The updated Volkswagen Touareg will go on sale later this month, with prices starting at £43,000.
Revealed at the Beijing motor show earlier this year, revisions to the SUV focus on economy, with slow-selling V8 and hybrid versions dropped from the range.
Although V8 diesel and hybrid powertrains will no longer be offered, Volkswagen has retained the 201bhp 3.0-litre V6 TDI and has boosted power for the 242bhp version to 258bhp.
Myriad revisions have been carred out to improve efficiency, including the fitment of low-rolling resistance tyres and stop-start and battery regeneration systems. Both engines are EU6 compliant thanks to a new catalytic converter option that uses AdBlue to reduce emissions.
Volkswagen claims that 201bhp versions return 42.8mpg on the combined cycle and emit 173g/km of CO2, while the 258bhp version records 42.8mpg and 174g/km. Previously, those engines returned 34.4mpg and 33.6mpg respectively.
The 2015 Touareg features larger Bi-Xenon headlights fitted across the range, a new larger grille and a reprofiled bumper. At the rear a new bumper and diffuser is fitted. Other additions include a new range of alloy wheel designs, paint colours and shades of leather upholstery.
