World premieres of new drive systems were presented by Volkswagen recently. A progressive hybrid, and a diesel hybrid are the ones we will hear a lot more about.
Volkswagen tells us that it will be enhancing its model range by an innovative spectrum of completely new drive systems. These include affordable mild hybrid drives with 48V technology, and new high-tech diesel engines that will also be available as hybrid variants.
The technologies showcased as world premieres form a vital part of the progressively aligned Volkswagen drive strategy. It involves the combination of state-of-the-art petrol, diesel and natural gas engines (not for right-hand-drive markets), new hybrid systems and purely electric drives. With this combination, Volkswagen claims that it will among other things meet the CO₂ fleet emissions target of 95 g/km prescribed in the EU as of 2020.
New Golf to feature new hybrid system
The 48V mild hybrid is one of the most important new drive systems. Volkswagen will initially launch this variant on the market for the next Golf generation. With the new 48V technology, Volkswagen aims to make hybrid drives affordable to an extremely large clientèle.
The drive systems drastically reduce consumption and emissions while at the same time offering extra dynamism and comfort with an electric boost function and exceptional drive performance. Volkswagen will gradually extend the electrification of conventional drives to the entire fleet. The next Golf represents the starting point in this worldwide electric campaign.
New Diesel Hybrid
A new 2.0 TDI diesel engine (EA288 Evo) was announced and for the first time at Volkswagen, the Group’s TDI four-cylinder engines will also be available in conjunction with hybrid systems; the EA288 Evo will already start as a mild hybrid drive with 12V belt starter generator on its first use.
In conjunction with a lithium-ion battery, the mild hybrid system reduces fuel consumption and increases comfort. In general, what sets the new TDI engines apart is their extremely low emissions in all driving cycles. It goes without saying that they meet current and future emission stipulations for WLTP/RDE certification.
The output ranges from 100 kW/136 hp to 150 kW/204 hp. The TDI engines developed by Volkswagen will initially be used at Audi in vehicles with longitudinally installed drive train. The new TDI engines will also be used transversely in the MQB (modular transverse matrix) vehicles of Volkswagen and other Group brands in the future.
Volkswagen has also cut the CO₂ emissions of EA288 Evo engines by up to 10 g/km compared with the predecessor generation. As a result of said measures, these new TDI engines generate values below the limits laid down in current emissions legislation. Meanwhile, the power and torque values have increased by up to 9 percent.
