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.

Subprime financing on the rise in new car sales, leasing too

We all remember the financial crisis that began several years back. At its core was a splurge of subprime lending for housing loans. The housing bubble burst, triggering a collapse of the mortgage-backed securities market. Apparently, those types of loans still exist in the automotive industry, and the market share for these types of "nonprime, subprime, and deep subprime," loans has grown 13.6 percent compared to the third quarter a year ago.
According to an Automotive News report, high-risk lending expanded to 24.8 percent of total loans in Q3, up from 21.9 percent for this time last year. As this level increased, average credit scores of borrowers dropped to 755, down from 763 a year ago. In that time, the average financing amount increased $90 per vehicle, to $25,963.
At 818, Volvo maintains the highest per-owner credit score, while Mitsubishi has the lowest, at 694. The highest rate of borrowers was at Toyota, with 14 percent of the market, followed by Ford with 13.1 percent and Chevrolet at 11.1.

Corvette Z06. Nissan GT-R Nismo. Motor Trend Head 2 Head. 'Nuff said.

Here is a video we've been waiting for, one that will get broadband fiber optic cables glowing like Hooker headers on a dyno. For Episode 62 of Head 2 Head, Motor Trend throws the 2015 Chevrolet Corvette Z06 into the bear pit with the latest Nissan GT-R Nismo. What comes out of that is seventeen minutes of don't-look-away video. We're only going to give you the specs. The 3,527-pound Z06 gets on with a supercharged 6.2-liter V8 with 650 horsepower and 600 pound-feet of torque, applied to the wheels via a seven-speed manual transmission. With the Z07 performance package appended it has a front splitter and winglets, and a three-section rear spoiler among its aero aids. The tested model also wore carbon ceramic brakes, which helped push its $89,985 MSRP out to $105,210. The 3,881-pound GT-R Nismo plays the underdog – again – with a 3.8-liter twin-turbo V6 spitting out 600 hp and 481 lb-ft, yoked to a six-speed dual-clutch transmission. The GT-R left its 'performance bargain' days behind years ago, and this top-shelf version starts at $151,585 but has almost everything it can get, so the as-tested price was only a skosh more at $151,880. We're not going to tell you any more than that. Click on the video and let Carlos Lago and his two mean minions tell you a story you won't soon forget.
