Volkswagen has expanded its TDI line-up with the arrival of the Phaeton and Touareg V6 TDI models, both using a new 3.0-litre six-cylinder engine.

The new 2,967cc V6 turbodiesel features four valves per cylinder and piezo electric injector technology. With this system, up to four fuel injections per cycle are possible, for better emissions control. Both the Touareg and the Phaeton V6 TDI feature Volkswagen’s new DPF (Diesel Particulate Filter) – the first Volkswagens to use this technology in the UK.

The new engine joins the most powerful production diesel engine to date, the 5.0-litre V10 TDI, in the Phaeton’s diesel line-up.

The Phaeton comes with sophisticated 4Zone climate control, CDC air suspension and xenon headlights as standard. The Phaeton delivers 29.4 mpg on the combined. The Phaeton V6 TDI starts at £41,040 on the road for the five-seat model, going up to £46,495 for the four-seat version.

With the arrival of the V6, the number of TDI diesels in the Touareg 4x4 range increases to three. The Touareg V6 TDI costs £34,200 RRP on the road, with the Sport version adding £1,070. Both vehicles are available to order now.
