Running changes to the 2013 Volkswagen Beetle Turbo, Beetle Turbo Convertible and Jetta GLI include use of a new engine that is both more powerful and more fuel-efficient.
They'll be powered by VW's award-winning EA888 2.0-litre turbocharged and direct-injected TSI four-cylinder powerplant, which is now being produced in a new factory in Silao, Mexico.
The new engine is rated at 210 horsepower, up 10 horsepower from the previous Gen 2 TSI engine it replaces. Peak power is generated 200 rpm higher in the rev range, at 5300 rpm, and torque remains unchanged at 207 lb-ft.
With the new engine, the Beetle Turbo coupe is said to accelerate from 0-to-97 km/h (60 mph) in 6.6 seconds, which is 0.2 seconds quicker than the previous version.
The Jetta GLI takes 6.7 seconds for the same sprint, which makes it 0,1 seconds quicker with a manual transmission and two-tenths quicker with a DSG dual-clutch automatic gearbox.
The new engine also provides a manufacturer-estimated 4-to-8%improvement in fuel efficiency for the Beetle models, on the combined city-highway cycle, and up to % on the city cycle alone, the company says.
According to VW, he EA888 Gen 3 engine is designed to be lighter and more fuel efficient than the unit it replaces.
Engine mass has been reduced by almost 3% to just 132 kg.
Specific features of the engine include a thin-wall crankcase casting, exhaust headers that are integrated into the cylinder head, smaller diameter main bearings, roller bearings for its twin balancer shafts and a crankshaft with four counterweights instead of eight.
In addition to the new engine, the Beetle Turbo and Beetle Turbo Convertible get new R-Line bumpers with grained black surfaces, chrome-framed turn signals at the front and a diffuser at the rear. The Jetta GLI now LED taillights on all three trims.
The Beetle Turbo R-Line model is further differentiated by 19-inch "Tornado" aluminum-alloy wheels, R-Line badging, and Bi-Xenon headlights with LED DRLs.
These running changes take effect on 2013 models that go on sale this month.
