Nissan GT-R buyers - skill or just boyracer?

Ever since the R35 Nissan GT-R was introduced in 2008, it basically rewrote the history books on how a supercar can be beaten by superb engineering. Nissan turned the supercar industry upside down with the might GT-R that easily show many supercars a clean pair of heels. The car was made so fast and so easy to drive that one often wonder if there is any skill involved in driving it. As prices for used specimens fall when the newer updated models are released the GT-R has become more affordable to a larger crowd.
Of late, there has been hundreds of used GT-R hitting the streets, many bought by young drivers. The next question is about responsibility. There has been numerous fatal accidents involving GT-Rs that are raced on the streets and highways. The car may make the driver feel like god behind the wheel but there are physical limits. the danger comes when the car is driven beyond those limits and the car will likely end up in a wall or an armco barrier.

The limits of the car is extremely high and the onboard computer will do its best to keep the car under control but there is something called physics and no matter what the on-board computer will do to protect the car, for example: going into a tight 90 degree turn at 180km/h will likely spell trouble. The high limits makes giving a false sense of confidence. The car is ridiculously easy to drive fast and this is like giving a big machine gun to a child. The problem doesn't end there because the car is so easy to modify to boost power many of the owners have gone on to up the car's power beyond 600hp.

The worst thing about this is that many of the young guys who buy this car think they are Lewis Hamilton and is the best driver on earth! the car naturally helps stroke the already inflated ego since most of the work is done by the car. A fat ego, a super fast car and perception of one's amazing skill equals trouble!

We have seen many GT-R owners bragging about how good they are or how fast they are at the pub but are they really that good? if you take them out of the GT-R and put them in a 125cc go-kart how will they perform? I believe that more than 90% of them can barely come within 5 seconds of the lap record on an said go kart track.

Low Octane fuel and American cars

During my recent trip to the US I rented a Dodge Charger 3.6 for the fun of it to see if regular American cars made any progress in terms of development. Here are my findings:
- the car's engine is lazy as usual with good torque at low rpm but the fun stops there!
- the suspension is soft as expected and has good cushy ride on the highways
- the transmission (6 speed auto I think), we acceptable but not particularly fast
- fuel consumption, returned about 30 MPG+ (according to the onboard computer)

The strange thing about this car is that knowing full well that in the west coast of the United States you can easily get RON87 fuel which is super low grade by developed country standards. The car's engine started knocking at 4,500rpm using RON87. I would think that Dodge would design the engine to run efficiently on RON87 since it is a common fuel in US.

I had the chance to dyno test the car to see how much power it would produce at the wheels, to my surprise the 3.6 litre engine only managed 191hp at the wheels which is very low. I would imagine that the transmission would have sapped out about 25% but 191 hp is very low.

The car felt clumsy to drive around the city but was comfortable on the highway. I am not sure how much worst it was before this but in terms of car development the average American car is nowhere near the Europeans or the Japanese!
