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.

Kia's Intelligent Manual Transmission — here's how iMT and clutch-by-wire works

When Kia introduced the facelifted Rio for Europe a few weeks ago, the press release briefly touted a clutch-by-wire six-speed manual transmission that would improve gas mileage and reduce CO2 emissions. A new press release provides details on the Intelligent Manual Transmission (iMT), which we find a surprising avenue of innovation designed just for mild hybrids. Traditional and dual-clutch automatic transmissions, thanks in part to more gears and programmed repeatability, already perform better than human drivers shifting for themselves in metrics including gas mileage. Kia's head of powertrain in Europe said the automaker developed the manual just because "European drivers in particular still love changing gear for themselves." With the pressure on budgets and on standard gearboxes even before the current travails, this seems a benevolent gesture. The traditional linkage from clutch pedal to gearbox goes AWOL in the iMT, sensors on the pedal lever controlling clutch actuation electronically. And an iMT-equipped Kia can take over control of the driveline even when the vehicle is in gear. For example, when a driver takes his foot off the accelerator as he approaches a stoplight, the iMT tells the mild hybrid system to turn off the engine, as it disengages the clutch. Normally, many drivers use coasting in gear in this situation as a way to slow the car without pressing the brake pedal. Kia's system has "the open clutch limiting deceleration and allowing the car to make the most of its kinetic energy," which will mean rethinking one of the finer points of transmission use. If the driver presses the accelerator or brake during the coast, the integrated starter-generator (ISG) restarts the engine. Assuming speed hasn't dipped too low for the chosen gear, the iMT engages the clutch and the driver resumes in the gear the Kia was left in. The hybrid system supplies a boost to get engine revs back up to speed in order to avoid bogging. If vehicle speed is too low to avoid bogging in the current gear, the iMT will disengage the clutch so the car effectively restarts in neutral while in gear, and the driver adjusts.

Kia unveils SP Signature concept at Seoul Motor Show

The Seoul Motor Show is alive and kicking, and Kia has used its home event to display two new concepts. One is the Mohave Masterpiece large SUV, which is what our Borrego could have become if the Borrego hadn't been sent to slaughter in 2009 after just one year on sale here. The other concept is the SP Signature, said to preview a compact crossover Kia will sell around the world starting later this year. The four-door is a toned-down, more production-ready version of the SP concept unveiled at India's Auto Expo last year. The car's a bit of a cryptid, with few facts and plenty of fuzzy details to go on. The SP Signature concept apparently began as an Indian-market product, then morphed into a worldwide offering. Kia said the "SP Concept hints at the company's plans to introduce a new small SUV for its global markets," but that "hint" has already been confirmed; Kia Motors CEO Han-Woo Park told Automotive News last October that the U.S. would get a new compact crossover in late 2019, and a prototype matching the Signature's profile has been spotted testing. Slotting in below the Sportage and about the size of the Hyundai Kona, the reported retail name is Tusker, but we aren't sure that name will apply here. Although the Signature evokes Kona vibes, detailing makes the Signature look more technical and hawkish than the Kona, which we like. Rumor also has it that the so-called Tusker won't include all-wheel drive as an option so as to leave daylight between it and the Sportage. Several outlets have posited a debut at the New York Auto Show, partly because the N.Y. show put out a press release listing Kia as one of the automakers with a world debut. That press release has since disappeared, and with Hyundai having announced the even smaller Venue crossover for New York, it's possible Kia could have to give way to big brother.
