New V6 powertrain delivers exhilarating performance

  • The lightest, most powerful, cleanest and most fuel efficient V6 turbo engine that INFINITI has ever offered
  • New ‘VR30 DDTT’ V6 provides potent and immediate power delivery, available with either 400 or 300 hp
  • Four-cylinder turbo-charged 2.0-liter gasoline engine also available

3.0-liter V6 twin-turbo engine

The all-new 3.0-liter V6 twin-turbo engine, from the new ‘VR’ powertrain family, is the most advanced V6 engine that INFINITI has ever offered, striking an ideal balance between drivability, efficiency, and performance.

The new engine, ‘VR30 DDTT’ was created through extensive in-house experience of six-cylinder powertrain development. The ‘VQ’ V6 powertrain family, predecessor to ‘VR’, has been a long-established and multi-award winning series of engines that has appeared in INFINITI models since 1994.

The compact and lightweight engine has been developed to deliver optimal power and torque for an engine of its size, as well as high levels of fuel efficiency. The engine is available with either 400 or 300 horsepower, with power and torque accessible across a broad spread of mid-range engine speeds in which drivers typically spend most of their time.

Peak power from the 400 hp engine (298 kW, 405 ps) arrives at 6,400 rpm, producing 475 Nm (350 lb-ft) torque at 1,600-5,200 rpm. With this engine, the Q60 will accelerate from 0-to-62 mph (0-to-100 km) in 5.0 seconds (AWD), and reach a top speed of 155 mph (250 km). With the highest power-to-efficiency ratio of any car in the premium sports coupe class, the Q60 is capable of 22 mpg (US combined, rear-wheel drive; 21 mpg all-wheel drive).

The 300hp engine (224kW, 304ps) produces its peak power also at 6,400rpm, and up to 400Nm (295lb-ft) torque across the same broad 1,600-5,200 rpm rev range. These outputs have been achieved while delivering 22mpg (US combined, rear-wheel drive; 22mpg all-wheel drive).

This balance of power to efficiency was made possible thanks to a set of newly-developed INFINITI powertrain features.

Chief among these is a new direct-injection gasoline (DIG) fueling system. The high-pressure DIG system allows for precise control over injection timings and the amount of fuel injected into the combustion chamber, delivering the exact amount required for smooth engine acceleration, depending on throttle position and engine speed. This system makes the new V6 one of the cleanest, most fuel efficient and powerful engines of its type that the sports coupe class has ever seen.

2.0-liter DIG engine

A four-cylinder turbo-charged 2.0-liter DIG (direct-injection gasoline) engine is also available on the Q60, with enhanced direct fuel injection for efficiency in all conditions. This engine delivers 208 hp (155 kW, 211 ps) at 5,500 rpm and 350 Nm (258 lb-ft) maximum torque from 1,500 to 3,500 rpm. A high-pressure direct injection with piezoelectric injectors delivers fuel to the engine in precise amounts for greater fuel efficiency: 25 mpg (US combined, rear-wheel drive; 24 mpg all-wheel drive).

The all-aluminum 2.0-liter turbo gasoline engine uses a hydraulic variable valve timing control system and direct fuel injection to maximize its mechanical efficiency, with resin-coated pistons minimizing friction. INFINITI’s Idle Stop-Start system, fitted as standard to 2.0-liter DIG engines, provides further improvements to fuel economy.

The engine’s wide-range single-scroll turbocharger provides peak torque at those engine speeds most commonly used by drivers, though the free-revving nature of the engine allows drivers to reach a red line of 6,300 rpm. Its DIG system, paired with a relatively low 9.8:1 compression ratio, allows the Q60’s 2.0-liter turbo engine to offer similar performance characteristics to the new, larger 3.0-liter twin-turbo V6 engine.
