The new package means fleets running BMWs will have access to five years/60,000 miles of maintenance-free ownership for a fixed fee.
The scheme now includes models such as the Z4, X3 and X5 alongside the BMW 5-series, 6-series and 7-series which are already included in the deal.
Prices for the package include £950 for the Z4, £1,000 for a 5-series, £1,200 for an X3 or X5 or £1,250 for a 6-series or 7-series.
A BMW spokesman, said: 'We have introduced the Service-Inclusive package to standardise things. It makes ownership easier and makes costs easier to budget for.'
The group has also extended its online package for the 5-series. For an initial fee of £450 and an annual fee of £120, fleets can access BMW's mobile internet portal on the vehicle's iDrive controller.
The spokesman said; 'This is an added bonus with the iDrive. If a company car driver is doing 50,000-miles a year, it makes business easier. They are able to access information such as hotels, restaurants and local car parks.'
The online package also provides access to news and weather reports and a directory inquiry service, all displayed on the standard fit display screen.
