and the High Output engine were discontinued for the 2008 model year and sales dropped as information spread that Chrysler was going to discontinue the PT Cruiser in the near future. For 2010, the last year of production, one trim level was offered, the PT Cruiser Classic. It included a 2.4 L I4 engine producing , standard four-speed automatic transmission with overdrive, AM/FM stereo with single-disc CD player, auxiliary audio input jack and six speakers, rear-mounted spoiler, air conditioning, cruise control, tire pressure monitoring system (TPMS), front and rear side SRS airbags, keyless entry with two remotes and panic alarm, ABS anti-lock brakes, and sixteen-inch alloy wheels. Optional features included leather seating surfaces, a power front driver's bucket seat, an engine block heater, a power tilt-and-sliding sunroof, and heated dual front bucket seats. Exterior color options were Bright Silver Metallic, Brilliant Black Crystal Pearl Coat, Deep Water Blue Pearl Coat, Inferno Red Crystal Tinted Pearl Coat, Silver Steel Metallic, and Stone White Clear Coat. The only interior color option was Pastel Slate Gray. Safety In 2002, Euro NCAP gave the PT Cruiser a three (out of five) stars rating. The car received bad results in the frontal impact test (6 out of 16 possible points). The height of the seats and side airbags helped to attain a maximum score of 16 points in the side impact test. The low frontal scores are in part explained by the cushioning near the knees, designed to protect unbelted occupants, which is not a factor in the EU where passengers must wear seat belts. For 2008, the Insurance Institute for Highway Safety gave the PT Cruiser the highest rating of Good overall for occupant protection in frontal crashes and the lowest overall rating of Poor for side crashes. It was the only small car to not offer electronic stability control.
