Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:

Jeep Grand Cherokee SRT gets power increase, minor tweaks for 2015

As a brand within Fiat Chrysler Automobiles, SRT may have an uncertain future, but it's pumping out some seriously mean machines anyway. The supercharged Hellcat V8 may be gobbling up most of the headlines with its 707 horsepower, but even the Grand Cherokee SRT is getting some small updates for the 2015 model year.
Most importantly for many enthusiasts, the Grand Cherokee SRT is getting a slight power bump. Don't expect the 700+ hp from the Hellcat, but this SUV sees a modest 5-hp and 5-pound-feet of torque improvement to bring output to 475 hp and 470 lb-ft for its 6.4-liter V8 with an eight-speed automatic. The minor change doesn't change the sprint to 60 miles per hour, clocking in at the same 4.8 seconds, or the tow rating at 7,200 pounds. Still, more grunt is never a bad idea.
Another new addition is the Active Noise Canceling system as a standard feature for this powerful SUV. It adds four microphones around the vehicle and uses the stereo system to nullify extraneous sound. However, Jeep claims that the meaty exhaust note from the V8 still gets through into the cabin for driver enjoyment.

Vile Gossip: Ladies who launch

We were driving a Bugatti Veyron 16.4 across the Florida Panhandle from Jacksonville to Panama City, only because I couldn't convince Bugatti to let me be the first to drive its exotic powerhouse, the world's fastest car at that time, all the way across America. One gleaming example had arrived in time for the Amelia Island Concours d'Elegance, where the journos massed for their quick test drives out the front drive of the Ritz Carlton, down a short stretch of the A1A, and back to the Ritz. Not far enough for me. I wanted to take the Veyron in all of its 16-cylinder, 1,001-horsepower, $1.3-million-dollar glory on a coast-to-coast extravaganza of a road trip. Never hurts to ask. I asked. Once the Bugatti guys stopped hyperventilating, I explained that the coastal adventure would be contained wholly within the state of Florida, from the Atlantic coast to the Gulf of Mexico. My secret destination, however, was to be Vernon, Florida, home of the great Errol Morris' classic documentary about a town in the Panhandle with the highest per-capita population of citizens who'd blown off or whacked off a limb for insurance money. (Google "Nub City.") The Swiss head of Bugatti public relations thought it hilarious. He showed up in a van with a couple of German mechanics to follow us and a failed French Formula 1 driver to serve as my chaperone. I came with a photographer from Germany and one of the most infamous of bad-boy auto magazine tech editors, the irrepressible Don Sherman. Sherman had his own reason for going, and it had nothing to do with a Veyron to Vernon. Once we gave up looking for nubbies, he ordered me to veer south to the handgrip of the Panhandle, familiarly known as the Redneck Riviera. The Don was aiming to secretly execute the Veyron's first Launch Control blastoff in captivity.
