The 2022 NASCAR Next Gen transmission is a sequential manual
Though the new NASCAR Next Gen transmission is a little different than the old H-pattern manuals, it is not an automatic transmission. Drivers still have control of every single shift. But they control the transmission in a new way.
NASCAR’s new transmissions are called sequential manuals. They are similar to the ratchet shifters used in drag racing. The cars still have a floor-mounted shift lever, but it only has two positions. Drivers push the lever forward to downshift and pull it back to shift up a gear.
These new shift levers technically have a third position: drivers can pull the lever straight upwards to engage reverse. While the 2021 NASCAR transmissions only had four speeds, the new sequential manual transmissions offer five speeds.
NASCAR Next Gen cars have a clutch pedal
After NASCAR announced its new Next Gen spec, officials went into detail about the new sequential manual transmission. But no one discussed whether the new car would have two or three pedals.
Now, many automatic muscle cars feature ratchet shifter upgrades. Therefore, Nascar fans were unsure whether the sport’s new “sequential manual” was a true three-pedal car or not.
One racing fan actually put the question to Reddit’s NASCAR community. You might be surprised who chimed in with an answer.
Chase Brisco, driver of the #14 Ford Mustang frequents Reddit. Fans enjoy the insight he provides as /u/C_Briscoe. He answered “Does Nascar still have an ‘clutch pedal’ in the Next Gen Car ? (sic)” with a straightforward response: “Yes it does.”
Why did NASCAR not make a bigger deal out of the fact that the Next Gen car still has three pedals? Because the clutch pedal is not a big part of a NASCAR race. Drivers use the clutch to get the car into first. But while hurtling around the track, most drivers just match the next gear to the engine RPM and shift without a clutch.
The new NASCAR transaxle transmission is part of the rear axle
One aspect of the NASCAR Next Gen transmission affects racing much more than its shift pattern: its location. The new sequential manual transmissions is part of a Next Gen transaxle unit at the back of the car.
The NASCAR Next Gen car features a forward engine, rear transaxle layout to better balance the drivetrain’s weight. This new layout is akin to the past three generations of the Chevrolet Corvette (but not the eighth-generation rear-engine Corvette).
The new transmission does not drive a solid rear axle, but two half-shafts. These axle shafts each float on independent rear suspension, just like the stock cars the Cup car is supposed to represent.
Finally, the new transaxle leaves enough room for NASCAR’s first full length underwing. This aerodynamic feature evacuates air from beneath the car and creates 1,000 pounds more downforce. This is one of the reasons the NASCAR Next Gen cars ride higher off the ground than the Generation-6 cars.
