an idiot, they can also do a fair bit of damage. Watch this twit drop one into water.

The GXP uses the same-sized wheels as the standard car, but the tires have a higher speed rating and a directional tread design with a three-season rubber compound. the GXP tires thus gave a better dry-road handling.

The GXP logo appears in the speedometer and on the deck lid. Easiest way to identify a GXP, though is by its D-shaped brake-cooling intakes.

Definitely bigger heads. Or the fact that the height-adjustable seat does not go quite as low as the non-adjustable seat.

Good observation. On the long spec list, of which I clearly picked only a few, I intentionally picked some because they had unexpected differences between Base and GXP. Fuel tank has some surprises too. Different tank ? Different pump ? Incorrect data ? Typo ?

The fuel system is different to make it lower profile to fit under the coupe "trunk" liner, but I do not know which specific parts are different, and how much is just different arrangement.

Not needing the mahan-temple to support the glass rear window when the top is down possible also allowed that height to be lower.

On 4 January 2004, two years after Pontiac introduced the Solstice concept at the Detroit auto show, GM displayed a nearly identical-looking but totally different Solstice and announced to the world that this car would enter production in 2005 as a 2006-model. Assembly would take place at GM's venerable plant in Wilmington, Delaware, an announcement that brought shouts of joy from both Wilmington and Detroit.

We even added a third shift in January 2006. Our line rate is seven cars an hour, so to hit our target of 156 cars a day, we needed three shifts. Fortunately we've been able to pull in people from the Linden (New Jersey) and Baltimore assembly site . . .

Originally we thought the Solstice was going to be built at Mexico. At the same time, [assistant chief engineer] Bruce Kosbab was still developing the car, so we were working in parallel. Every time he'd have some change, we had to reflect that back into the build process. Then in April 2003, we got notice that we were switching plants to Wilmington DE.
