Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events."

No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.

Porsche Cayenne diesel V8 may not be long for this world

Goodbye, Porsche Cayenne V8 Diesel. We hardly knew ye. Nor did the Europeans, apparently. Porsche's V8 oil burner is still on the European model list for the Cayenne SUV, but the mill won't go through the likely pricey process of being updated to adhere to new and stricter European emissions standards, Just-Auto says. A Porsche spokesman confirmed to the publication that it's a fairly complicated process to update the diesel V8 to be so-called "Euro-6 compliant." With Cayenne diesels selling in relatively low volumes anyways, the German automaker might just dump the V8 diesel altogether, as it'd be quite cost-ineffective to make the necessary upgrades. The V8 diesel was a 4.1-liter engine that delivered 385 horsepower in addition to what sounds like a little too much exhaust for European clean-air regulators. While that's a pretty powerful profile, the most recent gas-powered V8 for the Cayenne delivers about 570 horsepower, so the diesel engine won't likely be missed by European auto enthusiasts. Besides, there's still the V6 diesel that's also sold in the US. That's a 4,800-pound beast that moves from 0 to 60 miles per hour in about seven seconds and gets a relatively (for diesels) modest 20 miles per gallon city. For those who are curious, Autoblog's First Drive review of that model can be found here.

Porsche 911 GT spied streaking at the Nurburgring

At any given moment, you can bet that Porsche is testing some new version of the 911. When we see those prototypes undergoing testing, they're typically camouflaged, at least in part, to keep us from seeing what Zuffenhausen (or Weissach) is up to. But this particular example is completely undisguised. So what are we looking at, exactly? Well, for starters, it's likely the upcoming facelifted version of the current 911. The current 991 generation has been on the market now for four years, so the 991.2 (or 991.5, perhaps?) will likely be tasked with keeping Porsche's iconic sports car current for several more years to come. This version can be seen with front air intakes similar to those on the Cayman GT4, along with updated headlights, LED strips, new door handles, ventilated rear engine cover, reprofiled rear bumper, fresh taillights, and a new exhaust. The far bigger development is that the updated 911 is expected to ditch natural aspiration in favor of downsized turbocharged engines across almost the entire range – not just in the 911 Turbo. This particular version we see here, however, could be one of the few hold-outs for atmospheric pressure. That's because what we're looking at could be the upcoming back-to-basics version being prepared by the GT division – the same outfit responsible for the 911 GT3, GT3 RS, and Cayman GT4. Possibly adopting the name GT5, this new version of the 911 is anticipated to be the purist's choice: naturally aspirated flat-six, three-pedal manual transmission, skinny tires, no frills. This undisguised prototype appears to be packing a production roll cage and thin, leather-clad bucket seats – splitting the difference between racing buckets and the usual, thicker thrones. We'll have to wait a bit longer until Porsche is ready to release all the details of the refreshed 911, hopefully to include that GT version. But for an unadulterated taste of what's to come, look no further than the spy shots in the image gallery above. Related Video:
