The petrol-electric set-up is essentially the same one that has already been seen in the latest Porsche Cayenne and Panamera. It comprises a 335bhp turbocharged 2.9-litre V6 mated to a 134bhp electric motor that sits between the engine and the eight-speed Tiptronic automatic gearbox and is powered by a 14.1kWh battery mounted beneath the boot floor. Combined power output is 456bhp, while total torque is a muscular 516lb ft.
“Using this drivetrain was a bit opportunistic,” explained Capito. “With the relatively low volumes that R achieves, we can’t develop a standalone hybrid system, so we have to look around for what’s already available in the [Volkswagen] Group. If we do a car that can’t be built on the existing line, the price goes way up. This is why I love working for R, because I can deliver cars that are for people who love driving yet are also affordable.”
As you would expect, there are numerous hybrid-related settings. Among them is E-Mode, which allows electric-only driving at speeds of up to 87mph before the V6 kicks in. It also fires up when you request kickdown by fully opening the throttle.
When the battery is running low, it’s possible to set the level of charge that you desire, which the system then achieves by using the V6 as a generator and increasing the level of regenerative braking.
To enable the Touareg to maintain its off-road prowess and 3.5-tonne towing weight (around 80% of customers tow with their Touaregs), the R model retains the Torsen-equipped four-wheel drive transmission with various on- and off-road driving modes. Unlike the Golf R and T-Roc R, however, it has no Race mode. In normal running, up to 80% of the engine’s torque can be sent to the front axle and up to 70% to the rear axle.
As with the regular Touareg, customers will be able to order an Off-Road Package complete with improved underbody protection and extra traction control settings for driving on gravel, mud and sand.
The regular Touareg’s air springs and adaptive dampers are also retained, unusually with no alterations made to either hardware or software. “We didn’t feel we needed to make any changes,” Capito explained. “The standard set-up is good and we wanted to retain the car’s everyday usability. This is a car that will have to do everything”.
The need to package a bulky battery above the rear axle means the Touareg R isn’t available with neither the 48V active anti-roll bars that are optional on other models nor the four-wheel steering system. However, Capito revealed that these systems would likely be incorporated into a future facelifted model.
