Infiniti has unveiled the hybrid version of its BMW 5-series challenging M saloon at the Paris motor show.
The M35h is the brand’s first hybrid production car and its powertrain won't be used in any other car until the next generation FX is launched.
The M35h uses a conventional automatic gearbox, albeit one with a clutch rather than torque converter, but is spared the CVT whine normally associated with hybrid drive.
It is possible to pull away on electric power alone, and in theory the M35h can be driven on its electric motor up to speeds of 60mph.
The lithium-ion batteries have a 1.3Kw capacity, but the 3.5-litre V6 petrol engine will cut in at around 20 per cent throttle.
Although Infiniti are yet to release official performance and consumption figures, it has confirmed that the M35h will outperform the petrol for acceleration and the diesel for fuel consumption.
