 Infiniti Q50, 2014

A New Dimension in Dynamic Design
While Infiniti sports sedans have always been noted for their outstanding proportions and presence, the new Infiniti Q50 adds a new dimension of premium style.

Its strong first impression is anchored by the smooth yet dynamic character line arising from its "double arch" grille. It energetically flows through the bodyside like a wave and merges with the rear end, creating a highly fluid and intriguing profile and fully illustrating the Infiniti Q50's dynamic and athletic stance.

Signature Infiniti exterior design features include the "double arch" grille, dynamic arch roofline and Crescent-cut C-pillar. The front end is decidedly aggressive, with a sport front fascia offered on the Q50 sport models. The new grille's three-dimensional, textural quality is provided by elaborate detailing of the waved mesh pattern surface and chrome surround, while the distinctive LED headlights and marker lights' sharp lines suggest an almost human look.

The lean, robust body sides are designed to anchor the performance stance with a strong, solid "bone" and arched roofline that flows to the Crescent C-pillars that are similar to those that originally appeared on the Essence Concept. In the rear, the side character lines smoothly merge with the shape of the rear LED combination lights. The familiar rear double-arch trunk line completes the strong, unforgettable view from behind. Heated outside mirrors with integrated LED turn signals are standard, while a power sliding and tilting glass sunroof is optionally available.

Other exterior refinements include new door architecture with narrower, roll-formed A- and B-pillar sashes that provide improved ingress and egress, as well as a more open cabin environment. A new color palette has been specially selected to accent the Q50 contours and sculpted surfaces and includes a range of eight premium colors.

The new body design also offers enhanced airflow over both the upper and lower body portions, resulting in a coefficient of drag of just 0.26. The Infiniti Q50 also features zero front and rear lift.

Performance With a Personal Touch
Throughout the Infiniti Q50's development, compromise was never an option. No compromise on innovation, design or performance targets, allowing the development teams to stretch the boundaries of what a sports sedan can be.

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 (est.) and 269 lb-ft of torque (est.) 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 (est.) and 255 lb-ft of torque (est.), while the advanced 50 kW electric motor is rated at 67 horsepower (est.) and 199 lb-ft of torque (est.). The hybrid system net power is 354 horsepower (est.), providing strong acceleration and lean fuel economy.

Both Infiniti 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 Infiniti 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-and-pinion 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.
