![]() All this conspires to reduce the acceleration before the end of the pass arrives and the parachutes come out. Imagine travelling along a freeway at 100kmh, then one second later hitting 260kmh!Īs the speed increases, so does the downforce and the drag on the car, while the tyres have also grown, effectively making the gearing taller. For about one second (1.5 seconds after beginning the run) the dragster is pouring on over 100mph (160kmh) for each second of time. But for us the most amazing thing to remember is the Top Fuel dragster is already moving at around 150mph (a touch over 240kmh) before it reaches peak acceleration. Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539.1 km/h) and finishing the 1,000 foot (304.8 m) runs. A Bugatti Veyron might hit 1.5G under full acceleration in low gear. Two Top Fuel dragsters side by side during an NHRA event in 2012. 2 a second before the car will ‘roll out’ and start the track timing system).įor comparison, a space shuttle pulls about 3G as it launches into orbit. Acceleration can now increase without the risk of overpowering the track.Īfter that low point of acceleration at about 1.3 seconds into the run, a second later the Rapisarda Top Fuel dragster was pulling a peak of 5.42G at 2.3 seconds into the run, about where the car is passing the 330 foot beams (remembering that the data starts about. The dragster has increased in speed and downforce from the massive rear wing is now pushing the car down on to the track surface, allowing the tuner to further lock up the clutch and unleash more nitro horsepower. ![]() After that the magic happens (you can click the image above to see the full res version). What follows is kinda interesting! After about half a second the acceleration tapers off, down to just over 3G after about a second of acceleration. It doesn’t take long for the car to reach 4G, in fact it’s shortly after it leaves the staging beams – within a quarter of a second of the driver hitting the loud pedal. We got in touch with Rapisarda Autosport International’s Santo Rapisarda Jnr and asked if he would send through a g-force reading from one of his runs – he flicked us through their personal best 1000 foot pass from Pomona, a 3.76 at 322mph. ![]() I very much believe that in this new pursuit, many enthusiasts will meet an unfortunate demise from injury.Top Fuel dragsters are well known as the fastest accelerating race cars on the planet, but where do they actually accelerate the hardest? The answer may surprise you. The unfortunate side of this is that we have learned much from combustion motors and have in-turn learned to respect them and make improvements while being reasonably safe. The torque is instantaneous, so we will hit a point where we will need to intentionally slow down the tech so that organs do not experience fatal trauma from sheer G-forces. As battery cell efficiency gets better, so will the output potential.Ĭonsider that an electric rail gun can not only propel a bowling ball projectile so fast that it turns it into a state of plasma, but it can easily launch a refrigerator as if it were a bullet leaving a gun. We maximize this with forced induction or other methods.Įlectric potential of stored electrons is extremely efficient, but we face limits of current technology's rate of discharge versus size. With combustion, we convert heat into kinetic energy, and the efficiency of that conversion by the motor is what determines its power output per displacement.
