Infiniti FX37: In Detail

 Infiniti FX37: In Detail
2008 Infiniti FX37 in New York / Infiniti

3.7 V6 with plenty of go

A new member of the Infiniti family is going on sale in Europe beginning in October 2008. Downsized to a 3.7-litre V6, the new Infiniti FX37 is an SUV full of sports car soul, a car designed to sit passengers up high while giving the driver a driving experience associated with sporting coupes.

The new 3.7-litre moving the FX37 forth incorporates Variable Valve Event and Lift (VVEL) technology, which continuously changes valve lift and subsequently the amount of air in the combustion chamber. So more power, at the same time lower fuel consumption and fewer bad emissions. Power is a competent 320PS and 360Nm of torque. Its ambitions can therefore not be questioned, at least on paper. From this comes a 7-speed automatic gearbox with paddle shifts to further drive home the “sportiness” line.

Some more good news. Infiniti’s intelligent 4WD system allows for a notable amount of oversteer, therefore letting the car behave as a rear-wheel-driven sports sedan. In fact, at acceleration the system is at full 4WD mode, but once the car gets going and sense 4WD is no longer needed, it sends torque to the rear wheels. Often 100% of it too! The double wishbone setup upfront as well as multi-link choice for the back ensure a confident drive in virtually every condition.

Two distinctive packs are offered for FX37, to satisfy a wider range of customers. After all, Infiniti plans on making the FX37 account for up to 80 percent of the FX range in Europe. The two packs are Sport and Multimedia, where the former offers a system that continuously alters the damping settings for optimal ride and handling. Multimedia kicks a BOSE 11-speaker sound system with sat nav and the cool but optional Around View Monitor which allows for a 360-degree view of the immediate surroundings. We really like!

Infiniti Europe has announced that the dramatic V8-powered Infiniti FX50, revealed at the recent Geneva Motor Show, will be joined at launch by a V6 version with 320PS to be called FX37. The FX37 blends sports car performance with SUV practicality to complete Infiniti’s range of luxury saloon, coupe and crossover models. It will go on sale across Europe together with the G37 Saloon, G37 Coupe, EX37 and FX50 starting from October 2008.

 

 

FX37 in detail

A genuine fusion of sports car and SUV, the FX37’s dramatic styling – shared with the FX50 – sets it apart from the crowd. Built on Infiniti’s FM (front-midships) platform, the FX37 blends sports car proportions with the character of a 4x4. That means a long bonnet and wheelbase, short overhangs and a coupé-like roofline, with the stance and strength of an SUV.
Engine
The Infiniti FX37 is powered by the 3.7-litre V6 petrol engine delivering 320PS at 7,000 rpm and a healthy 360Nm of torque (comparable figures for the V8 FX50 are 390PS and 500Nm).
A member of the multi-award winning VQ engine family, the all-aluminium 24-valve twin cam unit 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.
It is a configuration that signifies a high-performance sporting engine designed for the highest strength and reliability. Other benefits include reduced vibration levels and higher engine speeds to be reached consistently without damage.

The engine, which is fully Euro 5 compliant, incorporates VVEL (Variable Valve Event and Lift) technology to optimise efficiency and, in turn, the balance between power, response, fuel efficiency and emissions. VVEL continually alters valve lift and therefore the quantity of air in the combustion chamber. The result is a more powerful combustion phase increasing torque and power.
Precise mapping of the ECU, meanwhile, helps the engine provide a progressive ‘swell’ of power and torque, providing a ‘building wave’ of acceleration rather than a peaky power delivery.
FX37 comes with a new seven-speed automatic transmission with Adaptive Shift Control (ASC) as standard providing a wider spread of transmission ratios for improved fuel consumption and drivability. The seventh speed is effectively an overdrive ratio, returning improved fuel economy on a steady throttle without compromising in-gear flexibility for overtaking.
Shift points are tuned to keep the engine in the largest part of the torque curve, ensuring there is always a healthy reserve when the driver wants to overtake. The linked ASC system switches between three different programs depending on input from the major control systems throughout the car. Manual shifts can be made via paddle shifts mounted behind the steering wheel.

Chassis

Suspension design is fully independent and uses lightweight aluminium components to reduce weight as much as possible. With a double wishbone set up at the front, a multi-link arrangement mounted on a subframe behind and an extremely rigid bodyshell, FX37 combines agility with exceptional ride comfort.
In keeping with its crossover role, FX37 features Infiniti’s ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split) four-wheel drive technology. The system uses an active torque distribution management system with an active centre clutch for smooth starts, greater grip and better manoeuvrability on slippery surfaces without compromising the vehicle’s rear-wheel drive performance characteristics on dry roads. Torque distribution is anything from 50:50 up to 0:100, front to rear. Unlike permanent 4x4 systems, which can deaden the steering feel and dull the driving dynamics, the electromagnetic torque transfer at the heart of ATTESA E-TS intelligent 4WD’s system permits an element of oversteer for a more sporting drive.

I like Infiniti cars, but their FX's have always looked like something that needs to be flushed.

I think you guys need to see this car in person to really see how beautiful this is. The older one was nice and this one tops it in a big way. Even if you dont like the styling you will fall in love with it as soon as you touch the gas pedal or even sit in it.

I hate the rear ends of these Infini SUVs. Nissan can make them so much better on their Muranos, but they're just plain ugly on the FX. Not that I've ever liked the aesthetic qualities of the FX; yea they're innovative in design but what's the point if they're going to be so ugly?
