I'm amazed how fast even basic cars are today compared with muscle cars of 1970.

Mini-vans can book it!  Put one of those engines in a little Miada or something, and I bet you're in Stingray territory.

Man, I’m starting to have frame issues at full thrust myself....
Have you tried stretching first?

Just take a basic Honda Civic or Accord and compare 0-60 times with "muscle cars" of yore.  They compare pretty well overall.  The top Honda Civic would smoke nearly any muscle car.

So would the top Golf (which has AWD which really helps).

There was a period from about 1974 to 1984 when even the fastest cars were really slow, a 0-60 time under 10 seconds was "fast".  That was the nadir for performance for cars.

The key factor is torque and horsepower, or if you will power to weight ratios.  They are MUCH higher today, and yes, tires offer more traction, especially the summer tires.  Probably the best single thing to make your own car handle better is to add summer - and then winter - tires, in place of all seasons.

My 1973 Chevy Nova with a 5.7 L engine had 185 horsepower, which is trivial by today's standards.   A base Honda Accord has 192 (from 1.5 L turbocharged, up to 252 in higher trims).

And of course modern engines usually add fuel injection and excellent breathing and computer controls that mine lacked.  That Nova was considered to be a pretty fast car in its day, and it got 18 mpg on the freeway even at 55 mph.

as you know, everything changed with new regulations in 1973

my 1970 Nova SS had the 300hp 350/5.7

yes, I could get close to 20 mpg and that was with 411 gears in the 12 bolt rear end, about 3,000 rpm at 60 mph

That 300 horsepower was gross, my 185 horsepower was SAE net, a very different figure, about the same as 285 gross.

The air pump took away about 10 horsepower and some fuel economy.

1967 Chevrolet Camaro SSCompare Car0-60 mph 7.9 | Quarter mile 15.2
1969 Chevrolet Camaro ZL-1Compare Car0-60 mph 5.2 | Quarter mile 11.6
1972 Chevrolet Camaro GTCompare Car0-60 mph 10.4 | Quarter mile 17.4
1972 Chevrolet Camaro Luxury GTCompare Car0-60 mph 9.7 | Quarter mile 17.0
1972 Chevrolet Camaro Z28Compare Car0-60 mph 7.4 | Quarter mile 15.3
1974 Chevrolet Camaro Z28Compare Car0-60 mph 8.0 | Quarter mile 15.2
1975 Chevrolet Camaro (350ci)Compare Car0-60 mph 10.9 | Quarter mile 17.2

Aside from that ZL-1, those are pedestrian acceleration times by modern metrics.  And the ZL-1 would not be considered truly exceptional today, just fast.  A VW Golf R would be faster.

If you're saying that charging his EV is more expensive than an equivalent refill at the gas station (say 4 gallons for 30 mpg vehicle = 120 miles, which is probably ~$10 if gas is $2.50 / gal, which would be lower than usual) that's surprising. I just looked this up so I could be wrong, but supposedly the Model S has a 100 kWh battery capacity, which at $0.10 / kWh (which is more expensive than in most states except AK, HI, CA, NY, and New England) would also cost $10 to charge....... Maintenance costs for EVs should also be lower (no oil changes, fewer parts that could break, etc.).

Unless your friend is an unusual electricity rate structure (most residential customers have simple flat rates, though ComEd is one of the few utilities that offers real-time pricing to residential customers, which should actually help them save money as I did when I lived in Chicago - especially for him if he were charging his vehicle at night.... IL is also deregulated so he could've gotten a bad deal from a retail energy supplier if he signed up with one) I don't understand why that would happen....
Nah. That's not what I wrote.

If you buy an EV and charge the battery routinely, you'd expect to see your bill rise, but not nearly as much as you save not buying gasoline and brakes and whatnot.

I'm not sure why all cars don't use regen braking now in place of an alternator.

What do y'all need winter tires for?
