The Eterniti Artemis super SUV is the latest in a wave of luxury and sports crossover concepts to debut at the 2012 Beijing motor show.

But while the production models based on the Maserati Kubang, Lamborghini Urus and Bentley EXP 9F concepts are still months and years away, the Porsche Cayenne-based Eterniti Artemis is ready to hit the road.

The London-based start-up is taking orders for its high-performance Artemis SUV in London, Hong Kong and Taipei ahead of the first deliveries later this year.

Called the Hemera throughout its production, the renamed Artemis will have the power to keep up with its Bentley and Lamborghini rivals, and has a lavish interior that also promises to give them a run for their money.

The 4.8-litre twin-turbocharged Porsche-sourced V8 engine produces in excess of 441kW of power and 750Nm of torque, helping it storm from 0-100km/h in 4.5 seconds and push on all the way to 290km/h.

The car’s performance and handling have been developed by a race-bred British engineering team led by Alastair Macqueen – the man behind the Jaguar XJ220, which was the fastest road car at the time.

The Artemis retains the Cayenne’s body shape, but is differentiated by its hand-built carbon composite body panels, black mesh grille and intakes, tinted headlights, bonnet scoops, 23-inch alloy wheels, and unique rear with large diffuser, embedded tailpipes and vertical air outlets.

The limousine-quality interior is designed to be suitable for owners to both drive and be chauffeured in. Eterniti says drivers will enjoy the car’s on-road handling and off-road ruggedness and versatility, while passengers are treated with reclining seats, iPad holders, a drinks chiller, and materials of the finest quality including leathers, quilted carpets, lambswool, natural woods, piano black and carbonfibre.

The Eterniti Artemis is priced from £210,000 ($329,000) in the UK. There are no plans to bring the Artemis to Australia at this stage.
