Chris Harris hits the track in the Porsche 911 GT3 RS

One of the wonderful things about Chris Harris on Cars is the enthusiasm that the host brings to the screen. Granted, it would be hard not to enjoy a day driving around in a supercar that you don't own. Still, Harris brings a sense that he knows how rare these opportunities are and relishes them. In his latest look at the two sides of the latest Porsche 911 GT3 RS, you can tell this guy is having a lot of fun. The GT3 RS is a 500-horsepower, track-focused weapon, but it's expected to drive to and away from the circuit after a day of laps. Therefore, Harris decides to evaluate the attributes of this Porsche in both environments. On the road, he sweeps an orange example over some beautifully, undulating German backroads but keeps things rather tidy. However, in the latter half of the video, he arrives at the Weissach test track for a go in a purple RS. There, he really lets the rear hang out.

One Lap of America, with three times the madness

Instead of celebrating last weekend face down in a sombrero full of tequila-spiked OJ and a few lime wedges, 71 racing teams with one set of tires each and no support crews began Cinco De Mayo — and this year's 35th running of the One Lap of America — by hitting the wet skid pad at Tire Rack's headquarters in South Bend, Ind. There were Porsches, Vettes, Camaros and BMWs galore. There was a Miata, a vintage NSX, a Honda S2000 and even an old VW Rabbit. There were GTIs, the odd Evo and, oh yeah, six Toyotas, a couple of Vipers and a couple of GTRs. When the skidding stopped, a 2011 BMW 1M emerged triumphant and led the pack out into the heartland, where it will spend 5,000 miles this week hitting road courses, dragstrips and time trials at tracks as far west as Denver, as south as Fort Worth and then New Orleans. From there, it will barrel north through Mississippi, Alabama, Nashville, Kentucky and back home again to Tire Rack in Indiana. Twenty events, eight venues, with a three-hour window for each event. It's a nonstop, no-sleep, one-week road trip comprising 150-ish friends and brothers, partiers and pro racing drivers, spouses and other family-member combo packs. Some will never speak to each other again, some might end up divorced, some might get married. All of them are nuts. I know this because I made three laps. Three laps I will never forget.LAP ONE: 1984 Vehicle: 1984 Dodge Van Team #0: Jean Lindamood (Jennings), Walker Evans, Parnelli Jones I was present for the inaugural 1984 One Lap of America because I worked at Car and Driver back then and so did Brock Yates. He was the guy who came up with the clandestine, illegal, unsanctioned Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash from Connecticut to Redondo Beach, Calif. It ran five times in the 1970s, with Yates joining Dan Gurney in a Ferrari Daytona for the second run. They won, Gurney insisting that "at no time did we exceed 175 miles per hour." One Lap was born of Cannonball nostalgia (read: Brock was bored), and I was beyond game for it. After securing a van from Dodge and two giant decals for the van sides, along with $5,000 in sponsorship from local Detroit Stroh's Brewery, I coaxed my friend, nine-time Baja 1000 winner Walker Evans, into running One Lap by suggesting he didn't have a hair on his ass if he refused. Then I suggested that if he didn't get his best friend and longtime road trip buddy, Parnelli Jones, to go with us, I would actually have to drive the van, too.

Mercedes-AMG GT S pit against Porsche 911 Turbo in Evo Deadly Rivals test

When Mercedes-Benz announced that its all-new AMG GT would start at $129,900 deeply undercutting the $200,000-plus of its predecessor, the SLS AMG, immediate questions focused on how it'd stack up against the latest crop of high performers that occupy the mid-$100,000 range. Evo, over in the UK, didn't have to wait all that long. The latest installment in the outlet's "Deadly Rivals" series compares the AMG GT with the latest Porsche 911 Turbo. On paper, the test is sure to be interesting. The Mercedes uses a 4.0-liter, twin-turbocharged V8 with 503 horsepower and 479 pound-feet of torque, while a seven-speed AMG Speedshift dual-clutch shuffles power to the back axle. The 911 Turbo's formula is more of a known quantity – 520 hp from a twin-turbo, 3.8-liter flat six with the company's own PDK working in unison with all-wheel drive, torque vectoring and rear-axle steering. Of course, we're not going to spoil the results for you. Take a look at the video up top, and let us know what you think of Evo's latest track battle.
