At launch in North America, two advanced powertrains will be available, followed by additional engine options in other global markets later in the year. The Q50's refined 3.7-liter aluminum-alloy DOHC 24-valve V6 is rated at 328 horsepower and 269 lb-ft of torque and features Continuously Variable Valve Timing Control System (CVTCS) and Variable Valve Event & Lift (VVEL®).

The available hybrid powertrain features the Infiniti Direct Response Hybrid™system with Intelligent Dual Clutch Control. It combines a 3.5-liter 24-valve DOHC aluminum-alloy V6 and compact laminated lithium-ion battery design with an innovative one-motor/two-clutch motor control. The system's V6 is rated at 296 horsepower and 255 lb-ft of torque, while the advanced 50 kW electric motor is rated at 67 horsepower and 199 lb-ft of torque. The hybrid system net power is 354 horsepower, providing strong acceleration and lean fuel economy.

"True to the Infiniti DNA, our hybrid powertrains put performance first, without compromising fuel efficiency. It takes full advantage of the electric motor's instant torque for exceptional acceleration and, in combination with the 3.5-liter V6, provides a sporty driving feel under all driving conditions. We have targeted the best balance of performance and fuel economy and hit it dead center," said de Nysschen.

Both Q50 powertrains are matched with an advanced 7-speed electronically controlled automatic transmission with manual shift mode and available steering column-mounted magnesium paddle shifters. The Q50 is available in rear-wheel drive and Intelligent All-Wheel Drive with both powertrains.

Precise handling is provided by the 4-wheel independent multi-link suspension. The front is a single pivot double-wishbone design, while the revised rear design utilizes a multi-link design with coil springs and Dual Flow Path® shock absorbers, with increased camber stiffness and improved ride comfort. The suspension features extensive use of lightweight aluminum components, along with front and rear stabilizer bars. A sport-tuned suspension is available with Sport models. Also supporting the enhanced handling is an improvement in front body stiffness (versus the previous generation).

The Q50 rides on 17-inch aluminum-alloy wheels with machine-finished surface with 225/55R17 all-season run-flat tires. Also available are 19-inch aluminum-alloy sport wheels with 245/40R19 run-flat all-season or summer tires. Confident braking is provided by 4-wheel power-assisted vented disc brakes with 4-wheel Anti-lock Braking System (ABS), Electronic Brake force Distribution and Brake Assist. Also available are sport brakes with upgraded rotors, 4-piston front calipers and 2-piston rear. Steering is provided by a power-assisted vehicle-speed-sensitive rack-andpinion system.

The new Q50 also features available Infiniti Direct Adaptive Steering technology, a world's first production vehicle design. The system allows independent control of the Q50's tire angle and steering inputs, transmitting the driver's intentions to the wheels faster than a mechanical system.

This increases the direct driving performance feel by quickly and intelligently communicating road surface feedback to the driver. Four different steering settings are offered, allowing customization by driver preference or road conditions. This world's first technology provides the flexibility for the driver to change both steering effort and the steering gear ratio. A backup mechanical steering system is provided with models utilizing the new Direct Adaptive Steering technology.

Also offered is another world's first, Active Lane Control, which uses a camera-based straight-line stability system to further enhance on-center driving capability and improve vehicle stability. The system is included as part of the Lane Departure Prevention system, not only adjusting for unintended lane drift, but also making finer adjustments for minor road surface changes or crosswinds (as detected by the camera-based, lane marker detection system). The system goes beyond the traditional Lane Departure Prevention system, taking it a step further by not only reading the road ahead (the camera is located above the rearview mirror) for unintended lane drift but also by making small steering input angle adjustments if the Q50 undergoes minor direction changes due to road surface changes or crosswinds (as detected by the lane marker detection system). By reducing the need for steering input for the driver, the driver's effort may be reduced.
