Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

Nissan bringing Qashqai, Rogue hybrid to US

Nissan will be expanding its crossover range here in the United States, introducing the popular European-market Qashqai, alongside a hybridized version of the Rogue. Nissan's Kyushu, Japan factory, meanwhile, will churn out 100,000 gas-powered Rogues to capitalize on hot demand here in the United States. The Kyushu move, at least, seems like a smart one, considering just how hot the compact Rogue is. "We haven't hit the ceiling [on Rogue] yet. We have more opportunity there if we can get our dealers more," Fred Diaz, Nissan's senior VP of sales and marketing, told Automotive News. Amping up production in Kyushu will finally mean the end of the first-generation Rogue, though, now known as the Rogue Select. Somehow, we doubt many tears will be shed. AN cites "two sources familiar with Nissan's future product" in its report on the Qashqai and Rogue Hybrid, although both moves are a bit strange at first glance. Both vehicles play in the same part of the market, and are both based on the Renault-Nissan Common Module Family platform. As for the Rogue Hybrid, well, we know what happened the last time Nissan tried to add an electric motor and battery pack to one of its crossovers. Plus, we've heard this rumor before. Nissan, though, seems to think both moves make a lot of sense. While the Qashqai and Rogue are closely related, the Euro-market model is smaller – 10 inches shorter and two inches narrower – making it less versatile, and it wears more handsome sheetmetal. Expect Nissan to field it as such, aiming at buyers that want a CUV for the lifestyle, rather than the versatility, Automotive News reports. There's a lot less information on the Rogue Hybrid, aside from AN reporting that it will hit the market next year. As for potential powertrains, mum's the word. The gas-powered Rogue uses a 2.5-liter four-cylinder, which is the same size as the gas-engine found in the dead-but-still-warm Pathfinder Hybrid. While we doubt it's as simple as a drag and drop, it seems like Nissan's most recent hybrid powertrain is the obvious choice for the upcoming Rogue. What do you think? Will the Qashqai be as big of a hit in the US as it is in Europe and Australia? Is a Rogue Hybrid such a smart move considering the tremendous failure of the Pathfinder Hybrid? Speak up in Comments.

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.
