Volkswagen Golf line-up now available to order with new efficient petrol engine

UK order books are now open for a raft of new ultra-frugal Volkswagen petrol models in the form of the Golf hatchback, Estate and SV.

Powered by a new three-cylinder, 1.0-litre 114bhp, turbocharged petrol engine, the new Golf TSI BlueMotion returns 65.7mpg on the combined cycle while emitting just 99 g/km of CO2.

Also available for the first time with a BlueMotion engine is the option of a DSG automatic gearbox. These cars combine the economy benefits of a diesel with the upfront price benefits of a petrol unit, with first deliveries due in September.

At the heart of the TSI BlueMotion is a 1.0-litre (999cc) three-cylinder turbocharged TSI engine from the EA211 series. This generates 114bhp from 5,000 to 5,500rpm, which results in a 0-62mph time of 9.7 seconds and a top speed of 127mph. With 200Nm, the TSI BlueMotion has the highest specific torque of any large-scale production series of petrol engines. This is available from 2,000rpm, though 150Nm is already delivered from just 1,500rpm.

Combined economy for the Golf hatchback is 65.7mpg with CO2 emissions of 99 g/km for both the six-speed manual and seven-speed DSG versions. Such economy is achieved through substantial engine development as well as a number of aerodynamic measures. The car also features super low rolling resistance tyres; when developing the seventh generation Golf, engineers made a 10 per cent improvement in aerodynamics.

Inside the engine, an ultra-rigid crankcase made of lightweight die-cast aluminum and its compact construction with three cylinders mean the 1.0-litre TSI is around 15kg lighter than a comparable four-cylinder engine. The exhaust manifold has been fully integrated into the cylinder head and fitted with a cooling jacket to make the best possible use of exhaust gas energy during the warm-up phase and to cool the exhaust gases even more effectively at high loads.

The TSI BlueMotion is also fitted with a toothed belt, which compared to a chain drive, reduces friction by around 30 per cent, while the maximum injection pressure of the 1.0-litre TSI is high for a petrol at 250 bar, while advanced five-hole solenoid injectors ensure precise fuel injections and results in faster energy conversion.

Unlike the diesel BlueMotion model, which is based on the entry-level S, the Golf TSI BlueMotion comes as standard in Match trim. It therefore benefits from equipment highlights including ESC, seven airbags, an Automatic Post Collision Braking System, a PreCrash system, cruise control, stop/start with battery regeneration and driver alert. The Golf Match TSI BlueMotion also comes equipped with 16-inch 'Dover' alloy wheels.
