Hot crossover looks to be in line for electrical assistance, potentially taking its total output north of 150kW.
Ford looks to be testing a hybrid version of its hot Puma ST at the Nürburgring, which means a more efficient yet more potent powertrain option could be on the cards.
The car was spotted with ST-Line badging but sported several of the design features bespoke to the full-fat ST, including its unique alloy wheels, bumpers and red brake calipers.
The yellow sticker on the rear windscreen indicates a hybrid element in the powertrain. There was no charging flap on display, ruling out the possibility of a plug-in powertrain. That means the model undergoing tests was either a full-hybrid or mild-hybrid set-up. The latter is more likely, given the Puma is not offered with the 2.0-litre engine common to all full-hybrid Ford models.
The standard Puma is currently sold with a mild-hybridised 1.0-litre Ecoboost triple producing 92kW, but the Puma ST is not yet available with an electrified powertrain.
The model currently offers 147kW, so a move to hybrid power would be likely to push the model over the 150kW barrier while delivering improved economy figures.
The performance crossover is already set to receive a hybrid powertrain in a motorsport capacity in line with new World Rally Championship regulations in 2022, which will see all competing cars equipped with hybrid engines.
Ford’s new Puma-based WRC racer, built in partnership with Cumbria-based racing and motorsport engineering firm M-Sport, was revealed at this year’s Goodwood Festival of Speed and is driven by a 1.6-litre turbocharged engine mated to a 100kW electric motor, producing far more power than the road-going version.
