The XC40 is the first car available from the scheme.
The service offers complete end-to-end service, from vehicle specification right through to the final purchase agreement. Customers using the service can go through every part of the buying process from speccing powertrain and colour options, to choosing accessories.
Volvo says the entire process of buying a new car can take as little as 20 minutes, and there are multiple checks built into the process to protect buyers.
Users of the service can also tailor their finance options, whether it's a personal contract purchase (PCP) or personal contract hire (PCH) agreement, a conditional sale or an all-out cash purchase. Part-exchanges can even be arranged on the service.
Customers can see in real time how their finance choices are impacted by things like changing the colour, adding options or packs, or adding accessories such as a dog harness.
"Whether online or offline, the way people buy cars has changed," said Jon Wakefield, Volvo Car UK Managing Director. "Customers now have much more control over the process, and Volvo Online helps them to take that one step further."
"It makes life as easy as possible without compromising on choice or security, and lets customers drive the purchase process when it’s most convenient for them."
The only car available on Volvo Online at the moment is the XC40 crossover, but other models will be made available by Friday May 3. It will strengthen the relationship between the customer and their local retailer, which will manage the entire process to help customers choose the right car and finance package for their needs.
The service's launch has come at a good time for the Swedish brand, which has enjoyed a 39 percent rise in sales for the first three months of this year.
