Volkswagen is rumoured to be already developing the next-generation Golf ahead of the model’s 2019 scheduled launch.

Innovative aerodynamic technologies for the next generation Volkswagen Golf

Said to mimic technical features of the XL1 model in order to reduce the average CO2 emissions, the next generation Volkswagen Golf is expected to sit just below 90 g/km. This is due to the European Union CO2 emissions restrictions that are set to come into effect in 2020.

Autocar is reporting that ‘given the need for such a significant reduction in average fuel consumption, VW engineers are unlikely to be able to just bet on another round of engine improvements. They will instead need to exploit every new trick in the book, including the most advanced aerodynamic treatment yet seen on a production vehicle.’

According to sources within the Volkswagen Group, a fundamental difficulty facing the engineers and designers is that, proportionately, the Golf is quite a short car. So a number of aerodynamic solutions are currently being investigated, and one possible solution, according to a VW source is ‘to extend the hatchback’s rear spoiler further over the rear window, along with deep blade-like extensions along the upright sides of the window.’

New Golf to be based on MQB platform

The Golf will also be based on the MQB platform which will provide the base and a targeted kerb weight of below 1100kg. There are also a number of technologies that are being discussed for implementation such as the Flywheel system which is already being tested by Volvo. The system can be used to power the rear wheels of a front-wheel-drive car, and can store waste energy and release it like an electric motor and battery.

Volvo’s system recharges from braking and offers 10 sec and 59 kW of drive assistance. If Volkswagen implements this system, it could provide the next generation Golf with up to 30 kW.

Another technology feature that is set to be implemented in the new Golf is the variable compression ratio engine which will be able to vary an engine’s compression ratio depending on the demands being placed on it which should then lead to significant advances in efficiency.

Coasting technology

Coasting technology will apparently be implemented into the Volkswagen range over the next few years and is expected to be rolled out in three stages. The first stage – coasting at speed – is already featured on some VW dual-clutch gearboxes. The last version will include transmission decoupling as well as engine shutdown while cruising at speed, traveling downhill or slowing down.

It’s also said that Volkswagen will make use of electric turbochargers which will be especially useful for downsized engines, which generate little exhaust gas energy, especially at low speed. This system blows air through the turbo when the engine is decelerating, spinning the turbo fan up to speed, so that full boost is available as soon as the driver gets back on the accelerator.

More details are said to be made available leading to the car’s official launch.
