The GLI is not just a Jetta with more motor. It substitutes the standard car’s torsion-beam rear axle for a more-capable multilink rear suspension, giving the GLI a truly independent suspension that does an excellent job of managing body wobbles and transitions. Plus, the GLI is 0.6 inch lower than other Jettas, giving it a sportier stance and lowering the center of gravity.the new car is propelled by the GTI’s turbocharged four-banger mated to a manual or dual-clutch automatic, both with six speeds. With lots of low-end torque—at 1700 rpm, the peak of 207 lb-ft is just above idle—this is one of our favorite engines on the market today. As it does in the GTI, the iron-block 2.0-liter makes 200 hp. One thing the GLI has that the GTI doesn’t is a throaty, rumbly, and enticing exhaust note. Mash the throttle, and you’ll swear the sounds have to be coming from something other than such a small turbo engine.
