Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Genesis cars win accolades, offer value — so why are sales so bad?

My high-school buddy Brent Cormier was so smitten with the Genesis G80 when he saw it at an event I hosted at SXSW in 2016 he bought a used 2013 Hyundai Genesis a short time later and fell in love with the car. "It surpasses my every expectation," said Cormier, a self-described "renaissance man" who owns and runs a real estate agency with his wife Laura, is a food service executive chef and part owner of Austin-based Thin the Herd Guitars. "I was locked into Mercedes and Audi for 10 years," he added. "And felt trapped in an endless pit of maintenance costs." After owning the Genesis over the past two years — including using it as an Uber and Lyft driver to earn extra cash — Cormier learned what some frugal luxury sedan buyers and a handful of car reviewers have discovered: Genesis offers great bang for the buck compared to other premium brands and can compete with the best in terms of performance, features and comfort. Hyundai's luxury brand also earned a prominent third-party endorsement last week when for the first time Genesis topped J.D. Power's 2018 APEAL study, surpassing German luxury-performance icon Porsche. The APEAL study (which stands for Automotive Performance, Execution and Layout) "measures owners' emotional attachment and level of excitement across 77 attributes," ranging from performance to comfort, and asks nearly 68,000 owners of new 2018 models to score vehicles on a 1,000-point scale. In its second year ranked as a stand-alone brand, Genesis earned an APEAL score that bumped it up 15 points to 884 and helped push it past Porsche — and past BMW, Lincoln, Mercedes-Benz, Audi, Volvo, Cadillac, Land Rover and Lexus, in order of ranking. Last month, Genesis also topped J.D. Power's Initial Quality Survey (IQS) for the first time this year. And both its models were awarded Top Safety Pick Plus ratings by the Insurance Institute for Highway Safety, among 11 Plus ratings in all for Korean vehicles. Despite high J.D. Power rankings and great reviews, Genesis U.S. sales were off 50 percent for the first six months of 2018 compared to 2017, and in June Genesis sold only 796 vehicles — the first time U.S. numbers dropped below 1,000 in a month. Part of Genesis's APEAL and IQS success can be attributed to its small product lineup: just two models, the G80 and G90 sedans, with a third, the 2019 G70, launching later this year. And while those numbers may help in J.D.

Roger Rodas' widow suing Porsche over Carrera GT crash

Investigations undertaken by local law enforcement may have vindicated Porsche from any wrongdoing in the crash that killed actor Paul Walker and racing driver Roger Rodas last year, but the latter's widow is apparently not convinced. According to emerging reports, Kristine Rodas has filed a lawsuit seeking unspecified damages from Porsche Cars North America.
In her suit filed with the Los Angeles Superior Court, Rodas' attorney Mark Geragos reportedly disputes the findings of the Los Angeles County Sheriff's Department, which asserted that the vehicle was traveling at an unsafe speed of 90 miles per hour on city streets, identifying the speed as the cause of the accident. Instead the lawsuit claims that the vehicle was only going 55 mph and that the cause of the crash was improper equipment - namely a faulty right rear suspension and the lack of a crash cage and proper fuel tank.
