Volvo S90, V90 and XC90 models are now available with a more potent T5 petrol engine.
The 2.0-litre four-cylinder unit is turbocharged and produces 250PS.
In the S90 saloon, the T5 engine emits 154g/km of CO2.
With prices starting at £41,120 for the R Design model, company car drivers will pay £5,000 a year in Benefit-in-kind (40% taxpayer).
The T5 is the most powerful non-hybrid in the line-up, giving the S90 a 0-62mph acceleration time of 6.8 seconds.
In the V90 it achieves 41.5mpg and 157g/km, and from 38.2mpg and 172g/km with all-wheel drive in the Cross Country.
Prices start at £43,120 for the V90 T5 R-Design and £44,685 for the V90 T5 Cross Country.
In the XC90 SUV, the T5 with all-wheel drive costs from £50,435 in Momentum specification.
The XC90 T5 AWD achieves 35.8mpg and 184g/km, while acceleration to 62mph takes 7.9 seconds.
Benefit-in-kind tax for the XC90 T5 costs around £100 per year more than the less-potent D5, although the T5 uses more fuel.
Jon Wakefield, managing director of Volvo Car UK, said: "The T5 petrol engine is a superb addition to the S90, V90 and XC90 ranges. This cutting-edge engine brings increased choice for our customers, and offers strong performance with excellent efficiency and refinement. We're sure it'll be a hit with retail and business users alike."
