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.

2014 Nissan Pathfinder Hybrid

If you've been keeping up with our long-term 2013 Nissan Pathfinder coverage, you already know that, generally speaking, we dig it. After racking up 21,000 miles (and climbing!) on our dear Sweet Brown, we've become very, very familiar with the Pathfinder package as a whole, and many of us actually prefer it over competitors like the Ford Explorer and Chevrolet Traverse.
For 2014, Nissan has added a new hybrid option for its Pathfinder, using an all-new powertrain that will also be shared with the CUV's Infiniti-badged QX60 sibling. As far as fuel economy is concerned, our long-term Pathfinder has had no problem hitting its EPA-estimated numbers of 19 miles per gallon city and 25 mpg highway, but this new hybrid model is said to be good for an increase in overall economy - 25/28 mpg (city/highway) when equipped with front-wheel drive and 25/27 mpg with optional four-wheel drive.
We recently took the 2014 Pathfinder Hybrid for a quick spin around the city streets of Nashville, TN. And while our time with the non-hybrid Pathfinder has been pretty enjoyable overall, at first blush, we're having a tougher time warming up to this electrified variant.

Automakers can, and do, use your private information however they want

The first paragraph of Mozilla’s *Privacy Not Included" buyerÂ’s guide about car privacy issues is worth repeating here: “Ah, the wind in your hair, the open road ahead, and not a care in the world Â… except all the trackers, cameras, microphones, and sensors capturing your every move. Ugh. Modern cars are a privacy nightmare.” “Ugh” may be an understatement. The crux of the matter is control: The nonprofit Mozilla Foundation has found that vehicle manufacturers have collected tons of “private” data from vehicle operators, thanks to the proliferation of sensors and cameras and smartphones connected in and to cars. In its report, Mozilla found that 25 car brands all failed the consumer privacy tests it carried out. Its research found that 84 percent of car companies review, share or sell data collected from car owners, and that the information was used for reasons unrelated to the operation of a vehicle or to a car brandÂ’s relationship with its owners. And beyond that, the report says that many companies — more than half — “say they can share your information with the government or law enforcement in response to a 'request.' Not a high bar court order, but something as easy as an 'informal request.'” Some other points made by the foundation: — Six car companies can collect intimate information, including a driverÂ’s medical information and genetic information. Plus info about how fast a person drives and the songs he listens to in the car. — Nissan earned its second-to-last spot (Tesla, not surprisingly, was worst) “for collecting some of the creepiest categories of data we have ever seen": In an apparent attack of full disclosure, Nissan said that it can share “inferences” drawn from the data to create profiles “reflecting the consumerÂ’s preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, and aptitudes.” It also collects information about “sexual activity.” It's not clear how they can do that, but in their privacy notice they say they could. Not to be outdone, the report says, “Kia also mentions they can collect information about your 'sex life' in their privacy policy.” — Only two of the 25 brands reviewed, Renault and Dacia, stated that drivers had the right to delete their personal data. The brands are headquartered in Europe, where consumers are protected by General Data Protection Regulation privacy laws.
