New engine, chassis technologies deliver empowering performance
The new 2016 Infiniti Q50 sports saloon will soon be launched with a number of performance and dynamic upgrades that deliver a more empowering and rewarding drive experience. The comprehensive updates include next-generation ride and handling technologies and all-new advanced turbocharged V6 powertrains.
Making its debut on an Infiniti is the company’s second-generation Direct Adaptive Steering, comprehensively modified from the ground-breaking first-generation system. The standard steering mode now offers advanced levels of steering feel and feedback – more akin to that of a conventional steering system.
The new Q50 also features Infiniti’s Dynamic Digital Suspension (DDS) for the first time, which gives the sports saloon an optimal blend of ride comfort and class-leading response and agility. For those drivers looking for a blend of dynamic settings tailored to their own particular requirements and tastes, the Q50’s Drive Mode Selector (DMS) can be augmented with a “Personal” mode, that permits a bespoke mix of engine, suspension and steering characteristics.
Five powertrain options are offered with the Infiniti Q50, and for the 2016 model these include an advanced, all-new 3.0-liter V6 twin-turbo gasoline engine with direct injection.
Dynamic performance from innovative technology
A range of new and innovative ride and handling technologies deliver on the promise of the Q50’s daring design and install confidence in all driving conditions.
Infiniti Q50 models equipped with the new 3.0-liter V6 twin-turbo engine, or the hybrid powertrain, come available with the second-generation Infiniti Direct Adaptive Steering (DAS), which has undergone significant re-tuning to greatly enhance steering feel and feedback.
The changes to DAS – the world’s first digital steering system – have been made following extensive consultation with existing Q50 customers around the world and over 625,000 miles of testing.
For the new second generation DAS, engineers have optimized the control logic to improve feedback from the road. They have fine-tuned parameters so that the default setting better mimics the feeling drivers are used to from conventional systems.
The new system also provides more customization options, giving drivers’ flexibility to choose the level of steering assistance and feedback according to personal preferences.
The new version of DAS works with Active Lane Control to maintain lane positioning against crosswinds and uneven road surfaces. This semi-autonomous capability is a precursor to future steering systems that will form a key building block on the way to achieving fully-autonomous driving.
As standard, Q50 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.
The Q50 features a multi-link suspension and, for the 2016 model, revised suspension settings provide an improved balance between confident handling and a comfortable ride. The front suspension is a double-wishbone design, while the revised rear suspension utilizes a multi-link design with coil springs and Dual Flow Path shock absorbers.
The Q50 now benefits from revised front and rear stabilizer bars. The result is heightening resistance to unwanted adjustments in the lateral movement of the suspension, affording a flatter ride and greater agility during cornering.
The 2016 Q50 Sport models with 3.0-liter twin turbo powertrains are upgraded with DDS for the first time, which offers enhanced ride comfort with class-leading response and agility.
In all modes, DDS also constantly adjusts the shock absorber valve within a wide range of damping force to control body motion when cornering. It monitors body roll, pitch and bounce rate to restrain body motion for a comfortable, confident and insulated ride in all conditions, ensuring that bumps and undulating road conditions are absorbed to maintain flat body pressure.
Infiniti’s most advanced V6 leads the refreshed engine line-up
The all-new 3.0-liter V6 twin-turbo engine from the new and exclusive VR powertrain family has been developed to deliver optimal power and torque, alongside greater fuel efficiency. The high-output version of the power unit delivers 400 horsepower (298 kilowatts) at 6,400 revolutions per minute and 475 Newton-meters (350 pound-feet) maximum torque at 1,600-5,200 rpm; while the 300 hp (224 kW) version (at 6,400 rpm) produces 400 Nm (295 lb-ft) torque at 1,600-5,200 rpm.
These outputs have been achieved while ensuring an improvement in fuel efficiency of up to 6.7 percent, representing a best-in-class power-to-efficiency ratio for the 400-hp power unit.
A new high-pressure direct injection gasoline (DIG) system, introduced for the first time, allows for precise control of fuel injection into the combustion chamber depending on throttle position and current engine speed.
The Q50’s advanced hybrid powertrain combines a 3.5-liter 24-valve DOHC aluminum-alloy V6 and a compact laminated lithium-ion battery with an innovative one-motor, two-clutch control. The system’s V6 is rated at 302 hp and 350 Nm of torque, while the advanced 50 kW electric motor is rated at 67 hp and 270 Nm of torque. The hybrid system’s net power is 360 hp.
The hybrid powertrain is designed to put performance first, while bringing significant benefits for 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 an energetic feel under all driving conditions.
Smooth shifts from seven-speed automatic transmission
All Q50 powertrains are matched to an advanced seven-speed electronically controlled automatic transmission with manual shift mode and steering column-mounted magnesium paddle shifters.
Adaptive Shift Control enhances gear selection by using a lateral acceleration sensor to detect changes in the road, such as hills and turns. Sport mode allows the driver to select a more aggressive shift pattern with automatic up- and down-shifting at higher engine speeds. The combined effect is for any driver to enjoy quick, smooth shifts and gear choices that are appropriate to both the road and the desired driving style.
