The world's fastest Volkswagen Beetle set a new land speed record at the World of Speed at the Bonneville Salt Flats in Utah, America, last week.

During the record attempt on 12 September the Beetle reached an average of 330kph across a one-mile stretch – with a maximum of 335kph achieved.

The car features the same turbocharged 2.0-litre four-cylinder powertrain as the 2014 Turbo R-Line model, but it has had a complete overhaul to boost power from 207hp to 535.5hp, with a peak torque of 571Nm.

Labelled the Beetle LSR (Land Speed Record), the car was modified by California’s THR

Manufacturing. The car was has uprated turbochargers and pistons, as well as other changes including modified suspension for a lower stance and a front air dam to help control air flow.

Modifications need to be in line with official speed record rules, so extensive changes to the exterior allowing for more aerodynamics were not permitted. The Beetle was also equipped with special wheels, complete with high-speed racing profile tyres that were suitable for driving on salt.

A limited-slip differential was also used to improve traction, while a safety package provided the necessary driver protection, including a roll cage, a new racing bucket seat with five-point harness and a fire extinguishing system.

The record-setting car also had two brake parachutes that were used to slow down the Beetle.

The record was officially recorded at the event sponsored by the Utah Salt Flats Racing Association (USFRA), and was set with Automobile Magazine's contributing editor, Preston Lerner, at the wheel.
