Polestar 1 is a sleek, four-seat hybrid coupé based loosely on Volvo’s S90 executive saloon, but shortened by half a metre and armed with three electric motors and a two-litre, four-cylinder Volvo Drive-E engine, together delivering almost 600hp and 1,000 Nm of torque. Subsequent Polestars — a Tesla Model 3 rival and a larger SUV — will be fully electric.
