Pontiac Solstice's four-wheel disc brakes consist of 11.7-inch (297 mm) ventilated front rotors and 10.9-inch (277 mm) rear rotors, which combine to provide assured braking capability. ABS (with dynamic rear proportioning) is available.



Pontiac Solstice 2007 - Two compact powerhouses

The Ecotec 2.0-liter Turbo engine that powers the GXP is GM's first direct injection offering in North America . Gasoline direction injection technology helps the engine produce more power without sacrificing the fuel economy of a small displacement port-injected engine. The Turbo 2.0-liter produces 260 horsepower* (194 kW) at 5300 rpm and 260 lb.-ft. (353 Nm) at 5300 rpm*.

The base model Pontiac Solstice 2007 is powered by a 2.4L Ecotec four-cylinder engine that produces 177 horsepower (132 kW) at 6600 rpm and 166 lb.-ft. of torque (225 Nm) at 4800 rpm.*

Power output aside, the 2.0L Turbo version shares a number of traits with its naturally-aspirated sibling in the Ecotec family. The features include:

- Dual overhead camshafts (DOHC) and four valves per cylinder
- Twin counter-rotating balance shafts
- Low-friction, roller-finger follower valvetrain with hydraulic lash adjusters
- Low-maintenance chain-drive for the camshafts
- Extremely compact dimensions and low mass
- Direct mounting of all accessories to the engine structure to eliminate common sources of noise, vibration and harshness
- Full circle transmission attachment is more rigid than most 4-cylinder powertrains for reduced noise and vibration
- GM Oil Life System for optimum oil change frequency (included with optional driver information system)
- No routine maintenance apart from oil/oil filter changes
- Innovative cast-in oil filter housing eliminates crawling under the car to perform oil changes. The design also eliminates throwaway oil-filter "cans" that retain used oil that typically end up in landfills


A 3.91:1 axle ratio is standard on the base level Solstice with the five-speed manual powertrain. The GXP model with the manual transmission comes with a 3.73:1 axle ratio.

*Horsepower and torque are SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.

**Preliminary, pending SAE certification.
