Sitting under the bonnet of both the 2016 Infiniti Q50 sports sedan and the 2017 Q60 coupe is Infiniti’s new 3.0-liter twin-turbo V6, codenamed VR30, and they have announced the start of production at the Iwaki plant in Japan.
This new engine was developed by Shosaku Ando, chief powertrain engineer, to be the lightest, cleanest, and most powerful and fuel efficient V6 engine that Infiniti has ever offered to the global market. Only Q60 Coupes with the Red Sport performance trim will be equipped with this engine and it will produce an output of 400hp and maybe around 350 lb-ft of torque, similar to that of the Q50.
Pushing the turbocharger’s turbine speed up 10% to 220,000rpm is a bespoke turbine speed sensor along with an updated turbine blade design and keeping the induction temperatures in check is a second water pump in the cooling circuit.
Not only is the horsepower impressive but so is the technology built into this engine. According to AutoGuide, these features include “integrated exhaust manifolds ensure its catalysts fire off quickly and help the engine warm up in frigid temperatures, gasoline direct injection cuts fuel consumption, electrically actuated variable valve timing responds quicker than hydraulic systems and is more efficient, the cylinder walls even have a thermal-arc spray treatment, which results in a “mirror bore coating” that reduces piston friction by 40 percent.”
The first model to get this new engine will be the Q50 and the Q60 Red Sport will come after that though no specific date has been released.
