Volkswagen Jetta Getting New 1.4L Turbo Four
5 Août 2015 - Autoblog
In yet another example of engine downsizing, Volkswagen has announced it is slotting a new 1.4-liter turbo four into the Jetta.
The smaller, forced-induction engine will replace the naturally aspirated 2.0-liter four in the Jetta S and the 1.8-liter turbo four in the Jetta SE, bringing with it direct injection and improved fuel economy.
The 1.4-liter turbocharged four-cylinder engine is from the EA211 family. It's made of aluminum and features a compact single-scroll compressor, an intercooler integrated into the injection-molded induction pipe, exhaust manifold integrated into the head, variable intake and exhaust valve timing, direct fuel injection, dual overhead cams driven by a toothed belt, and a 10.0:1 compression ratio.
All that adds up to 150 horsepower and 184 pound-feet of torque, mated in the Jetta to either a five-speed manual or six-speed automatic transmission. Fuel economy figures have yet to be certified, but are projected to come in at around 39 miles per gallon on the highway with the automatic, representing 13- and 7-percent improvements over the units it replaces.
The EA211 is Volkswagen's new global small gasoline engine family, manufactured principally by Škoda in the Czech Republic. It's set to replace the old EA111 series, offering higher efficiency in a more compact and adaptable package. The Jetta Hybrid already uses essentially the same engine paired with an electric motor, and is being adapted to three-cylinder formats as well.
