The Volkswagen Jetta sedan comes in three different models for 2008: S, SE, and SEL. The entire line is powered by a 170-horsepower, 2.5L five-cylinder engine, matched either with a five-speed manual gearbox or with a six-speed automatic transmission with Tiptronic and sport mode. Top-of-the-range SEL models only offer the automatic. Then there's also the GLI, a performance-oriented sports-sedan model that's powered by a 2.0L turbocharged four-cylinder engine making 200 horsepower and 207 lb-ft of torque. 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. The Jetta sedan can accelerate from zero to 60 mph in 8.2 seconds with the manual transmission, but the GLI can dash to 60 in only 6.9 seconds. Both engines attain 29 mpg in the EPA highway estimate. On both models, front thorax-protecting side air bags 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. SE, SEL, and GTI models get standard electronic stability control. All Jettas come with air conditioning, cruise control, a CD sound system, eight-way adjustable front seats, and tilt/telescopic steering standard. Top SEL models add big 17-inch alloy wheels, heated front seats, a sunroof, and a ten-speaker sound system with six-disc changer. Top options include a navigation system and a sport styling kit that gives 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.
