Why aren’t car acceleration getting faster?

I understand some countries have max speed limit for cars. But why aren’t more sport cars have sub 2 seconds 0-60 acceleration? Do we just don’t have the technology?

      This just says we need more force which is basically what he is asking—why don’t we have it

      More force —> more traction —> more weight

      The theoretical limit with current tires is around 2.4 seconds

    Coefficient of friction between Tyre and road is perhaps the second most important factor after driver skill and passenger comfort. If it accelerates too fast it will just skid, so you need the right rubber and mass/down force of the car, which is probably why the Tesla doesn't allow you to do it although it quite possibly can.

    They're called AWD electric cars

    Lots of good but partial answers here, but I’ll take a stab. Talking about consumer vehicles, first factor is generally power. AWD helps but 100hp/ft*lb is marginally worse than 1000/1000 but fwd. Major power in consumer vehicles factors are price, reliability, technology. As others say BMF in electric motors means the torque efficiency starts at 100% then goes down which means their upside is higher than gas but there economies of scale aren’t there yet. Tag @nio guys to see powerful cars with high price points. Traction is a factor, FWD<RWD<AWD, generally speaking. Factored in there is the trans, drivetrain (diffe, torque vector, launch control). Like power train these cost money in consumer vehicles. Someone mentioned skill which is becoming more of a factor as Tesla Model S ludicrous mode is putting drag acceleration in goofball hands. When we track our big boys (ZR-1, Z06, Z-28 etc) you have to have multiple certifications to drive because the recent 0-60 speeds are beyond most skill sets.

    I’m guessing your context is why aren’t there more tesla roadster 2’s? Tire rubber just isn’t grippy enough and gasoline engines can’t modulate power finely enough. How do you make a car accelerate without burning rubber? Comes down to what happens between road and tire, not power. These 2.3 second cars are approaching the limit, especially with the properties of gasoline engines. Look at 60-100mph speeds to understand how much power a car puts out rather than 0-60.

    Have to prevent regular people from it, most can barely drive as it is.

    Tire compounds is the reason. Drag cars with wrinkle slicks have been throwing down great 60 foot times for decades. Power is easy, putting it down is hard.
