Acura NSX aims for Nissan GT-R’s Nurburgring Lap Times
quote:
Despite being delayed over and over again, Japan’s Best Car Magazine provides some extra detail regarding the upcoming NSX.
With the appearance of the Honda S2000 bodied NSX replacement last year at the Nurburgring circuit in Germany, things seemed well underway with NSX development and put many Honda enthusiasts at ease as to whether an NSX replacement would ever eventuate. Well things have steadily gathered pace it seems with Honda ready to test the new NSX’s bodywork strength and aerodynamics starting late this month. The biggest news would have to be Honda’s intention of getting a 7:30.00 lap time around the Nurburgring!
The NSX is rumored to get a front mounted 90 degree V10 with a capacity of 4.5 liters and putting out 122ps/liter for a total of around 550ps and 55.0kg/m torque. Previous reports quoted a 72 degree angle for the cylinder banks, but it seems that a 90 degree angle (like the F1 V10) isn’t too wide as some thought. Moreover the SH-AWD system to be incorporated in the new NSX will be housed with the rear differential and will spread power to the left and right rear wheels, and the front and back wheels (as well as stability control) to give what Best Car describes as “dream cornering speed ability”. Motoharu Kurosawa, a retired racing driver and a frequent test driver for Best Car, was chosen to help Honda engineers develop the SH-AWD system for the new NSX and has had a lot of experience in this regard with other car manufacturers such as Nissan. The aim is to give the FR based AWD system “world class” dynamics an to achieve the seven and a half minute lap time at Nurburgring.
The SH-AWD system will operate with a 30% front, 70% rear power distribution under normal driving, but anywhere up to 70% power can be delivered to the front wheels if needed. Likewise the rear wheels can have anything up to 100% power delivered to either side (eg: 0% right, 100% left) in order to provide the best cornering speed. The reaction time of the SH-AWD system is said to be extremely fast due to its positioning next to the rear differential and the use of a direct electromagnetic clutch arrangement. Best Car point out that a weight of about 1400kg would be needed to achieve a 7:30.00 lap time around the Nurburgring, but this may well be wishful thinking due to the new NSX’s 2+2 seating arrangement and slightly large proportions with (length/width/height) 4610mm x 1950mm x 1250mm dimensions expected to exceed 1500kg.
We will have to wait until late this month or in May to see whether Honda will bring out the new NSX test car again, but one thing is for sure, it won’t be wearing the same body work as seen in January this year…
