2005 was a transitional year for the Volkswagen Jetta. In anticipation of a redesigned vehicle introduced mid-year, the previous year's models were sold well into the current year, and no changes were made to the Jetta wagons.

When the restyled New Jetta sedans did arrive, they were longer and heavier than previous models, with a length of nearly 15 feet and a weight of just under 3,300 pounds. Upgrades included a longer front end, new taillights, an improved safety system with additional airbags, a new steering system, and a new, more rigid suspension.

The standard engine was also upgraded, to a 150-horsepower, 2.5-liter five-cylinder powerplant, which was linked to a standard five-speed manual transmission. A six-speed automatic, also new for 2005, was optional. The 1.9-liter turbodiesel engine, which pumped out 100 horsepower, was also available.

In addition, standard features for the Jetta sedan were expanded for 2005, and included air conditioning, power windows, power door locks, a CD player, anti-lock brakes, and traction control. Stability control was standard on the higher-end trim packages, as were rain-sensing windshield wipers, heated seats, dual-zone automatic climate control, a CD changer, and a trip computer.

Drivers' reviews of the 2005 Jetta were mixed. Some drivers were impressed with the longer, heavier, more powerful vehicles while others felt the changes did little to improve the car. Some expressed concerns about the car's fuel economy, performance, and styling, though most felt the Jetta's interior appointments, safety features, and comfort were noteworthy.
