Every engine is the most efficient at max torque, which for a typical car’s gasoline engine would be around 4500 rpm.
But that “efficiency” means fuel burnt per unit of power. At max torque, the engine makes much more power than you need for normal driving, burning more fuel than necessary.
As a rule of thumb, you get the best real-world fuel economy at full throttle just above the low rpm limit where the engine would run “jerky”.
That’s at 1000-1500rpm for a passenger car’s gasoline engine.
At that rev range, you may only get 40 horsepower out of an engine rated for 100 at max torque, but that’s enough. You only need around 10 to maintain your speed against wind resistance, and you don’t actually lose any time accelerating slowly cause you’re gonna be at the next red light soon, anyway.

For reference, when I’m accelerating from a stop to highway speeds, I’ll shift to 2nd gear as soon as I’ve moved one car length, 3rd at 30km/h, 4th at 40, 5th at 50, flooring the throttle the entire time I’m not shifting. Then I’ll stay in 5th unless I’m forced to brake below ~45 again. Up or down a hill I’ll go one gear lower.
In my Diesel van, I regularly drive 40 in 5th gear.

I can’t make you take my word for it, but this is what I learned in a work-sponsored course for fuel efficient driving, and it got me much better fuel economy than the manufacturer’s claim for any car I drove in the past 20 years.

Technically, yes, there is a little automatic like shifter to let you select PRNDS (S or M for manual shift mode), but would you want to do that? nope.

My bigger q is, why are you doing a clutch kick in a supercar that will probably break if you try that? Most Lambos are 4WD, and 4WD cars will break stuff if you go for a clutch kick.

I mean, I’m still not getting an EV. But now I am tempted… Maybe if they had real, physical dials instead of a computer screen?

That, unfortunately, is the tendency for the entire auto industry. It’s not an EV-specific thing, although admittedly Tesla is the worst offender

If the 5th gen Subaru Impreza came as an EV, I would be fine with that. Two analog gauges, a digital display for the fuel, gear and mileage, and another digital lcd for the clock and range. That’s literally it on the gas car. All I need on an EV. Replace RPM with Amperage and I’d be fine.

One of my cars (the only one that isn’t a real manual) has a “sport mode” manual upshift/downshift on its automatic transmission, and it’s FUCKING INFURIATING because there’s this huge almost-a-full-second lag between when you tell it to shift and when it finally gets around to doing it.

I would trade it for a manual transmission – even in stop-and-go Atlanta rush-hour traffic! – in a heartbeat if I could.

We’re not on the same page here.

Yes, an automatic transmission with a dual clutch and paddle shifters obviously shifts much faster, has more gears, and lets you accelerate faster.
But my point is, even 200 horsepower in a sports care are already more power than you can legally use on public roads.
And stomping the clutch to the floor, then ramming a shift lever forward is simply more fun.
