Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:

Lamborghini Huracan Performante's active aero is the secret to its speed

The most revolutionary real technology at this year's Geneva Motor Show didn't look like it on the show stand. If you squint at the Lamborghini Huracan Performante, it merely looks like a Huracan with a big wing. Up close, you can see the fractal texture of the forged-composite aerodynamic add-ons, but that still doesn't tell you why this car is so special. Lamborghini calls it Aerodinamica Lamborghini Attiva (ALA), or active aerodynamics. This is one of the biggest keys to the Performante's claimed production-car record lap time at the Nurburgring Nordschleife of 6 minutes, 52.01 seconds. The Huracan Performante's number is not without controversy, but I personally care very little about the obsessive phallic-measuring contests that are 'Ring lap times. What's fascinating about the Performante is that, if the lap time is even close to legitimate, it shows that ALA is a major step forward in automotive performance. More than just lap times, the Huracan Performante is an example of why Lamborghini remains special in a world of democratized performance. We sat down to discuss this with Lamborghini's Research and Development Director, Maurizio Reggiani. And one last note on the lap time: Reggiani says with the same temperature and exclusive access to a dry track, "that in this average of speed we can repeat, repeat, repeat, repeat." In previous conversations, Reggiani said that the key difference in performance would come not from horsepower, but weight reduction. For Lamborghini, that means plenty of carbon fiber. But the newest Huracan is not a Superleggera, the old title for the hardcore variant. "Superleggera is too much an objective, a description. Performante is really the DNA of the car. In Italian, Performante means really the best performance," he said. Reggiani continues, "Nothing happened by chance. It's really a building-block approach where you say this can give this contribution, this can give that. Where can you improve something and what is needed to improve something?" That brought them to the active aerodynamics solution, which channels air to stall the front or rear aero elements of the car to change the downforce and drag. Reggiani says, "This can be achieved only with a system that is really light, [has] fast responsiveness. Based on this ...

Jay Leno holds Lamborghini showdown, compares Gallardo LP570-4 and LP550-2

Jay Leno's Garage welcomes two of our favorite Lamborghini models over for compare-and-contrast session, the Gallardo LP570-4 Superleggera and Gallardo LP550-2. Note, however, that these are the 2012 coupes, not the 2013 models with their revised front and rear fascias.
Leno likes the size of the Gallardo over the Aventador, and between the two siblings, his philosophy leans heavily toward the rear-wheel drive and superior comfort of the LP550-2. With the help of Andrew Romanowski of the Lamborghini Club of America, Leno goes through little-known details like the LEDs in the engine bay and the particulars that distinguish the two vehicles like the Alcantara, polycarbonate windows and lighter tires on the Superleggera.
Then, doing something that he would never do with human guests on his television show, he takes his favorite out for the driving segment and leaves the all-wheel-drive coupe at the garage to pout. You can learn a few things yourself and listen to Jay sing hosannas about the overall build quality and rear-focused power of the LP550-2 in the entertaining video below.
