Infiniti G37, 2009
Powered by a potent 3.7-litre version of VQ family of petrol engines, the Infiniti G37 has been created to provide pure driving pleasure. There's a choice of rear- or all-wheel drive models with drive taken to the wheels via a slick six-speed manual or an advanced seven-speed automatic transmission.
The Infiniti G37's suspension - double wishbones at the front and a multi-link rear - deliver the perfect blend of sporting handling and superb ride comfort while the longer-than-class-average wheelbase results in a roomy cabin with a specific attention to rear knee room.
Engine and powertrain
At the heart of a sports sedan there needs to be a sporting engine� and this is another area where Infiniti G37 delivers on its promise. It is powered by a new 3.7-litre version of VQ engine family. Regularly honoured in independent awards the world over, the twin cam 24 valve V6 produces over 310PS and an impressive over 350Nm of torque.
Among its many features, the lightweight aluminium engine features a bed-plate construction. A technique that has been used in motor racing for many years, the resulting two-part construction of the cylinder block is more rigid than a single piece casting. Among engine specialists, this configuration signifies a high-performance sporting engine which is uncompromisingly designed for the highest strength and reliability.
Other benefits include reduced vibration levels and higher engine speeds to be reached consistently without damage.
The VQ37 unit also features V-VEL (Variable Valve Event and Lift) technology to optimise efficiency and, in turn, the balance between power, response, fuel efficiency and emissions.
V-VEL continually alters valve lift and therefore the quantity of air in the combustion chamber. At partial throttle - in stop-go city traffic, for example - it will make a small lift thus achieving a more precise fuel/air mix with lower quantities of both to improve fuel consumption. At full throttle, the valve lift is greater, inducting a larger quantity of air into the combustion chamber.
Interior environment
The Infiniti G37's interior is an environment designed to appeal to driver and passengers alike. Quality materials provide the warmth and comfort expected in a premium car, yet the driver's quarters have a 'scooped-out' design to emphasise the concept of a cockpit in direct contrast to the open, spacious design of the passenger area.
The dashboard and centre console adopts Infiniti design DNA with a 'double wave' upper section linked to a central vertical spine for a feeling of solidity. With roots in Japanese design, 'Washi-style' aluminium accents can be found through the cabin. Washi is a form of elegant Japanese handmade paper and textured aluminium trim inserts can be found on the centre console, the instrument binnacle and the door panels. Automatic versions have the option of African rosewood inserts.
Safety
A full complement of six airbags can be found as standard in Infiniti G37. The front seats incorporate hip and thorax bags, while there are front-to-rear curtain airbags for protection in a side impact.
As well as offering occupants the highest level of crash protection, Infiniti has developed a pop-up bonnet to offer greater protection for pedestrians: it is a standard fitting on Infiniti G37.
In the event of a collision, a small pyrotechnic charge raises the trailing edge of the bonnet close to the lower edge of the windscreen. This creates a larger buffer between the bonnet and the 'hard points' of the top of the engine, providing a more yielding surface and helping to reduce potential injuries.
