Revised Nissan 350Z Coming
13th February, 2007 | ||||
As well as a world premiere of a unknown new model, Nissan will be showing,
at the 2007 Geneva Motor Show, the updated 350Z which will reinforce its
credentials as a pure sports car with thrilling, involving performance. With the fitment of the next generation 3.5 V6 engine – engine code
VQ35HR – power has risen to 230 kW at 6,800 rpm and torque is now rated at
358 Nm at 4,800 rpm, while the maximum engine speed has increased by 500 rpm
to 7,500 rpm. Nearly 80% of major engine parts are new, providing improved
acceleration and responsiveness. To achieve the additional performance, a dual intake system has been
fitted and the variable valve timing system has a wider range of operation, plus
the addition of a common length exhaust manifold reduces back pressure. Those
changes combine to boost low and mid-range torque. In order to achieve the higher rev limit, the crank journal and crank
pin have increased in size. At the bottom of the engine, a ladder frame has been
added to stiffen the crank and reduce vibration. The introduction of a second knock sensor, an asymmetric piston
pattern, improved cylinder cooling and iridium spark plugs will combine to
improve the efficiency of the ignition cycle, while an increase in compression
ratio from 10.3 to 10.6 has liberated more top end power. Despite all these
changes, weight and fuel consumption remain unchanged, but the engine’s centre
of gravity has been lowered by 15 mm. To accommodate the new engine the front bonnet has been discreetly
redesigned and is now reminiscent of the original 240Z, thanks to a slightly
raised profile, while three new exterior colours will also be offered. Temper
Orange is a striking shade but also contains a subtle green “flip” which can be
seen in soft light and gives the car a surprising tone, while a new grey –
Precision Grey – and Night Blue complete the colour line-up. Inside, a new trim has also been introduced, which is called Frost
Grey. It is a pale tone and adds a touch of sophistication to the car’s
interior. As well as a new interior trim colour, another important change to
the interior is the fitment of Active Headrestraints, to minimise the chances of
neck injury in the event of a rear impact. And to improve on-road refinement, the 350Z is now equipped with
Bridgestone Potenza RE050A tyres, however grip levels remain unaffected. Sales of the newly revised 350Z are expected to begin around the third quarter
of this year. |
