The Volkswagen Jetta sedan comes in five different trim levels for 2009: S, SE, SEL, Wolfsburg, and TDI. The S, SE, and SEL are powered by a 170-horsepower, 2.5L 5-cylinder engine, matched either with a 5-speed manual gearbox or with a 6-speed automatic transmission with Tiptronic and sport mode. Top-of-the-range SEL models only offer the automatic. The Wolfsburg is a special edition that gets its power from a 2.0L turbocharged 4-cylinder engine making 200 horsepower and 207 ft-lb of torque. It features special badging, premium wheels, and leatherette seating, and can be equipped with either a 6-speed manual or the 6-speed automatic transmission. The TDI returns to the Jetta lineup after a brief hiatus. Jetta TDIs are available in both the sedan and the wagon. A 2.0L direct-injected turbodiesel produces 140 hp and 236 ft-lb of torque, and can be mated to either the 6-speed manual or the 6-speed automatic transmissions. The EPA rates the Jetta TDI at 30 mpg city / 41 mpg highway. The new SportWagen boasts a surprising amount of cargo space. With the back seat up, there's 32.8 cubic feet of space, but with it folded forward the cargo area expands to nearly 67 cubic feet. An optional fold-flat front passenger seat provides additional cargo space. The GLI is a performance-oriented sports-sedan model that is powered by the same 2.0L turbocharged 4-cylinder found in the Wolfsburg. The GLI also includes a distinctive honeycomb grille, lower-body trim, red brake calipers, large round taillights, dual stainless exhaust tips, special sport seats, an F1-style, flat-bottom steering wheel, and aluminum interior trim. On both the Jetta sedans and SportWagens, front thorax-protecting side airbags are standard, along with full-length side-curtain bags. Side thorax bags for rear occupants are optional. All Jettas and GLIs also include anti-lock brakes with engine braking assist, and an electronic differential lock for improved traction. Volkswagen's electronic stabilization program (ESP) is now standard across the line. All Jettas come with air conditioning, cruise control, a CD sound system, eight-way adjustable front seats, power windows and heated mirrors, and tilt/telescopic steering standard. The SE adds a leather steering wheel and shifter, power sunroof, ten-speaker stereo with 6-disc CD changer, a 60/40 split folding rear seat and alloy wheels. The SEL adds 17-inch wheels, body-colored valences, and a special instrument cluster. TDI models are outfitted as a mix between S, SE, and SEL trims. Popular options include a navigation system and various sport styling kits that give the Jetta a high-performance look. The same package is available on the GLI, along with a special rear wing spoiler and front lip spoiler.
