Re: McLaren on a winning streak
Herbaliser:Whoopsy:Herbaliser:On country roads the 812 would never give you enough confidence with it's traction issues. It won't break, steer, change direction as precisely as a proper mid-engine supercar. That's what I mean by performance. After the 488 the Autobahn acceleration is a closed chapter for me. I finally reached the level where "it's enough". I am not so crazy to chase other 700hp car.
The comfort levels of the 488 or the 720S are amazing. So why chose the 812 unless you have other priorities? Better investment, engine sound, softer ride... All that has nothing to do with performance.
For most customers and drivers, they WILL go faster on country roads in a 812 than a 720S no matter how much aster a 720S will be.
A 812 is a classic front engine rear drive car, the handling characteristics is the simplest to master, even if it has traction issues and the rear steps out, it will be extremely easy to catch.
720S, or any other mid engine cars for that matters, will catch a lot of drivers by surprise. The inherit willingness to rotate means they are much harder to push, and if they step out it will catch a lot of people out. Most will actually crashed out before finishing the road.
911s, modern ones that had the tail tamed, are also extremely forgiving and easy to drive fast. and the tail rotate so slowly that even if it steps out, there are plenty of time to catch it back.
The interior of the 720S is just super nice, McLaren finally have a nice interior to be proud of. That's space age compared with the old looking 812 interior that's for sure.
That's a rather unconventional theory. The mid engine layout is the most balanced and neutral one, with the least rotational forces, as both the front and the rear are lighter. It has the most predictable behavior because there's no surprising build up of inertia in the front or the rear. The car pivots around the driver which is the most natural thing.
The mid engine layout is the best in every regard except space utilization. The 911 has a rather flowed architecture but it is a testemony of Porsche's engineering brilliance in the way they overcompensate it. We could only dream what would it be if they build a proper lightweight mid engine supercar.
I think what Nick is referring to is that midengined cars have their mass closer to the center so it has a lower polar moment of inertia, like a dumbell with the weights in the center instead of the two ends will spin easier, this will give the car a more agile nimbler turn in and direction changes but also allows the car to spin easier or quicker, less progressive, which can catch people by surprise when going at the limit and may cause less experienced drivers to keep a bigger buffer at the limit as opposed to the front engine RWD. I guess it's analogous to the GT3 vs C4S scenario were the GT3 is the faster car with the best setup for fast driving but a lot of drivers would be faster with the less sporty AWD setup of the C4S on a mountain road.
