Understand the Gen 7 cars will have a transaxle that the teams will not be allowed to service or modify or change the gearing. I doubt the gearing for Bristol and Talladega will be compatible with gearing for the Roval or Watkins Glen. Understand transaxle turnaround is two weeks or more. Yep they are really going to save the little guy money with the Gen 7 cars. They're getting an extra cog in the gearbox presumably to cover that problem, question is will 5 ratios be enough? NFW

So 1st & 2nd will cover Bristol and Martinsville 3rd for the 1 mile ovals - Dover, Richmond etc. 4th for the mile and a halves 5th for Daytona & Talladega Yep - that the ticket!

I’m thinking NASCAR will be changing the gear ratios track to track and sealing the gear boxes. They’ve mandated gear ratios for 6 years now.

I read somewhere - there is a minimum two week turn around in sending the transaxles back to the manufacturer for gear changes and sealing. How many transaxles will a team need to own? At what cost? The 'talk' is that NASCAR wants a single Gen 7 car to be able to run at all variety of tracks - bull rings, miles, 1.5 milers, Superspeedways and Road courses. Ha Ha Ha Ha

Single supplier part sourcing is not the way to cheaper racing.

Hmmmm, the cars themselves will (hopefully) cost the same as a car today, but each team would need less inventory as the chassis/bodies wouldn't be built for a specific type of track.
Done correctly, they could eliminate pack racing at Dega and Daytona. Please Lord, help them solve pack racing.

Only thing that stops pack racing is where the car has more power than tires and aero thus separating drivers from 'dim bulbs' that rely on tires and aero to keep up with the DRIVERS.

"When downforce dominates power so that a car can be driven flat-out without lifting around a high-banked superspeedway it results in ‘pack racing’." SourceOr in NASCAR's case it's caused by restrictor plates/tapered spacers. "The drawback to the use of the restrictor plates has been the increased size of packs of cars caused by the decreased power coupled with the drag the vehicles naturally produce. At Daytona and Talladega, most races are marred by at least one wreck, usually referred to as "the Big One", as cars rarely become separated." SourceFans who have never driven a stock car at speed complain that it's "too easy". "It needs to be harder." If that were the case there would be no accidents. We all know there are too many accidents slowing the race. Too many cars getting torn up.

Permit side contact and 'bump drafting' into the corners and you are sanctioning everybody that can, to perform a Police inspired PIT maneuver. Many are good as hitters - not so many are good hitee's and still able to control their cars.

I’m thinking NASCAR will be changing the gear ratios track to track and sealing the gear boxes. They’ve mandated gear ratios for 6 years now. I wonder why they don't go to a really simple solution ... the 'quick change' final drive like is in use at so many short tracks all over the country? That way only the final drive ratio is affected.

Much too simple of a solution.

They're going with a rear-mounted 6-speed sequential transaxle. So, the rear will have independent suspension will coil-over dampers.

I want to say I heard they were running spec gear ratios for each track. But I can't find that anywhere...

We have completed the NASCAR 'Regular Season'.
From my vantage point - the G7 car is too strong in the fenders and rear clip. The impact forces from walls and other cars are not be absorbed by body deformation and those forces are being sent directly to the driver. The safety aspects of cars depend upon the car crumpling and absorbing the impact forces thus extending the time for deceleration of the drivers seat during an incident.
With the bodywork being composite (carbon fiber & Kevlar?) it is not deforming in the same manner as former all steel cars and is thus transmitting more crash force straight to the drivers seat.

They haven't yet solved the problem with the number one risk to the driver.
Fire and bi-products (toxic smoke). In the Kevin Harvick incident, fire seems to have a clear path from the fuel cell area ("trunk") into the driver's compartment. Yes most things are learned by racing, but that's a problem that's been solved for at least 40 years...
The removable/replaceable front clip is too stiff as well.
The racing itself is better IMO (unless you're a Ford guy). Those spec engines Ford was against using? Yeah...

I didn't see the fire coming from the fuel cell area, however, the fire and its byproducts seemed to be entering the cockpit from the right side of the dash.
