The changes were revealed to PistonHeads yesterday by GT-R project chief Kazutoshi Mizuno, who was our host yesterday at the company's Nurburgring technical centre where elements of the 2010 upgrade package - and European Spec-V models - are undergoing their final evaluation.
According to Mizuno-san, the suspension tweaks are minor but include marginally stiffer front spring and damper rates, and stiffer bushing for the rear torsion control arms. The aim is to further increase the driver appeal - or to paraphrase the enigmatic chief engineer 'to make the driver's buttocks feel even closer to the rear wheels during sporty driving'.
The adoption of the Spec-V rear diffuser and new NACA ducts next to the rear wheels are there to improve airflow and brake cooling, says Mizuno. The 2010 cars have also been tweaked to meet Euro 5 emissions regs, and an ECU modification improves low-speed tractability in low temperatures when the transmission fluid is still cold.
Spec-M model that has been rumoured for some time. Contrary to the suggestion in our story yesterday, it won't be at the Tokyo motor show next month, but will emerge sometime next year instead.
We shouldn't get too distracted by the 'comfort' tag, they say, as the core package will be largely undiluted. Instead, think of a GT-R 'plus' with extra luxury fittings like a high-end sound system, expensive interior fittings and a more 'bespoke' feel.
Like the Spec-V, the idea of the Spec-M is to increase exclusivity, not improve accessibility, so although the suspension may be set up for a little more comfort we're not expecting the driving experience to feel very different from the standard car.
Meanwhile the 2010 model year GT-R should be available in the UK early next year, around the same time as the Spec-V edition.
