LAMVORGHINI MURCIEALGO SV LP670-4 vs AVENTADOR SV LP750-4

             MURCIELAGO SV LP670-4
SuperVeloce, or SV, is a storied name in Lamborghini’s history, seen most recently on the 1995–99 Diablo SV. The moniker is usually applied to a more powerful, gussied-up version of a car that’s near the end of its life cycle, which is what we have here in the Murciélago LP670-4 SV.
Compared with the plebeian LP640, the SV’s version of the 6.5-liter V-12 develops 29 more horsepower—up from 632 to 661—owing to revised valve timing and modifications to the intake system. Torque is unchanged at 487 pound-feet. The more powerful engine doesn’t have to work as hard, either, as Lamborghini has sliced off a claimed 220 pounds, mostly through the extensive use of carbon-fiber panels and interior parts, and a lighter exhaust system. As a result of higher power, lower mass, and quicker electronic gearchanges, we expect the SV to rip from 0 to 60 mph in 3.0 seconds en route to a claimed top speed of 213 mph with the optional small spoiler, or 209 mph when equipped with the lofty “Aeropack” wing.

Despite sacrificing top speed, serious drivers will opt for the Aeropack because the big fixed wing creates so much downforce that Lamborghini should consider changing the name to SG, for Super Glue. On the 16-turn, 3.9-mile handling track at the Nardò proving ground in southern Italy, the SV’s rear end always remained firmly planted, in contrast to the base Murciélago’s occasional booty shake around tight corners.

Notwithstanding much improved behavior on the handling course, the SV felt most at home on Nardò’s nearly eight-mile-long high-speed circle. “We tuned the steering for high-speed sensitivity,” says Maurizio Reggiani, head of Lamborghini R&D, and the resulting on-center feel is precise and responsive at what would be liftoff velocity for most aircraft. Following the upper lane around the big Nardò ring’s gentle arc is point-and-shoot simple—the broken white lines simply whiz by faster.

On a whim, we nudged the speedometer near 340 km/h (211 mph), at which point our passenger, a Lamborghini Driving Academy instructor, raised and lowered his left hand, a gentle reminder to return to the posted 240-km/h (149 mph) limit.
Decelerating the SV inspires confidence, too. Standard 15-inch carbon-ceramic discs with six-piston calipers at all four corners (optional on the LP640) stand at the ready behind lightweight, glossy-black 18-inch wheels. The brakes are aided by the huge rear appendage, which also acts as an air brake. To coast to a crawl, simply lift off the throttle and let drag take over.
Production will be limited to 350 cars, with a price that’s likely to be nearly $100,000 more than the base LP640’s already lofty $361,400 sticker. Even so, the SV offers more performance than a REVENTON,for about a third of the price.

 

             AVENTADOR SV LP750-4

The term “hot commodity” doesn’t even begin to describe the Lamborghini Aventador LP 750-4 Superveloce. Just three months after it was revealed at the Geneva Motor Show, the SV-spec model has already achieved sold-out status.  While not all of the 600 planned units have been produced, each and every one of them has been pre-sold. 200 units are scheduled for North and South American delivery, another 200 are headed to Europe, the Middle East, and Africa, and the final 200 supercars will ship off the Asian Pacific countries.  Priced from €327,190 in Europe and $493,069 in United States, the more powerful, better handling, and more aggressively-styled Aventador SV also shaves 110 pounds off the standard Aventador’s belt line.  Related: The Lamborghini Aventador SV Laps the ‘Ring in Under 7 Minutes
As the name suggests, the LP 750-4 developed 750 horsepower — 50 more than the normal car. Thanks to its aerodynamic upgrades, the SV is 150% more efficient at cutting through the air, and adds an extra 70% of downforce. These tweaks add up to a 2.8 second sprint to 60 mph and a top speed of over 217 mph.
The Lamborghini Aventador Superveloce is rivaled by models like the Ferrari F12 Berlinetta and Pagani Huayra. The F12 develops 740 hp and 508 pound-feet of torque from a 6.3-liter V12 while the Huayra uses an AMG-sourced twin-turbocharged V12 with 720 hp and 740 lb-ft of torque on tap. The F12 gets to 60 mph in 3.1 seconds and the Huayra falls behind both the F12 and Aventador SV with a 3.2 second sprint.

Most most to least unique, the Huayra costs $1.4 million and only 100 models have been built. The Aventador SV is the next most expensive and rare, while the F12 seeming like a bargain at $350,000.
Without any more hardcore Aventador versions being planned, the LP 750-4 SV may maintain its status as the most powerful production Lamborghini –besting the Veneno LP740-4– for a good while.
