Car and Driver is reporting the Lamborghini Huracan and the Audi R8 could receive a 5-cylinder 2.5-liter turbocharged and supercharged engine.

According to e new report from the magazine, big engine taxes in Asian have prompted Volkswagen Group to consider offering a smaller turbocharged unit for the Huracan and the R8 supercars in China. Currently available exclusively with naturally aspirated V10 motors, both vehicles could get the 2.5-liter TFSI engine from the Audi TT Clubsport Turbo concept. It benefits from an electric turbo and generates 600 PS (441 kW) and 650 Nm (479 lb-ft) of torque.

“Electric boosting would be necessary for any smaller motor, even if it’s turbocharged,” Quattro GmbH’s head Heinz Peter Hollerweger commented. “The problem with electric boosting is that this type of battery is much heavier and the weight disadvantage of the battery has to be countered by the performance gain.”

Audi doesn’t seem to be interested in smaller engines for the R8 at all, as previously it explained weak demand for the V8 engine forced the manufacturer to drop it from the current generation of the model.
