Styling cues and interior features distinguish the Sport models from S and SE variants. The Sport versions will have lowered suspension, unique alloy wheels and part-leather trim.
The S60 Sport has standard front foglights, rear spoiler and black mesh aluminium inlayed door trims.
The V70 Sport has load compensating suspension and is offered with a sports handling pack which includes speed-sensitive steering.
Jason King, forecasting editor of Glass's Information Services, said: 'The Sport specification within the premium brand sector has proven to be extremely successful and I believe the new additions to the Volvo fleet offering will be welcomed by drivers and fleet managers alike.
'The Sport models will definitely reinforce Volvo's brand positioning within the premium sector. Undoubtedly, it will attract a fresh audience to Volvo, particularly company car drivers looking for a dynamic car to match their personality and driving needs.'
Volvo will introduce Sport variants in the new S40 and V50 ranges shortly after their launch.
The S60 Sport starts at £21,395 OTR for the 2.0 T, while the V70 Sport starts at £23,678 OTR for the 140bhp 2.4-litre model.
