Super Bowl car commercials: Follow along as we riff on them live

Join Autoblog editors Sunday starting around 6:30 p.m. ET as we react to all of the car commercials during the game. We know Hummer, Porsche, Hyundai and others will have splashy ads, and naturally, there's usually a few surprises. Whether you're a Chiefs or 49ers fan — or don't care about football — the commercials are always a highlight. And for us, the car spots are the most intriguing. Weigh in with your own thoughts in the comments section. Let's kick off.   FIRST QUARTER Editor-in-Chief Greg Migliore liveblogs the first quarter. F9 We'll count this as a car commercial. The latest edition of the Fast & Furious looks like it well, will have cars. We'll punt on further comment. PORSCHE I like it. Creative. Sort of a Night at the Museum feel. The guards stage a theft and then a car chase. The Taycan looked good. Get fired up — the future for Porsche is electric. The spot is meant to illustrate how fun that can be. I don't need any convincing.    SECOND QUARTER Associate Editor Byron Hurd is liveblogging the second quarter.  HYUNDAI Hyundai checked in super early with their Sonata "Smaht Pahk" commercial, which manages to score points for being both cute and clever while also being a fairly good commercial in a vacuum. We saw it last week, so there were no surprises here, but we enjoyed it nonetheless.  Fun note: If you go to the Sonata landing page on Hyundai's web site, you can choose "plain old English" or "the Boston way" for your language; the latter will translate the page. Enjoy.  FORD Hi ho, West Coast Editor James Riswick here. Apparently, the guys in Detroit didn't get the Mustang Mach E ad featuring Idris Elba and a whole boat load of awesome old Mustangs. Pretty sure it's bound to be viewed the exact same way as the car itself: traditionalists will be aghast, while non-car people will be intrigued by a new, all-electric, crossover version of one of the few cars they've heard of.  GENESIS They're coming more rapidly now. Genesis gets some love thanks to Chrissy Teigen and John Legend; this was another known quantity, but Hyundai's luxury brand managed another solid entry here thanks to its choice of stars. Teigen and Legend got the chance to throw back to the latter's "Sexiest Man Alive" honors, which Teigen often teases him for. Another solid all-around spot.  GMC/HUMMER Are there just no surprises left? Don't tell me; I know the answer. LeBron James fronts the revived Hummer, which will be an EV sold as a GMC.

Behold the glory of unobscured Porsche 911 Turbo bumpers

Porsche apparently sees absolutely no reason to hide the changes for the 911's upcoming refresh on any of the models. After releasing official photos of the standard version ahead of the debut, here are the Germans testing the revised 911 Turbo S at the Nurburgring with no camouflage at all. The exterior tweaks are tiny enough that maybe the company thinks no one would notice. The front bumper receives tiny adjustments, including the LED lights lengthened in the lower air intakes. The headlights are also slightly tweaked, and the taillights are the wider units from the rest of the updated range. The rear bumper receives some restyled vents at each corner, as well. The standard 911 is rumored to receive a new family of smaller displacement, turbocharged flat-six engines as soon as this year's Frankfurt Motor Show, and that leaves the Turbo in a weird place. Forced induction holds a special place in the model's lineup by denoting some of the most powerful versions. With that exclusivity possibly on the way out, Porsche might now have to find a way to keep the Turbo badge special. Related Video:

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.
