You'll have to look closely to tell the difference, but the Volkswagen Jetta has received a raft of improvements for 2015, and nowhere is that clearer than with the TDI diesel model.
2015 VW Jetta
Look closely, kids – you're staring at the face of a refreshed Volkswagen Jetta. Yeah, it's hard to tell, what with the only noticeable changes consisting of slightly updated headlamps and taillamps, and some other aerodynamic tweaks. But the big news for the 2015 Jetta is what you can't see.
Volkswagen has offered up the lightest of refreshes on its Jetta for 2015, making subtle styling tweaks to the front, rear and interior while adding a few doses of new equipment. One of the biggest tweaks is the new, 2.0-liter TDI engine, which is now more efficient, returning 45 miles per gallon on the freeway (compared to 42 mpg on the 2014 model) while retaining the previous engine's 236 pound-feet of torque.
