2015 INFINITI Q70 Hybrid Press Kit: Overview
The INFINITI Q70 Hybrid continues to stand out as a true luxury performance “driver’s” hybrid. For 2015, the Q70 Hybrid shares the wide range of enhancements given to the standard 2015 INFINITI Q70 – starting with updated exterior styling and the addition of several of INFINITI’s pioneer technologies, such as Predictive Forward Collision Warning (PFCW) and Backup Collision Intervention (BCI).
The Q70 Hybrid’s revised exterior includes new front and rear fascias, new grille design, INFINITI signature LED headlights, LED taillights, LED fog lights and side rearview mirrors with integrated LED turn signals. Three new exterior colors have also been added for 2015: Hermosa Blue, Chestnut Bronze and Graphite Shadow. A special premium Pearl finish is also available with the Moonlight White exterior.
The 2015 INFINITI Q70 Hybrid also includes revised interior content and trim, with leatherette replacing leather-appointed seating (leather-appointed seating is available with the Premium Package). Other changes include revised 18-inch aluminum-alloy wheel designs and the availability of Around View® Monitor with Moving Object Detection (MOD) and Forward Emergency Braking (FEB).
What is unchanged for the new model year is the INFINITI Q70 Hybrid’s unprecedented balance of three attributes:
- Power – the innovative one-motor, two-clutch parallel hybrid system in the INFINITI Q70 Hybrid delivers thrilling performance and is capable of driving in pure electric mode at speeds up to 62 mph
- Luxury – maintaining the INFINITI Q70 Sedan’s engaging driving feel and extensive array of standard comfort and convenience features
- Efficiency – utilizing the INFINITI Direct Response Hybrid® system, with a powerful yet compact Lithium-ion battery pack, advanced 3.5-liter V6 engine, 50kW electric motor, connected to an electronic 7-speed automatic transmission, helps achieve fuel economy of 34 miles per gallon Highway, 29 mpg City and 31 mpg combined
The Q70 Hybrid’s inspired – and green – performance is based on an innovative yet elegantly simple gasoline/electric drivetrain, which ensures that zero-emissions electric propulsion is used more often, for longer periods and at higher speeds than in typical hybrids. The Q70 Hybrid can drive on electric power alone at speeds up to 62 mph and can travel on electric propulsion for up to 1.2 miles at a time. INFINITI’s internal testing has shown that in mixed diving, the vehicle is able to drive in electric only mode for as much as 50% of the time.
INFINITI Direct Response Hybrid® System
At the heart of the Q70 Hybrid is a front-engine, rear-wheel drive layout based around an innovative INFINITI Direct Response Hybrid® one-motor, two-clutch parallel hybrid system. The electric motor is rated at 50 kW (67 hp) and peak torque of 214 lb-ft (an increase from the previous year’s 199 lb-ft). It acts as either a propulsion unit, alone or in tandem with the V6, or as a power generator.
As well as charging the battery in the normal way, the motor recovers energy otherwise lost during deceleration and braking.
The first of the two clutches is a dry clutch installed between the V6 engine and the electric motor. It facilitates full decoupling of the V6 when the car is in electric drive and power regeneration modes. Decoupling the V6 reduces mechanical losses and boosts efficiency of the electric motor. The proven 302-horsepower 3.5-liter DOHC 24-valve V6 was chosen for torque characteristics (258 lb-ft at 5,000 rpm) that perfectly complement the electric motor’s output. It combines with the electric motor and high-power battery to produce 360 horsepower (hybrid system net power).
Both the gasoline V6 and electric motor deliver their power to the rear wheels via a 7-speed automatic transmission. The electric motor’s high torque from zero rpm provides strong performance from a standing start and contributes to the sporting feel.
The Q70 Hybrid’s Lithium-ion battery pack is designed to quickly alternate between charging/discharging and, size for size, offers twice as powerful as conventional Nickel-Metal Hydride batteries. Along with its fast charge/discharge response and 1.4 kWh capacity, the Lithium-ion battery pack is laminated to enhance the cooling performance. Temperature stability is further improved by the use of manganese positive electrodes, helping provide exceptional battery reliability.
The batteries are located behind the rear seat, but the Q70 Hybrid is one hybrid sedan with practical luggage room, with the trunk able to accommodate four golf bags or two large suitcases.
Extra weight, the bane of many hybrids, is kept in check in the Q70 Hybrid by the lightweight batteries and features such as the single electric motor, no torque converter and innovative steering and braking systems. The weight gain over the non-hybrid Q70 has been kept down to less than 275 pounds.
Innovative Steering and Braking Systems
The INFINITI Q70 Hybrid is equipped with innovative steering and braking technologies, which have been designed to deliver both environmental benefits and natural driving feel. The Hybrid Electric Power Steering is an electro-hydraulic system with “on-demand” assistance. It offers the advantages of both types of steering – the natural and smooth feel of hydraulic power steering and the improved fuel efficiency of an electric system. The assist motor cuts in only when the wheel is turned, further boosting efficiency. The system is more compact and lighter than traditional power steering set-ups, achieved by integrating multiple parts. In addition, the Hybrid Electric Power Steering system helps reduce fuel consumption by approximately two percent.
The Electric Driven Intelligent Brake system is similarly designed primarily to suit sport sedan buyers’ needs, while at the same time contributing to the Q70 Hybrid’s efficient operation.
An electric booster motor is utilized to operate the brake cylinders, saving mass that would otherwise be added by a reserve pressure tank. The primary benefit of the system is that by controlling both regenerative and friction braking, depending on motor operation and battery condition, the INFINITI Q70 Hybrid operates more efficiently – recovering otherwise wasted energy. The simplicity of these elegant mechanical solutions, with their emphasis on compactness, lightweight and fewer parts, is made possible by advanced computerized control.
The Q70 Hybrid utilizes the proven FM (Front Mid-ship) platform, along with the Q70’s independent double-wishbone design in front and multi-link independent system in the rear. The suspension system also features front and rear stabilizer bars and double-piston shock absorbers that have been specially tuned for use with the Q70 Hybrid.
Newly designed 18-inch aluminum-alloy wheels and 245/50R18 all-season performance tires are standard.
The INFINITI Q70 Hybrid also offers a standard feature to help alert pedestrians to its presence. The Approaching Vehicle Sound for Pedestrians (VSP) system uses a range of distinctive sounds to help alert pedestrians that the vehicle is approaching. VSP automatically works from start-up to approximately 15 miles per hour, cutting back in at approximately 15 miles per hour as the vehicle slows.
Exterior and Interior Design: Pure INFINITI
Like the gasoline engine-equipped INFINITI Q70, the 2015 INFINITI Q70 Hybrid features an elegant yet sporty exterior and interior design. The new dramatic exterior design gives the premium sedan an even more upscale image. The front of the Q70 Hybrid includes new LED headlights, new double-arch grille with high-quality waved mesh finish and chrome surround, new front bumper and integrated LED fog lights. The redesigned rear features new LED combination lights, new trunklid shape and chrome rear finisher.
As in previous years, the balanced, rear-wheel drive proportions and stance, with a long, low hood and high rear deck, provides a roomy cabin, uncompromised by the Q70 Hybrid’s compact battery design (located behind the rear seat).
The deep body shape of the fenders and doors give the Q70 sedan a powerful look unlike anything on the road. The wave-style doors are constructed from aluminum for light weight, despite the material’s difficult formability. Other exterior features include an expressive, signature INFINITI double-arch upright low grille and crystal-look headlight clusters, and a wave-like trunk with a high aerodynamic performance that works like a spoiler to increase downforce.
