Next-generation Volkswagen Golf to Offer Electric Assist, but Just a Tad

Audi is bullish on 48-volt mild hybrids, and its Volkswagen sister division is no different in wanting to see larger batteries take some of the load off of its internal combustion powerplants.

The automaker announced Thursday that its upcoming eighth-generation Golf will offer a low-cost alternative to purely gas- or diesel-powered motoring. The mild hybrid system appearing on that vehicle, due next year as a 2020 model, will soon spread throughout the VW lineup, the automaker claims.

VW’s 48V system also works with diesel engines, which should give stringent European regulators something to smile about (and perhaps extend the longevity of an engine type with a soiled reputation).

Like other belt-driven starter generators, the system allows for easy stop/start functionality, with electric power transferred to the engine’s crankshaft via the serpentine belt during acceleration. Think of it as a light electric boost. While the small battery (in hybrid terms) isn’t capable of propelling the vehicle under electric power alone, VW claims it allows for gas-free coasting on the highway, furthering the system’s fuel economy benefits.

The 48V battery replenishes itself through regenerative braking, just like a conventional hybrid.

The automaker calls the new mild hybrid a “starting point” in its quest to spread electrification through its model lineup. Don’t worry — VW didn’t neglect to mention there’ll be “extra dynamism” available in the new car, all thanks to this gas-saving feature.

As VW Group hasn’t given up on diesel just yet, the company also previewed a new 2.0-liter TDI four-cylinder yesterday. The engine’s targeted at front- and rear-drive Audi applications, but don’t hold your breath waiting for it to arrive on these shores. Output ranges from 136 horsepower to 204 hp. As mentioned earlier, it’s available in mild hybrid guise.

The quintessential fun hatch, VW’s Golf stands to see a styling revamp when the new model rolls off the line next year. While it’s expected to borrow some cues from 2015’s Golf GTE Sport concept (like the flagship Arteon), you’ll surely be able to pick it out from a crowd. Messing with the Golf is like messing with the Jeep Wrangler. Go too far and you risk offending the faithful.
