Polestar may revert to using smaller engines in its latest models as part of adopting Volvo’s new strategy to employ more efficient four-cylinder mills across its range. However, according to AutoExpress, the tuning company’s specialities may offer up to 450 hp despite downsizing its powertrains.

Currently, Polestar models like the S60 and V60 feature 3.0 litre six-cylinder T6 petrol engines. These deliver 345 hp and 500 Nm of torque from the off. The publication says that it tested a 450 hp Polestar prototype in 2014, and believes that future performance models from the Swedish brand could get just that.

The 450 hp engine in question is a highly-tuned 2.0 litre four-cylinder mill, likely based on the brand’s current Drive-E engine. “It is one way of Volvo saying that the current powertrain line-up has potential to grow,” said Volvo powertrain manager Olle Fast.

T6 AWD with Polestar Performance Optimisation

In its highest state of tune, the current T6 Drive-E engine in the Volvo XC90, S90 and V90 offers 320 hp and 400 Nm of torque. In hybrid T8 Twin Engine variants, power is taken up to 407 hp and 640 Nm. Based on this understanding, it would take something special from Polestar to develop 450 hp on petrol power alone.

It could be then that, as previously reported, Polestar may turn to hybrid power in its future models. “Volvo is a big producer of plug-in hybrids. We work a lot with plug-in hybrids so we would go into a different road than the other brands,” said Volvo product manager Lars Lagstrom when he was quizzed on the subject in August last year.

No further claims were made by the publication based on the coming Polestar performance models, other than that they will appear first on the next-gen S60 and V60 models. We can’t say for sure if that’s the case, given that Polestar versions of the already-unveiled XC90, S90 and V90 are equally likely.
