2023 Grand National Roadster Show Mega Photo Gallery | Hot rod heaven

POMONA, Calif. — From an outsider's perspective, it would be easy to assume that the Grand National Roadster Show has always been a Southern California institution. After all, it celebrates the diverse postwar car culture of the region — hot rods, lead sleds, lowriders, and more. However, the show had its roots in NorCal in 1950 when Al Slonaker and his hot rod club showed their custom cars at the Oakland Expo. The GNRS moved to Pomona, California, in 2004. By then it had grown exponentially and seen about a dozen more car customization trends come and go. However, the show and its centerpiece award, the America's Most Beautiful Roadster prize, celebrate what is perhaps the first of those trends: the American hot rod in its purest form. Today, in its 73rd year, the GNRS is the oldest indoor car show in America. Annually it welcomes 500-800 cars, gathered into special themes like Tri-Five Chevys or Volkswagen Bugs. At this year's show, which was last weekend, a special hall was dedicated to pickup trucks built between 1948-98, including mini-trucks, groovy camper bed conversions, and resto-mods.  However, of all the vehicles presented, only nine are eligible for the America's Most Beautiful Roadster award. Winners get their names engraved on a 9-foot-tall perpetual trophy that was, according to The Ultimate Hot Rod Dictionary, the largest in the world when it debuted in 1950. Slonaker chose the word "roadster" initially because "hot rod" bore slightly negative outlaw connotations in 1950. Only American cars built before 1937 of certain body styles — roadsters, roadster pickups, phaetons, touring cars — are eligible, and they cannot have roll-down side windows.  Cars in the running for the cup cannot have been shown anywhere else before their debut at the GNRS.  Contestants for this accolade essentially build their cars to the a platonic ideal of a hot rod. This year the honors went to Jack Chisenhall of San Antonio, Texas, for his "Champ Deuce," a 1932 Ford Roadster. It's exactly what you picture when you think of a hot rod, but distilled to its absolute essence.  Other standouts included "Green Eyes," a two-tone green 1959 Chevy El Camino  with a heavily metal-flaked bed, "Blue Monday," a 1964 Buick Riviera lowrider, and a personal favorite, "Purple Reign," a purple and black 1951 Mercury. Cars may have started out as tools, but there aren't shows like this filled with custom refrigerators.

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 Chevrolet C7 Corvette wastes no time zooming into Jay Leno's Garage

Where else would you expect the 2014 Chevrolet Corvette Stingray to show up first? Although this time it isn't exactly in Jay Leno's Garage, Leno instead playing an away game at Brown's Classic Auto in Scottsdale, Arizona. Nor does Leno drive the car, instead taking an 11-minute walkaround of the new American sports car with General Motors design head Ed Welburn, the same man who recently brought by a string of classic Corvettes to the talk show host's California compound.
It is, admittedly, a love-fest for the American sports car now featuring 450 horsepower and 450 pound-feet of torque, but one that also features admissions about previous Corvette seats like "they were kinda rough," and the explanation that labeling the coupe "Stingray" means not having to call it "the base Corvette." On top of that, Welburn also explains the proper application of the term "dashboard." You can watch it all in the video below.
