Infiniti G Saloon (2009–2013)
The G Saloon went on sale in the UK as Infiniti launched into the market. It's available in the UK in five well equipped versions. Whether ‘entry' model, luxury GT, all-wheel drive x, or sporting S with 4-wheel active steer, all the G37 Saloons are powered by the 3.7-litre V6 petrol engine, compliant with forthcoming Euro 5 emissions standards, mated to a six-speed manual transmission (with optional seven-speed automatic transmission with magnesium gearshift paddles).
High performance comes with 0-62mph taking just 5.8 seconds and a top speed limited to 155mph. Fuel economy on the combined cycle is 26.7mpg with CO2 emissions of 248g/km. The seven-speed automatic betters this with 26.9mpg and 246g/km, while the auto's acceleration to 62mph is only marginally slower at 5.9 seconds - still fast enough to beat many sports cars.
The all-wheel drive models are badged with an ‘x' and use the sophisticated all-electronic torque split system from the EX and FX crossovers. Power distribution is constantly adjusted from 50:50 to 100 per cent to the rear - so that maximum traction is always available on slippery surfaces, but crucially without compromising the G37's rear-drive handling feel. The seven-speed automatic transmission is standard. The G37x accelerates to 62mph in 6.0 seconds and goes on to a top speed of 149mph. Fuel consumption on the combined cycle is 25.7mpg while CO2 emissions are rated at 255 g/km.
The S is the sportiest G37 Saloon and proves it not just with sports seats and aluminium pedals but with engineering changes designed to bring out the maximum potential of the super-stiff G37 chassis and its sophisticated suspension. Chief change is the addition of 4-Wheel Active Steer. This varies the front steering ratio and adjusts the geometry of the rear suspension according to steering input and vehicle speed. With the limited slip diff, four-piston front brakes and recalibrated suspension, handling is taken to a new and higher level.
As well as its sophisticated styling and dynamic driving characteristics, the Saloon offers class-leading room for four/five adults. Equipment is good. Infiniti particularly prides itself on the G37's safety credentials which include standard cornering xenon headlights and a bonnet that pops up in an impact with a pedestrian, providing a potentially life-saving ‘cushion'.
The G Saloon was enhanced for 2010 witha more dynamic look and revised interior, with state-of-the-art infotainment technology available. The changes are subtle but effective - as one glance at the sharper new front-end styling reveals. More sculptural, more distinctive and more indicative of the 320bhp under the bonnet of every G37, the new look moves the Saloon visually closer to its sportier two-door cousin, the G37 Coupe.
New front light clusters - still with xenon adaptive cornering headlights as standard - and a fresh-looking iteration of the familiar double-arch Infiniti grille are the main component changes, proving the rightness of the original design. A redesigned under-bumper section with recessed, wide-set foglights (previously the fogs were set into the main light clusters) gives the 2010 G37 Saloon a more purposeful edge to its already striking visual impact. The rest of the G37 Saloon's body is untouched.
Changes in the cabin are just as subtle but equally tailored to meeting owners' expectations. For instance, the Rosewood interior accents are now high gloss, the leather hues slightly lighter and there's the option of a new Wheat leather colour combined with a black dashboard and upper door trims. Reinforcing the G37's impression of quality is a new aluminium trim design, reminiscent of Japanese calligraphy, along with a redesigned centre console based on that in the EX and FX crossovers. Improving both legibility and design cohesiveness, the gauges and LCD instrument display now use white as background colour. For the first time, Infiniti's much-praised information and entertainment platform, Connectiviti, is available in the Saloon following on from its G37 debut in the Convertible earlier in the year.
The HDD (hard disk drive) based system connects all manner of modern technology, from MP3 players to mobile phones, with seamless efficiency. Connectiviti+ takes things a stage further with a 30GB Music Box and innovative satellite navigation system which, among its long list of functions, can even access built-in Michelin's Red and Green Guides to take you to the door of a top restaurant or hotel.
Three new exterior colours are available for 2010 models: Smokey Quartz, Graphite Shadow and Vibrant Red. All are Scratch-shield paint, of course. Other features unique to the G37 Saloon are its charismatic V6 with VVEL valve technology and its chassis options of rear-wheel drive, four-wheel drive and four-wheel steer for the most sporting S version.
Combining dynamic performance with the safety of intelligent all-wheel drive, the G37x S is the latest addition to the Infiniti G Saloon line-up in the UK. It is the first time Infiniti's sportiest S grade has been available with AWD in the G range. Previously only the GT was available with AWD.
Like all G models, the G37x S is powered by a 316bhp (320PS) 3.7-litre V6 mated to a 7-speed automatic transmission with paddle shifts - a combination that delivers 0-62mph acceleration in just 6.0 seconds. And with Infiniti's torque-sensing AWD system aboard, the swift pace is available virtually irrespective of weather or road surface. The car has a top speed of 149mph and an official combined fuel consumption of 25.7mpg (11.0 l/100km) with emissions of 255g/km.
The newest G model costs from £38,979 and bears all the style, features and technology that set the Infiniti brand apart. The sole AWD model in the G line-up for 2012, the G37x S is distinguished by S hallmarks such as red S badges, 18-inch Sport design alloy wheels and smoked lens headlights. Inside, features include sports seats, with 14-way electric adjustment for the driver, and aluminium pedals and footrest. The G37x S also comes with the Multimedia pack of hard disk drive (HDD) navigation and music systems, 10-speaker Bose ® Premium Sound System, reversing camera and high resolution touch screen.
Like every G model sold in the UK, leather seat facings, Shodo aluminium trim, adaptive bi-Xenon lights, Scratch Shield paint, i-Key smart access, electrically adjustable front seats and steering column, and heated front seats are standard. The only option for any G model is metallic paint (£577).
The G37x S takes its place in a new-look G line-up. The flagship G37 S Premium (£40,619) builds its credentials with keen drivers thanks to 4-Wheel Active Steer (4WAS), sports suspension, sports brakes and Viscous Limited Slip Differential to get the most from the balanced rear-drive chassis. It also comes with Intelligent Cruise Control (ICC) and Intelligent Brake Assist (IBA) among a suite of electronic safety aids.
Two GT models, both now in rear-wheel drive form only, make up the entry point to the range. The G37 GT costs from £34,909 while the GT Premium - with Multimedia pack and sunroof among its extras features - costs from £37,849 OTR.
The G family in the UK is completed for 2012 by the G37 Coupé (from £36,359) and G37 Convertible (from £45,235), both of which continue unchanged.
