The turbocharged GXP version of the Pontiac Solstice has finally been unveiled in all of its Banana Yellow glory, according to our man on the floor, Stuart.

A few more details have emerged about the GXP’s 260-hp, 2.0L turbocharged Ecotec engine. For starters, it features a dual-scroll turbo with a lightweight turbine to reduce lag (it can accommodate up to 20psi of boost), an air-to-air intercooling system to chill the engine’s inhale and variable valve timing on both the intake and exhaust. Direct-injection technology is also included, a first for GM in North America.  

The engine was developed by GM Powertrain in both the U.S. and Europe and it stands as the company’s highest specific output engine ever at 2.1 hp per cubic inch of displacement.

Here are some more highlights of the 2.0T Ecotec:
  • Steel crankshaft
  • Forged connecting rods
  • Forged oil-galley pistons
  • Jet-spray piston cooling
  • 9.2:1 compression ratio
  • Aluminum cylinder head with sodium-filled exhaust valves
  • High-pressure engine-driven fuel pump
  • Variable pressure fuel rail
