Kaz and Shiro talk Gran Turismo 7 details, Titan Nismo and more in AMA

One of the greatest innovations to come about thanks to the gigantic popularity of Reddit is the Ask Me Anything (AMA) question and answer format. The AMA becomes especially worthwhile, of course, when the person(s) answering the questions have detailed information or insight on products we love.
So, in the case of the recent AMA session with Gran Turismo creator and mastermind Kazunori Yamauchi (above), and his buddy and Nissan chief designer Shiro Nakamura (right), it was basically must-read stuff.
The pair really lived up to our expectations, too, with Kaz offering a lot of useful information about the future of the Gran Turismo franchise (especially the upcoming GT7 for Playstation 4), and Shiro promising to bring some interesting new ideas back to his colleagues at Nissan.

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.

2018 wrap-up, Ford Ranger and Mercedes A-Class | Autoblog Podcast #566

In the final Autoblog Podcast of 2018, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Associate Editor Reese Counts. They kick off the conversation by talking about a couple of hot new vehicles: the Ford Ranger and Mercedes-Benz A 220 4Matic. Then they round up the biggest stories of 2018 before helping a listener choose a new car in the "Spend My Money" segment. Thanks for listening, and happy holidays.
