But if you want to have the privilege of owning the very first new XJ off the production line – a 3.0 litre diesel Portfolio worth £62k – you can enter a competition Jaguar are running to give away that very first car. Jaguar are hoping that sales of tickets for the competition – which cost £125 each – will raise £1 million for the NSPCC’s ‘Child’s Voice’ appeal, which is aiming to raise £50 million in total to fund its helplines.

AutoWeek office swag: Mazda rotary-engine keychain with realistic motion

When I got the keys to our long-term 2011 Mazda 5 last week, they came with a surprise--this aluminum-and-brass keychain in the shape of a rotary-engine housing, complete with moving rotor. The rotor doesn't just rattle around or spin in a circle. Thanks to a thumbwheel on the back of the housing, coupled with a timing gear and offset crank journal, the thing actually moves in an approximation of epitrochoidal motion just like a real Wankel.

BMW 7-series hybrid due in 2009

By Nick Gibbs Motor Industry 07 July 2008 14:30 BMW will launch a hybrid petrol version of the newly unveiled 7-series in 2009, but admits it’s more for green-leaning V8 addicts than seriously eco-aware bosses. Even with the latest lithium-ion batteries, the forthcoming 4.4-litre V8 petrol-electric version will struggle to match the astonishing 39.2mpg and 192g/km of CO2 of the new six-cylinder diesel, especially when BMW will launch stop-start technology for the whole range within two years. The hybrid is likely to cost several thousand more than the £65,000 it’s estimated you’ll need to buy the regular, twin-turbo 750i that goes on sale in November 2008.
