The BMW X6 hybrid has been caught testing in California ahead of its Detroit introduction
3 July 2008

Our spy photographers have caught BMW’s new X6 hybrid being tested in California ahead of its official unveiling at the Detroit Motor Show next year.The technology was previewed at last year with a concept at the Frankfurt show, the BMW X6 ActiveHybrid concept. Developed with General Motors and Daimler, the system uses two high-performance electric motors connected to each other by three planetary gear sets. These work in conjunction with a CVT transmission delivering power from the engine – reported by insiders to probably be a version of BMW’s familiar 3.0-litre straight six petrol motor.The ActiveHybrid system also allows the car to be driven on electric power or the combustion engine alone, or with a combination of the two. A brake regeneration system similar to that already in use on some of BMW’s other models is also present, allowing the traction motors to recover energy while slowing down for storage in the onboard battery pack.Fuel consumption is expected to be reduced be 20 per cent compared to a conventional model: these savings on top of those already delivered by BMW’s Efficient Dynamics system.Despite the recent BMW X5 Vision concept previewing a diesel hybrid system, a petrol engine suits the BMW X6’s ‘sports’ appeal and will also sell better in North American, which will be the car’s biggest market. Expect UK sales to start in summer 2009.

Our Verdict

BMW X6
The BMW X6 has challenging looks but impressive dynamics. It is good value too

The BMW X6 is a hard riding but generally accomplished big soft-roader. Just make sure you can live with the looks

    First Drive
    16 October 2017
    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq
  • Audi Q7 e-tron
    First Drive
    16 October 2017
    Expensive and flawed but this understated diesel-electric Audi Q7 has a lot to offer
  • Citroën C3

    Is the third gen Citroën C3 ‘fresh and different’ enough to take on its supermini rivals? We spend six months with one to find out
  • BMW X3
    First Drive
    15 October 2017
    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again
  • Vauxhall Insignia Country Tourer
    First Drive
    13 October 2017
    Off-road estate is now bigger, more spacious and available with torque-vectoring all-wheel drive, but is it enough to make its German rivals anxious?
