VW Polo G40 widebody from the 80s: supercharger instead of compromise

While many manufacturers turned to turbochargers, VW took a different approach: With the G-Lader, they developed their own compressor, which was driven directly by the engine. The idea: pressure buildup without delay. Thus, no turbo lag, which was typical of turbos of that era.

The VW Polo G40 featured a 1.3-liter four-cylinder engine, which, thanks to the G-charger, produced 85 kW (115 hp) – with a curb weight of around 850 kilograms. This results in a power-to-weight ratio of 7.4 kg/hp – a figure that catapulted it into the league of compact sports cars of the time.

But the G40 wasn't just an engine experiment. VW Motorsport also offered a widebody kit for the Polo Coupé, sharpening both its looks and technical specifications. Widened fenders, new bumpers, front air intakes, and a rear spoiler package – everything was designed to translate the increased performance into driving dynamics.

The conversion cost approximately 8,500 Deutschmarks and could also be purchased as an aftermarket upgrade from a dealer. The track was widened, larger wheels were possible, and the aerodynamics were adapted to motorsports standards.

The Polo G40 wasn't just used on the road; it also served as the basis for the VW Polo Cup cars. Future DTM and rally stars gained their first experience in this junior racing series. The production G40 proved surprisingly close to the Cup cars: the same engine, similar layout, but with clear motorsport DNA.

At the same time, the G40 remained surprisingly accessible in everyday life: not a tough race car, but a drivable compact sports car with decent manners. It's precisely this balancing act that makes it so appealing to technology fans to this day.

While the G40 went into production in 1987, the widebody remained a rarity. Only around 100 examples are said to have been delivered or converted with the complete motorsport kit – most through select VW dealers or directly through the motorsport department.

Today, these vehicles are true collector's items. Their technical condition is often critical: Even back then, the G-Lader was considered maintenance-intensive and sensitive. Regular overhauls were required. Anyone who finds an original G40 widebody in good condition today is dealing with one of the rarest Polo derivatives ever.
