Lamborghini launched the Murcielago way back in 2001 on the slopes of Mount Etna in Sicily. The volcano was smoking gently as we flew in, and as we drove up the mountain some of the lava from an eruption mere weeks earlier was still cooling. It wasn’t hard to figure out the subtext here: This car is meant to be intimidating. Handle with care. Which is why the LP670-4 SV is such a surprise. It’s the lightest, most powerful, fastest Murcielago ever built. Yet it allows us mortals to tip-toe closer to the very edge of its truly volcanic performance envelope than any big-banger Lambo in history. If any $450,000, 661-horsepower, 212-mph, hip-high wedge of weapons-grade testosterone could ever be called a pussycat, this is it. Well, up to a point.
