Major changes included: The first generation Caliber is a compact with SUV attitude. With crossover-like styling, the Caliber is as unique as it is versatile. Four trim levels are offered for the Caliber, including the SE, SXT, R/T and SRT4. A 148-hp 1.8-liter four-cylinder engine powers the SE and SXT models, while a 172-hp 2.4-liter four-cylinder powers the R/T model. The high performance SRT4 model gets a turbocharged 2.4-liter four-cylinder engine making 285 horsepower. A 5-speed manual transmission comes standard on the SE model, while all other models (except for the SRT4) come standard with a CVT (Constantly Variable Transmission). A 6-speed manual is the only transmission available for the SRT4. All-wheel drive was offered on the R/T model from 2007-2008.
