turbo is the fastest most refined yet! (remember being refined is not necessarily a good thing for a supercar).With a top speed of 189 mph and a 0-62 time of
4.2 seconds this is one seriously fast machine, the 3.6 liter engine pumps out a Ferrari 360 Modena beating 415hp, this is produced with the help of two KKK K64 turbochargers- one to each bank of cylinders.
Each turbocharger compress's 12.3 pounds of air per square inch, (ooh yea by the way the he engine produces a reasonable 115 hp per liter)- I said reasonable because considering that it is turbocharged 115 hp per liter
is not that huge, (the twin turbocharged 2.9 liter Ferrari F40 has a power output of 162 hp per liter)
The six cylinder 180° (boxer, flat) engine is derived from the dry-sump 911 GT3/GT1 engine except this
one is of course turbocharged. It shares the block, the pistons, head castings, smaller valves, a different combustion-chamber shape and the camshaft's chain drive.
O.K. so how much faster is it than the
old shape turbo I hear you ask well here are the numbers- new before old : 0-62 times- 4.2 versus 4.5 seconds, top speed- 189 mph versus 180 mph, and finally horsepower- 415 versus 400 hp. These figures prove that the
new turbo is a fair bit faster than the tubo it replaces (unless you have a tuned version of the older model that is i.e. Ruf, Gamballa etc...).
However, what is debatable is which looks nicer personally I
think that the last 911 Turbo was and still is the best looking one Porsche has ever made- and I am certainly not the only person who thinks so.
Here are the rest of the specs:
0-100 mph in 9.2 sec- (Ferrari F50 does 62 in 3.9 seconds and 0- 100 in 6.0 seconds)
3.6-liter water-cooled 24-valve 180° rear mounted (boxer) engine, pumping out 415 hp@6000 rpm
413 lb-ft of torque from 2700-4600 rpm
9.4:1 compression ratio
Revised six speed manual gearbox
13-inch, cross-drilled, vented disc brakes, with four-piston calipers on each
brake. There will soon the option of ceramic composite brakes (A first for any production car), weighing 50 percent less than standard discs!
18% better fuel economy than previous turbo 911
All wheel drive
A curb weight of 3400 lb
Electronic stability control system
