Audi’s new 4.0-liter turbocharged V-8 is quite the engine. Case in point: the 4.0-liter is now being used at Bentley. For the first time the Continental GT has added eight-cylinder power as an option, after sticking with twelve-cylinder power for its life span.
The 4.0-liter V-8 packs a horsepower punch, and it is slated to play an important role in premium vehicles at the Volkswagen Group. Automotive News reports that a modified version of the engine could do duty in the Lamborghini Urus.
When it debuted, many were thinking the crossover would pack a huge 10 or 12-cylinder, like the rest of the Lamborghini. To meet targets for weight and dynamics performance though, that may be ruled out.
Maurizio Reggiani, Lamborghini director of Research and Development, says: “We were given a very challenging target: Make the production Urus the best-performing and lightest vehicle in its category. This is forcing us to think outside the box…..as the unibody structure of the PL73 is made of steel, we need to think of innovative solutions so we can meet the very challenging weight target we were given.”
PL73 is the platform underpinning the Urus, and it will be shared with the Audi Q7, Bentley SUV, Porsche Cayenne and Volkswagen Toureg. The weight target for the Urus is 4,400 pounds, AN says that is “440 pounds lighter than any of the models it would challenge if launched today.” We aren’t sure what those models are exactly (we assume it is referencing vehicles like the BMW X6), but OK….
A heavy use of composite materials, magnesium and aluminum will likely be used to achieve that goal. Weighing in favor of a V-8 is a compact, lightweight design. “Such a car needs huge torque at low revolutions rather than high peak power, therefore a V-8 twin-turbo is an interesting possibility,” Reggiani says.
The official line is that Lamborghini is waiting on approval for the Urus SUV, but it is as good as done. It’ll be a while before it shows up though: Reggiani says “no sooner than early 2017.”
