As Volkswagen’s top seller, the Jetta is important to both VW and the entire Volkswagen group. Through the first three months of this year VW sold 37,368 Jettas, down slightly year over year. Just in time to energize those sales and VW has put some updates into the 2015 the Jetta, which previewed at the New York International Auto Show. The changes are geared to improved fuel economy and emissions.
Better fuel economy/cleaner emissions profile
A new Clean Diesel TDI engine (dubbed EA288) has been added to much of Volkswagen’s fleet including the 2015 Jetta. The 2.0 liter, 150 horsepower engine, offers an eight percent improvement in efficiency. Paired with a manual transmission, a manufacturer’s estimated fuel economy of 32 mpg city/45 mpg highway/37 mpg combined is predicted. Maximum torque of 236 lb.-ft. is available from 1750 rpm-3000 rpm.
VW’s modular diesel system (MDB) reduces emissions with exhaust system components and the injection system, turbocharging systems, and forced induction cooling within the intake manifold module. The new TDI engine reduces internal friction, by using piston rings with lower pretension and very low-friction camshaft bearings.
A catalytic converter reduces nitrogen oxides (NOx) using the additive AdBlue additive and improves fuel economy. This enables the Jetta to conform to the current and future U.S. emissions standards.
Design updates enable aerodynamics and Jetta goes all LED
The front end updates give the Jetta a touch of bling as well as a wider, more substantial stance. The styling includes a new front bumper, day time running lights with an L-shaped LED that runs around the xenon modules as well as chrome in between the LED string and the daytime running lights and available Bi-Xenon headlamps. Adaptive headlamps, which track steering at 15 degrees illuminating corners into a turn, are also available.
The Jetta’s trunk lid gets an integrated spoiler. The line created by the spoiler’s edge sweeps into the rear fenders joining the car’s side character lines. New LED taillights are available on GLI and Hybrid only and feature a bright stripe. A redesigned VW logo and a new bumper complete the updated look of the Jetta’s rear.
Reducing air drag
The new front bumper reduces air drag by optimizing air intakes. Details such as aerodynamic improvements to the rain gutters on the sides near the A-pillars also optimize air flow. A closer look reveals underbody panels at the rear axle and sill covers with wheel spoilers. Jetta models equipped with the 1.8T engine also have modified brake ventilation channels. Jetta GLI and Jetta Hybrid models sport special aerodynamic elements such as new front/rear spoilers and sill extensions.
To shorten the time needed to warm up the engine, VW has added a shutter that closes the radiator grille. The radiator remains shut while driving if the engine coolant temperature drops below a predefine temperature threshold. It then opens and closes on demand based on temperature and speed. The closed radiator pushes air around the car body, which improves aerodynamics.
There are a few updates to the Jetta’s interior. On mid- and high-level trims the dash gauges can now framed in chrome-edged tubes, with an available color multifunction display nestled in between. Optional new features based on trim include a new multifunction steering wheel, redesigned air vent controls, piano black accents on the center console and around the gear shift lever, new chrome accents around the dual-zone climate control, ambient lighting, and new fabric colors and designs for the seats.
New driver assistance safety features
Blind spot detection plus rear cross-traffic alert and frontal collision warning, as well as Bi-Xenon headlights with Adaptive Front-lighting System (AFS), turn signal, and LED Daytime Running Lights are now available as options.
