Volkswagen may say this is a near-production version of the Jetta, but there’s a massive power gap between the road-going car and this custom vehicle built to tackle Utah’s salt flats. The vehicle available in showrooms has to make do with 147 horsepower from a 1.4-liter engine whereas this one has nearly three and a half times more oomph. That’s right, the 2.0-liter TSI four-cylinder gasoline unit belonging to the familiar EA888 engine family has been tuned to deliver “significantly more” than 493 hp (or 500 PS as per the press release).

The good news is a hotter Jetta GLI – upon which the Bonneville car is based - is right around the corner and is set to use a “similar engine with a slightly more demure power rating.” That being said, don’t expect the 2.0 TSI to develop anywhere near the 493-hp output of what VW hopes to be a record-breaking car. The spicy version of the popular compact sedan will utilize just about the same engine configuration found in the U.S.-spec Golf GTI, so we’re looking at somewhere in the region of 220 hp (164 kW) and 258 lb-ft (350 Nm) of torque.

Update

 

When can we expect to see the Jetta GLI? VW promises it “will soon be taking off in the U.S.,” whatever that means. Since the folks from Wolfsburg have said the new-generation Jetta won’t be offered in Europe because it’s too big, it will be a similar story with its sporty derivative. Other tidbits known about the Jetta GLI include the availability of an optional seven-speed dual-clutch gearbox as an alternative to the standard six-speed manual, along with an independent rear suspension sourced from the Golf GTI to replace the regular Jetta’s cheaper torsion-beam arrangement.

Meanwhile, between August 11 and 17, the purpose-built Jetta Bonneville will attempt to surpass 208.572 mph (335.5 km/h) in order to set a new record in the BGC/G class of the Southern California Timing Association on Lake Bonneville. VW has already taken down two important records this year with its electric race car at Pikes Peak and at the Goodwood Hill Climb.

Volkswagen aims to break the land speed record on the United States salt flats with its new Jetta

  • The record-breaking car is based on the new Jetta GLI and is expected to reach a speed of more than 335 km/h
  • After the success of the I.D. R Pikes Peak, the Jetta is set to tackle the third record in three months

Volkswagen is still on the hunt for new records: only a few weeks after the success of the electric I.D. R Pikes Peak in the “Race To The Clouds” held in the Rocky Mountains and in the UK’s Goodwood Hill Climb and it’s already time for the next sporting highlight. Between 11 and 17 August, Volkswagen of America will be aiming to break the land speed record in the BGC/G class of the Southern California Timing Association on Lake Bonneville – the salt flats in the US state of Utah – with its specially prepared but near-production version of the new-generation Jetta1.

 

This Volkswagen is powered by a four-cylinder turbo engine (TSI) from the EA888 engine family with a power output of significantly more than 500 PS. A similar engine with a slightly more demure power rating will also be used in the new Jetta GLI, which will soon be taking off in the US. Engines in this high-torque series are used to power vehicles including theGolf GTI Performance2 (169 kW / 230 PS) and the Golf R3 (228 kW / 310 PS). On Lake Bonneville, the TSI engine must accelerate the modified Jetta to more than 208.572 mph (335.5 km/h) to equal the existing record for a car in this class. To get an idea of the speed: racing cars on the legendary Hunaudières track battle it out at speeds of 340 km/h in the “24 Hours of Le Mans”. Hinrich J. Woebcken, President and CEO of Volkswagen of America: “With this attempt at the record we want to underline the sporting potential of the new Jetta and inspire our customers with the more powerful Jetta GLI.”

The record-breaking car can reach a speed of more than 335 km/h as it is very light (the interior comprises only the controls for driving, a bucket seat with racing belts and a roll cage) and has excellent aerodynamics (Cd value: 0.27) As in the case of the I.D. R Pikes Peak – with which Volkswagen set the new record for the Pikes Peak International Hill Climb (Race To The Clouds) in the US on 24 June and then left the record for electric vehicles in the dust in the Goodwood Hill Climb at the Goodwood Festival of Speed in the UK on 9 July – the aerodynamics also ensure a very high downward thrust. This factor is essential in making sure the Jetta stays safe on the salt flat track, even at extreme speeds.

The Jetta, developed by Volkswagen of America in cooperation with the Bonneville specialists at THR Manufacturing in Ventura, California, has further technical refinements on board: in addition to a very low chassis, these include special salt flats wheels and tyres, a limited slip differential for optimum grip and two brake parachutes in the rear end. The specially developed Bonneville graphics on the body were contributed by Volkswagen's Southern California Design Center. “We wanted to emphasise the technical charisma of the Jetta and give the car designer graphics that set it apart from the extraterrestrial-looking environment of the Bonneville Salt Flats,” says Reto Brun, Director of the Design Center.

If the attempt succeeds, this Jetta will be the fastest near-production Volkswagen ever to be put on wheels. This record is currently held by a 399 kW / 543 PS Beetle LSR, which – also powered by an EA888 engine – reached a speed of 205.122 mph (330.11 km/h) on Lake Bonneville.
