Iāve been told that the DE has the rear motor of the GT in both front and back. The GT has a different motor for the front, somewhat less powerful. I am not a power electronics or motors guy, so thatās as far as my knowledge goes there at the moment.
Just for fun- pulling this thread we can speculate. This is likely to prove wrong in time, but itās interesting anyway. A 1070 hp Gravity with two identical motors would work out to 535 hp each. Given that the GT makes 828 that suggests the front GT motor makes 293 hp, giving the GT a 35.4% front/ 64.6% rear power split. Of course without knowing the gearing we can only speculate what the
torque split is, and thatās the important number for traction.
Next: the Gravityās GTās 3.4 second 0-60 sprint requires a constant acceleration of roughly 0.8 Gs. If we assume a 50/50 weight distribution and a CG height of 550mm (just a guess, 30mm less than that reported for the Model X which is itself speculation) the 0.8 Gs of acceleration would transfer 14.5% of vehicle mass to the rear, making an ideal torque split for equal traction at all four corners 35.5% front, 64.5% rear. The fact that this is virtually identical to the power split listed above seems more than coincidental.
Weights have not been released, but in order to achieve 0.8 Gs of acceleration a 5750 lb Gravity (with driver) would need a constant 4600 lbs of combined thrust at the contact patch. With equal front to rear gearing we can estimate this as 1628 lbs of forward thrust coming from the front axle and another 2972 lbs at the rear.
For comparison the Lucid Air Sapphire hits 60 in 1.9 seconds, requiring a constant acceleration of a ridiculous 1.44 Gs (likely less than this due to roll-out, but close) and, at an assumed 5400 lbs with driver, a combined 7776 lbs of forward thrust at all four wheels. It also proves that Lucid is able to put 1.44 Gs worth of thrust to the ground.
If Lucid has in fact used the same rear motor with the same gear ratio in the front of the Gravity it will likely put roughly equal thrust to the ground due to similar diameter front tires (assumed pending specs). Thus the combined thrust of the Dream would be 2972 lbs at the rear and another 2972 lbs at the front for a total of 5944 lbs. Assuming a slightly heavier 5850 lb weight with driver (mostly options, not the motor weight) this will result in a potential acceleration of 1.02 Gs. This would transfer 18.5% of the weight from the front to the rear axle using the assumptions above, resulting in 1843 lbs on the front axle. 2972 lbs of of forward thrust with just 1873 lbs over the axle would be the equivalent of 1.61 Gs, so more thrust to weight than the Sapphire- I suspect the car couldnāt put the full down, and will either be traction control limited or geared differently at the front.
If we re-calculate acceleration based on what thrust the front wheels can likely sustain we get thrust in the 2750 to 2800 lb range for the front axle resulting in roughly 5750 lbs thrust total, for a potential sustained acceleration of .98 Gs. This equates to a 0-60 time of 2.8 seconds in ideal conditions. In a perfect world Lucid would re-gear the front motor slightly to reduce peak torque to the wheels but hold it longer, resulting in the same 0-60 but slightly better mid-range.
Soā¦ 2.8 seconds to 60 is my guess for the Gravity Dream. Thatās a bigger gap to the GT than Iād expected if Iām honest.
I called my SA and asked him to swap it. Took zero effort from my part, cost me nothing extra, and I got an order modification email.
