Lamborghini announced yesterday the limited-edition Lamborghini LP 670-4 SuperVeloce — the fastest production Lambo ever. Which obviously says a bit. Sant’Agata is only going to produce 350 of these steroid-addled bats (120 for USA) at $450,000 a pop. This latest revelation of the Murcielago improves its 6.5 liter V12’s output by 30 horses to 670 horsepower, boasting a top speed of 212 MPH and a 0-62 mph (0-100 kmh) in 3.2 secs — making the SuperVeloce top in its class both in horsepower and acceleration.

Although this boost in hps is significant, the performance improvement is due more to its shedding 220 lbs (100 kgs)  of pork. With the exception of a steel roof and doors, the Murcielago’s body was already carbon fiber from tail to tip, so much of this weightloss came from a redesigned exhaust system. This fat-slimming also raises the SuperVeloce atop its class in power-to-weight ratio, which most supercar manufacturers will tell you is the next frontier in performance schematics. Sure power and torque will continue to increase, but the next big leaps in performance will come more from designers stripping weight from a vehicle than from boosting its power output. It’s why burners like Nissan’s 370Z are improving performance by getting lighter and smaller than their predecessors, instead of simply cramming more pistons into their engine bays.

Of course, the SuperVeloce may have shed 200 pounds, but its still thirsty as ever: expect no more than 6/14 mpg highway/city. Sluurrp!
