Empowering performance from innovative technology

The Q60 sports coupe has been engineered to deliver a truly engaging sports coupe experience as standard, offering a unique balance of ride comfort and agile handling that has become synonymous with the Infiniti brand. Enhancing this position, the Q60 has been fitted with a range of new and innovative driving technologies to deliver empowering performance and a personalized experience behind the wheel.

Powertrain

New V6 powertrain technology delivers exhilarating performance

The new range of engines available in the Q60 complements the direct and agile ride and handling characteristics of the premium sports coupe for an exhilarating drive. Three power units are available – and all offer instant power delivery, smooth responses to driver inputs, high performance output, and mechanical efficiency.

The all-new 3.0-liter V6 twin-turbo engine, from the new ‘VR’ powertrain family, has been developed to deliver optimal power and torque for an engine of its size, alongside greater fuel efficiency. The high-output version of the V6 delivers 400 hp (298 kW, 405 ps) at 6,400 rpm and 475 Nm (350 lb-ft) maximum torque at 1,600-5,200 rpm; while the 300 hp (224 kW, 304 ps) version (at 6,400 rpm) produces 400 Nm (295 lb-ft) torque at 1,600-5,200 rpm.

These outputs have been achieved while delivering efficiency: 23 mpg (US) and 154 g/km CO2 (estimated) for the 300 hp version, and 22 mpg (US) and 206 g/km CO2 (estimated) for the 400 hp model – with the latter offering one of the best power-to-efficiency ratios in the premium sports coupe class.

This power-to-efficiency performance was made possible thanks to a set of newly-developed powertrain features, including an advanced new twin-turbo system which enables smooth and immediate responses under acceleration, while aiding efficiency.

A four-cylinder turbo-charged 2.0-liter gasoline engine is also available on the Q60, with enhanced 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 at 1,500 rpm. A high-pressure direct injection with piezoelectric injectors delivers fuel to the engine in precise amounts for greater fuel efficiency – 24 mpg (US) and 154 g/km (estimated) CO2.

Direct Adaptive Steering

Available on models equipped with the 3.0-liter V6 twin-turbo engine, Infiniti’s second-generation Direct Adaptive Steering has undergone significant re-tuning to enhance steering feel and feedback, while making it possible for the driver to further customize the steering performance according to personal preferences.

Direct Adaptive Steering transmits the driver’s input to the wheels faster than a mechanical system while requiring fewer steering corrections and is able to make 1,000 steering adjustments per second. The new system enhances the steering feel by quickly and intelligently communicating to the driver feedback about road surface and chassis behavior. This instills a secure and confident feeling at the wheel and reduces driver fatigue.

Drive Mode Selector

The wide range of steering customization within Direct Adaptive Steering is accessed through the Drive Mode Selector. Located via menus displayed in the center console, Drive Mode Selector allows the steering response to be selected from six available options: ‘Customize’, ‘Standard’, ‘Snow’, ‘Eco’, ‘Sport’, and – new for certain models – ‘Sport+’.

The Standard mode has been tuned to represent the core performance of the Q60 – offering drivers Infiniti’s unique blend of enhanced ride comfort and agile handling as a default setting. Appropriate for the needs of premium coupe drivers, the Customize steering mode also allows for a high degree of fine tuning. Drivers first select one of three core ‘Modes’ (Standard, Sport and Sport+) and then specify their preferred level of ‘Response’ (Default, Dynamic and Dynamic+). For the highest level of assistance and ultimate sports coupe driving experience, the Q60 driver would choose Sport+ mode with Dynamic+ response – making best use of the Direct Adaptive Steering technology.

The Sport mode enhances the response of Direct Adaptive Steering, elevating the steering effort required while reducing the required steering movement from lock to lock. In the new Sport+ mode, steering effort remains the same as Sport mode, but the response of the steering is further increased, with an even quicker steering ratio for precise performance.

Rack Electronic Power Steering

As standard, Q60 models equipped with the new 3.0-liter V6 twin-turbo engine feature Infiniti’s Rack Electronic Power Steering. This all-new system provides a linear and in-control driving experience that can be tuned through the Drive Mode Selector.

When making a steering input or returning the steering wheel following an input, traditional assisted steering systems can create an unnatural feeling through imprecise control of the power assistance, reducing the feeling of linearity. To counter this, Infiniti’s RackElectronic Power Steering precisely increases the steering effort required as the vehicle’s yaw rate changes, before adjusting to provide more assistance when the wheel returns towards on-center.

The four-cylinder turbo-charged Q60 models are equipped with a speed-sensitive hydraulic electronic rack-and-pinion power steering system as standard. This increases assistance at low speeds and reduces assistance for enhanced feel and response at higher speeds.

Two choices of suspension system allow the driver to tailor a dynamic response from the Q60 that best suits a personal driving style. The standard suspension set-up, shared with the Q50 sports sedan, ensures a low level of road noise and minimal intrusion of unwanted vibrations, while allowing for more direct and linear handling responses. Suspension link layouts and bushings have been modified specifically for their application in the Q60, while shock absorbers are relocated for optimized sports coupe ride and handling.

Dynamic Digital Suspension

An all-new electronic suspension system, Dynamic Digital Suspension, comes as standard on the Q60 Sport grades and has been designed to offer best-in-class handling responses and agility, and enhanced ride comfort – thanks to software and hardware upgrades, including a dedicated new set of dampers. Drivers can change the focus of the suspension from a comfort-biased ride to one which offers more dynamic responses, by placing the electronically adjustable shock absorbers in either Sport or Sport+ modes (adjusted via the Drive Mode Selector), providing firmer damping control for more agile handling. While in these modes, the suspension is constantly adjusting to provide ideal performance and a level ride.

Adaptive Shift Control

The Q60’s seven-speed automatic transmission has been engineered with gear ratios spaced to allow for responsive, direct acceleration. Adaptive Shift Control (ASC) uses a lateral acceleration sensor to detect topographical changes in the road, such as hills or corners, and enhances gear selection patterns according to the changing conditions. ASC also allows the transmission to observe driving behaviors and adapt shifts to driver feedback.

In Sport mode, drivers can select a more aggressive shift pattern, holding on to gears longer to tap in to engines’ maximum performance reserves at higher revolutions. In all instances, the automatic transmission shifts smoothly, with less performance-focused modes giving the car a more relaxed gait for everyday conditions.

Intelligent All-Wheel Drive

The Intelligent All-Wheel Drive (AWD) system provides enhanced stability for greater road holding in low-grip conditions, distributing torque 50:50 between front and rear wheels in its default setting. If the car detects that the extra traction isn’t immediately required, the system will revert to 100% rear-wheel drive, redistributing power to each of the four wheels as conditions change or if it detects a momentary loss of traction.
