Ten Second Review

The Infiniti M35h hybrid incorporates some intriguing technology and represents a tempting option for city dwelling executives, but it doesn't offer enough to tempt the vast majority of us from our diesel cars. It's well equipped and decently finished but space inside is a little disappointing. Interesting, different and worthy enough, the M35h is clearly targeted across the pond.


Background

Despite its name, the Infiniti marque hasn't been around for too long in the UK and it has yet to significantly dent the consciousness of executive class buyers. Happy with their BMW 5 Series, Audi A6, Jaguar XF or Mercedes E Class models, this group of customers has, to date, been targeted by only one hybrid model, the slow selling Lexus GS450h. The modest take up of hybrids has, to a large extent, been attributed to the sheer excellence of the diesel cars in this class and if the Infiniti M35h hybrid is to elbow some of these vehicles aside, it needs to be very special indeed.
Unlike Lexus, which seems either unable or unwilling to develop a good executive class diesel engine, Infiniti has one on its books already in the shape of the 236bhp 3.0-litre diesel in the M30d variant, so the hybrid model feels as if it has been developed from choice rather than necessity. In order to make any headway, it first needs to establish a case for itself over its oil-burning sibling.


Driving Experience

We've come to expect some sort of technological headliner from most Japanese hybrid cars and the Infiniti M35h is no different. Its most fascinating feature is the Approaching Vehicle Sound for Pedestrians (VSP) which utilises a range of distinctive sounds to help ensure the safety of other road users. VSP is computer controlled and links an in-car sound synthesiser with a speaker built in to the front bumper. It automatically works from start-up to 20mph, cutting back in at 17mph as the vehicle slows. It sounds somewhat like a quieter version of a jet taxiing and gets your attention without sounding harsh or intrusive.
Aside from that, the M35h gets a very punchy 303bhp 3.5-litre petrol V6 augmented by a 67bhp electric motor, the M35h which means a very puncy 5.6 second sprint to 60mph. The transmission is an automatic with internal clutch pack and means that there's not the CVT gearbox whine that often accompanies hybrid cars. The extra 120kg of weight added by the hybrid system means that you shouldn't expect the M35h to feel as wieldy through corners as a conventional petrol-powered M37. It's possible to drive at up to 60mph on electric power alone, but you'll need to have the tactile finesse of a bomb disposal expert with the throttle. Give it any more than about a quarter of the pedal's travel and the petrol engine thrums smoothly into life.


Design and Build

The design of the Infiniti M35h appears to draw upon a number of influences. There's something rather Maserati GranTurismo about the front wheel arches and undeniably overtones of Jaguar XF around the front grille and headlamps. The rear end is less distinguished, tapering to a rather generic blend of Japanese and American design cues. The net result is a car that doesn't quite hang together a cohesive package, lacking the dynamic tension of a modern European design. That said, it is quite distinctive.
Things get better when you drop inside the cabin. Materials quality is extremely good and the fascia design mirrors the organic sweep of the exterior lines but to better effect. There's standard leather trim with a mix of aluminium and piano black detailing. The Infiniti trademark analogue clock sits in the centre of the dash while a large display screen marshals the various ancillary functions. In terms of fit and finish, the M35h isn't quite on a par with Audi but easily stands comparison with BMW and Mercedes. Space in the front is good, despite the broad centre console, but headroom is a little pinched in the rear. The 450-litre boot is also a fair bit smaller than the 520 and 540 litres of space that you get in the BMW 5-series and Mercedes E-class respectively. Moreover, the rear seat doesn't split or fold which also limits versatility.


Market and Model

For the driver, there's an abundance of toys to play with. The list includes climate controlled seats, bi-Xenon adaptive headlights and a range of Bose stereo options. The upmarket sound system has Active Noise Control which detects unwanted low frequency noise in the cabin and plays sound waves of the opposite phase to cancel them out. There's also a Forest Air climate control system which gives an extremely high level of control over temperature, humidity and pollution levels.
Safety equipment provision is equally comprehensive. As well as the full complement of crumple zones and airbags, there's a raft of electronic aids including Intelligent Cruise Control and a Forward Collision Warning system.


Summary

The Infiniti M35h hybrid is an impressive foray into a market that has yet to bloom in this country. Executive class buyers remain firmly wedded to their diesel cars and although the Japanese company has clearly thrown a lot of resources at this model and pioneered some intriguing technical innovations, it's not a car that makes an overwhelmingly convincing case on the balance sheet.
What you do get is a very well finished car that makes light work of city driving and offers an alternative to the 'too cool for school' understatement of the German marques. Ultimately this car feels exactly what it is - a car targeted at the American market that will garner only very minority interest in the UK. Still, as an example of what Infiniti is capable of, it bodes extremely well for when they design some more Eurocentric products.
