Porsche not responsible for Paul Walker and Roger Rodas crash

A US District Court judge has found that Porsche wasn't responsible for the Carrera GT crash that killed Roger Rodas and actor Paul Walker, according to The Detroit News citing the Associated Press. Rodas' widow, Kristine, brought the lawsuit against the German automaker, but the court ruled there was a lack of evidence for her case. "Plaintiff has provided no competent evidence that Rodas' death occurred as a result of any wrongdoing on the part of defendant," US District Judge Philip S. Gutierrez ruled, according to the AP. Rodas' lawyer pledged to appeal the decision. Rodas' lawsuit asserted that the Carrera GT's right rear suspension failed and also cited the Porsche's lack of a proper fuel cell or a crash cage as factors. However, the judge didn't see any evidence for the suspension failure. He also criticized the expert for Rodas' side for analyzing tire marks from over a month after the crash rather than the photos from right after the incident, the AP reports. A 2014 investigation by the Los Angeles County Sherriff's Department blamed unsafe speed as the fatal accident's cause. The investigators reported that the Carrera GT was doing between 80 and 93 miles per hour when the crash happened. They also found nothing mechanically wrong with the supercar but did discover that the tires were over nine years old. The LA County Coroner ruled that both deaths were accidents. According to the AP, the lawsuits from Walker's daughter and his father against Porsche are still pending in Los Angeles Superior Court, and the district court ruling doesn't affect them. In each case, Porsche denied being at fault and cited the sheriff's investigation as support for that argument. Related Video: This content is hosted by a third party.

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.

Bugatti and Rimac joint venture profitable 'beyond expectations'

WARWICK, England — The joint venture between Croatian electric carmaker Rimac and Bugatti has been far more profitable than anticipated as the two brands work on developing vehicles together under one roof, Rimac's top executive said on Wednesday. "It's highly profitable and cash flow positive beyond anybody's expectations," Rimac CEO Mate Rimac told Reuters in an interview at the UK offices of the carmaker's Rimac Technology unit in Warwick. "It's such a win-win situation for everybody." Rimac added the joint venture has brought "lots of synergies going both ways." The Rimac Group comprises the Bugatti-Rimac JV, producing the electric sportscar Nevera and the Bugatti Chiron — which is owned 45% by Porsche AG — and a technology unit which supplies battery systems and powertrain components to other carmakers. Earlier this year the group raised 500 million euros ($519 million) in a new funding round. Rimac's CEO said the company has developed a "really close strategic relationship" with Porsche, which was listed by its parent Volkswagen in October. Porsche holds a 20% stake in the Rimac group. "We are really collaborating on many levels, developing and producing lots of key elements of their (Porsche's) future hybridization and electrification," he said. Rimac's CEO said the group must become more like Ferrari with a predictable, stable and profitable business before it can contemplate an initial public offering. "They (Ferrari) make projections and they always achieve," he said. "What I want to have is some kind of stability and certainty before we do an IPO because we don't want to make promises we can't keep." An IPO could happen anytime from three years to a decade from now, and could involve going public as a group or spinning off a unit, he said, but is definitely coming because "we obviously have financial investors that at some point want to exit."
