Porsche 911 with VW turbodiesel prepares for LeMons assault

LeMons racing is a wonderful example that setting limits can actually breed creativity. The series mandates that all entries must cost $500, not counting safety equipment, and that cap forces teams to be ingenious in how they build a racecar. Take for example this diesel-powered Porsche 911, which its creators have dubbed Ferkel the Nein-11, that will be racing in the Sears Pointless race this weekend in Sonoma, California.
This Frankenstein combines a 911 chassis that was originally bought just for its European powertrain and a Volkswagen TDI diesel engine mounted in the rear. After deciding the shell could still be of some use, the team decided to go racing. "We began brainstorming what replacement drivetrain to use for maximum offense and there was really only one answer: a diesel," said Philipp von Weitershausen, one of the team captains, to Jalopnik. They bought a 1998 Jetta TDI on the cheap and started figuring out a way to hack the engine into the bay. To pay respect to the donor, the VW's trunk was highly modified (and drilled) and grafted onto the back of Ferkel.
This team isn't a newcomer to LeMons. Its last car was a classic VW Beetle with a Subaru engine and dual controls, named Ferdinand the Bug, which could be driven from the left or right side. It's quite a sight.

Porsche 911 R is made for the purist

Who wouldn't welcome a new version of the Porsche 911 with ultra-light weight, a GT3 RS motor, a stripper interior, and a core philosophy of driving fun over outright lap times? The iconic Porsche 911 has been getting larger and more complicated with each passing generation, and that hasn't sat well with every engineer at Porsche. So there's a ready market out there for 911 R, a limited-edition show stopper of just 911 cars, due to start production in Zuffenhausen, Germany, in May. It's a car that combines a unique version of the six-speed manual gearbox, plenty of raw, naturally aspirated flat-six power, and all the feel of a cut-price version of the 911 GT3 RS pseudo racer. Yes, Porsche is bringing the beloved six-speed stick back to the sharp end of the 911, even though the brand's quickest cars are now dominated by the seven-speed dual-clutch transmission (and the less loved seven-speed manual). Porsche insists that the RS is still the 911 to have if it's stopwatch-bashing you need to do. Instead, the 911 R developers focused on trying to give it the most driving purity it could cram in. The most traditional way for motorsport operations to do that has always been to rip out weight. And Porsche Motorsport didn't diverge from the plan. The 911's rear seats have been thrown out, along with a raft of other pieces Porsche Motorsport thought it could either do without completely, redesign to be lighter or stronger, or both.

The pound-cutting starts at the body and bores all the way into the 911 R's chassis components, though there are some obvious nods to the marketing department that survived the dietician's axe. There is a lot of 911 GT3 in the body, with a combination of a carbon fiber (bonnet and front guards), a magnesium roof, polycarbonate front and side "glass," and aluminum everywhere else. The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. While the 911 R has lurid (and deletable) red or green racing stripes as standard, it's not supposed to be as wild looking as the GT3. Porsche replaced the GT3's adjustable, tall-standing rear spoiler with a more-subtle pop-up version, and the R uses a rear diffuser under the bumper to offset any loss of rear downforce. The rear seats are gone, and the two remaining seats use carbon fiber shells upholstered in tartan cloth (another nod to early 911s).

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
