2011 Infiniti Coupe Review

The Infiniti G37 Coupé offers dramatic performance in an attractive form of ownership. Although they share most of the material with the Infiniti G37 sedan, the coupe is designed to appeal to different buyers.

The dynamic styling allied to its obvious performance potential will appeal to people who appreciate good design and enjoy beautiful driving. They are not inclined to follow the herd ... and they may not even running a coupe.

"The typical buyer of the Infiniti G37 Coupe is slightly younger than four-door buyer, but no less demanding. He is one who appreciates quality but wants to make a statement even stronger," said Jim Wright, Vice President, Infiniti Europe .

"Infiniti G37 Coupé buyer might be a driver coupe, but it is equally likely to own property or sport compact SUV."

When not in an Infiniti G37 Coupe, it will find the exterior design is matched by a refined interior. And when he starts the engine, he will find a true performance car that delivers what it promises. The maximum speed is limited to 250 km / h (155 mph) for 0-100 km / h takes only 5.8 seconds (on M / T version).

There are three versions of the Infiniti G37 Coupe offers - a well-equipped G37 Coupe, more luxurious GT version with leather interior, and sports-oriented in the S version is equipped with 4-Wheel Active Steer system, viscous limited slip differential (VLSD) and sports suspension among other changes.

 

"Infiniti G37 Coupé takes the best of the four-door and adds even more. This is a car designed to appeal to the emotions, but it offers a practical level, as well," says Bastien Schupp, Marketing Director, Infiniti Europe.

Exterior design

A long hood, short overhangs and dramatically sloping roof line give the Infiniti G37 Coupé a silhouette that sets it apart from competing products based more on their sedan counterparts.

Designed for modern sports car without compromise, the Infiniti G37 Coupé has elegant and sophisticated proportions allied expressive, curved shoulder line gives a sense of movement while seated. A roof line as short and as low also helps to highlight the Coupe and the low center of gravity to give a clear indication that this is essentially a rear-wheel drive vehicles.

The curved lines "character" on the front of the car mimic the lines of the front wings and help give the Coupé a more athletic and aggressive, while the aluminum hood contains a wave-style natural power dome to Clearly the strength of this below.

A special production process has been developed for the installation of the headlights to ensure tight tolerances and build a precise fit into the complex front fascia.

 

Thank you to the shorter body, shoulders at the back Coupé is even more muscular than the sedan, while the integrated rear spoiler is more pronounced. The jewel-like taillights feature LED lamps to reinforce the high-tech appeal of the coupe.

The indoor environment

The Infiniti G37 Coupe offers sporty driving environment for the driver and opening a luxury for the passengers. The dashboard and center console with color display seven-inch adopts Infiniti design DNA with a top section "double wave" linked to a central vertical spine for a solid feel. Aluminum inserts textured finish can be found in the center console, instrument panel and interior door panels.

 

His door trim graceful curve were inspired by traditional Japanese ceremonial swords while the trim cut is inspired by the Japanese washi handmade paper. Other signature Infiniti features are the elegant analogue clock on the dashboard and purple backlighting of instruments and controls.

With its long wheelbase, there is room for two adults in the back of the easy access and exit doors open wide and bending electric front seats and slides. Convenience and load the Infiniti G37 Coupé is further improved by folding the rear seats

Engine and powertrain

Last Infiniti 3.7-liter V6 is a powerful recovery, high, 24-valve twin cam unit producing 235 kW at 7000 rpm (320 hp) and an impressive 360 ​​Nm of torque at 5200 rpm.

Constructed of lightweight aluminum, the engine has a bed in the construction of two plates, which is more rigid than a single piece casting for reduced levels of vibration. It also allows the continued use at higher revs: the V6 is red-lined at 7,500 rpm.

The VQ37 unit features VVEL (Variable Valve Event and Lift) technology to maximize efficiency and, in turn, the balance between power, response, fuel consumption and emissions.

By continually altering valve lift and therefore the amount of air in the combustion chamber, which provides a more powerful combustion phase to increase torque and horsepower. Best of all, such as control valves in consumption rather than a conventional butterfly, response to throttle inputs is immediate. VVEL improves fuel economy and reduces emissions compared to standard systems of valve lift.

Precise mapping of the ECU, meanwhile, helps the engine provide a progressive increase in horsepower and torque, providing a 'building wave' of acceleration rather than a peaky power delivery.

It offers a top speed of 250 km / h (155 mph) and 0-100 km / h (0-62 mph) taking 5.8 seconds (M / T model). Combined fuel economy cycle is 10.5 l/100 km (26.9 mpg), while the CO2 figure is 249 Coupe g / km. The engine is fully compliant with Euro 5 emission requirements.

 

With the performance profile Coupe, Infiniti engineers have developed a special soundtrack music for the car. Equal length tubular exhaust manifolds and a symmetrical exhaust and silencer system have allowed engineers to create a smooth linear sound balance between the notes high and low frequencies.

And good transmission shift six-speed manual, Hyundai Coupe G37 is available with a new seven-speed automatic option with Adaptive Shift Control (ASC) and magnesium paddles mounted behind the wheel.

Chassis and driving dynamics

Infiniti G37 Coupé uses the second-generation version of Infiniti FM platform. The location of the "front midship" engine sees the compact V6 mounted in the front of the car, but as low and as far as possible, with most of the block behind the front axle line. The result of the reduction in the center of gravity and can deliver in front of the optimal weight on the rear.

The fully independent suspension uses lightweight aluminum components to reduce weight as much as possible. A double wishbone front and multi-link arrangement mounted a cradle to the back ally with a highly rigid body, the Infiniti G37 Coupé agile handling perfectly compatible with its performance potential.

All versions of the Infiniti G37 Coupe equipped with the Electronic Stability Program (ESP), while the steering four ventilated disc brakes have a four-channel, four sensor anti-lock braking (ABS), electronic brake force distribution ( EBD) and Brake Assist (BA) by default.

 

To improve the feel of braking, the Infiniti G37 Coupé uses a 'link-design' pedal which becomes progressively firmer as g-forces and increases the speed of the vehicle. As a result, the driver a more direct sense of the forces acting on the car as high-speed brakes, and for the benefit of increased assistance. At lower speeds the brake is easier to use, but with more travel relative to assistance.

The steering system is a vehicle speed sensor type with a double-orifice structure, which provides optimum steering effort at low speeds and high.

G37S Sport oriented version has a number of changes to the chassis, in accordance with its sharp profile. The biggest improvement is the addition of the 4-Wheel Active Steer (4WAS), which helps improve processing performance even more by varying the front steering ratio and adjusting the rear suspension geometry for the input direction and speed of the vehicle.

Other standard features of the G37S include a viscous limited-slip differential, recalibrated suspension settings and an enhanced braking system with four piston brakes in front and two rear piston.

Standard equipment and options

Infiniti G37 Coupe has a wide range of easy to use - and, above all, useful - standard equipment, with options for those who want more of a statement.

Standard features include an intelligent I-Key with smart access and push button starter, six-disc, seven speaker audio system with an RCA AUX jack for MP3 players. Phone Bluetooth connectivity and cruise control with speed limiter can be used through the turns, leather-wrapped multifunction steering wheel.

 

Other standard features include power seats (eight-way adjustable driver's side and four tracks for the passenger), aluminum pedals and footrest, auto-dimming rearview mirror, sensors front and rear parking pilots automatic windshield wiper, fog 18-inch alloys, six airbags and integrated fog lamps. For the perfect driving position, the cab is not installed on the dashboard, but the steering column itself, and moves with the wheel when it adjusts for reach and rake.

Adaptive Front Lighting (AFS) and the painting "Scratch Shield" are also standard. Bi-Xenon headlamps are linked to steering inputs and automatically follow the path of the front wheel to achieve wide distribution of light around corners and on winding roads. "Scratch Shield" paint incorporates a special highly elastic resin within the conventional coatings to increase the flexibility of the paint. A car painted with "Scratch Shield" paint can exhibit up to five times fewer scratches that conventional coatings when exposed to the same conditions.

G37 GT version adds comfort with leather upholstery, driver seat 10-way power lumbar support and memory, and a front passenger seat 8-powered. Heated front seats are standard and the I-key includes memory locations for the driver's seat, steering wheel and mirrors.

In addition to the chassis and dynamic changes, G37S adds sports seats with driver manual stretching. Self-padded with leather seats and a heated and have 14 pieces adjustment (driver) and 8-way power adjustment (passenger). No tire pressure monitoring system standard on both 19-inch light alloy wheels sport bikes.

The biggest opportunity is the new seven-speed automatic with manual mode and magnesium paddle shifters, which allows the driver to the transmission without releasing their hands from the steering wheel. With its additional forward gear, the new automatic transmission wider dissemination of the reports for the benefit of fuel consumption and handling. The seventh speed is effectively an overdrive ratio, returning improved fuel economy on a constant acceleration without compromising flexibility in gear for overtaking. The crossing points are tuned to keep the engine in most of the torque curve, ensuring there is always a healthy reserve when the driver wants to overtake. Adaptive Shift Control link (ASC) system switches between three different programs based on feedback of the major control systems throughout the car.

 

Other options include Intelligent Cruise Control (ICC), which uses brake sensors, gas and laser to help maintain a fixed distance between the Infiniti G37 Coupe and the car ahead. In the automatic transmission, reduces the workload of the driver software provides even more of the ICC to work from 0 km / h to 180 km / h thanks to "Full Speed ​​Range" feature. An integral part of the option ICC for models A / T, the braking system with intelligent analysis of closing speed of a vehicle until help reduce the damage caused by a rear impact. If the driver needs to take action immediately to avoid a collision, the system warns the pilot quickly or can even activate the brakes to slow the vehicle.

A custom designed Bose ® sets a new standard for performance in a car stereo. Its 11 high performance speakers provide crisp musical detail, with notes percussive bass bringing G Coupé owners closer to the power and emotion of a live concert. To achieve this, Bose ® engineers used proprietary digital signal processing and multiple channels of custom equalization to help adjust the sound specifically for the vehicle. Bose ® Sound System is available as part of a multimedia package also includes a DVD navigation system with voice recognition and a rear parking camera. Final options include a sunroof electric glass, metallic paint and a temporary spare wheel (replacing standard tire repair kit), while a subtle African interior trim rosewood is available on the G37 GT.

Security

High levels of passive safety were a priority in the design phase. Consequently, the Infiniti G37 Coupe a complete range of six airbags, with dual air bags front and center, the seat belt sensors and passenger occupancy sensor. The front seats incorporate hip and thorax bags, while there are front and rear curtain airbags for side impact protection.

In addition, the standard is a pop-up bonnet, designed to offer greater crash protection for pedestrians. In a collision, a small pyrotechnic charge to lift the rear edge of the bonnet near the bottom of the windshield. This creates a larger buffer for the hood and top of the engine, which provides most of the surface is obtained, which in turn will help reduce potential injuries.

Quality

Infiniti is synonymous with quality for your vehicle, and is something that does not happen by accident.

 

On the Tochigi production line in Japan every vehicle - not just every tenth - is laser scanned to ensure that panel gaps are within prescribed limits.

The design and development, new models tested, not only the land of Hokkaido Infiniti, but also tries to Tochigi and Motegi test and race complexes in Japan. Infiniti also has a large base of 12340000 square meters of the hot weather testing in Arizona.

Test every Infiniti in the harshest conditions, over thousands and thousands of miles of durability and peace of mind that buyers can expect the products.
