That race is the one I really want to see. My guess is the Tesla gets the jump off the line, neck and neck to about 45 mph, and then adios Tesla. I don't think any street car can be the P85D in the first 40 to 50 feet. 864 pound feet of torque at zero rpm electronically distributed to 4 wheels is pretty hard to beat off the line.

Again, the Tesla is an excellent comfortable one pedal use car, but why this huge power, the range at 155 mph is ~36 miles.

Calculation Tesla website: (P85D, Highway, 70°, Dual Motor AWD) at 70 mph ---> 261 miles range

Curb weight: 2180 kg
cw: 0,24
A: 2,34 m²
cr: 0,010
rho: 1,2041 kg/m³
g: 9,81 m/s2
P = cw * A * rho/2 * v³ + cr * m * g * v / all by 0,8 (Efficiency battery & drive train 80%)
---> Model S power required at 75 mph 25 kW

Required power at 155 mph ??
P=131 KW - Efficiency 80% ---> Model S power required at 155 mph 164 KW
Range at 75 mph with 25 kW ~241 miles ---> X/241 = 25/164 ---> X=36
Range at 155 mph with 164 kW ~36 miles

The P85D has the power for 155 mph, but can not really use it.

Great analysis. This is why a hybrid system is likely the best performance solution, with An electric motor torque-filling where an ICE is deficient.

 

No.

That's the old hybrid idea; why to provide the capabilities for high acceleration, why carrying a big engine all around with all the negative aspects:
- weight of a big block engine
- lots of internal friction caused by 8 or 12 cylinder engine ---> high fuel consumption
why for one or two times a day fast acceleration?

Why not using a small 4 cylinder engine with 164 KW / ~230 hp for desired top speed (e.g. 155mph) and additional an electric torque-filling motor (hybrid car) for sometimes high acceleration?

E.g. ... VW Golf GTE Hybrid vs VW Golf GTI
145 hp + 102 ehp = 198hp vs .. 210 hp max. power
145 hp ......................... vs .. 210 hp average power
1600 kg curb weight ....... vs .. 1400 curb weight
39 mpg gas ................... vs .. 27 mpg gas
37.000$ ........................ vs .. 27.000$
National Average Price Between October 2014: Gasoline $3.34/gallon ---> car price difference 10.000$ ~3.000 gallons.
The gasoline consumption difference of 12 mpg compensated by car price difference ---> ~239.000 miles drive for tie.
That's exactly the way to the moon. Reaching the moon means, now both cars are price equal.

E.g. Mercedes S400 Hybrid vs. S350 BlueTec ---> ~same

Cons for hybrid customers
- Higher price
- Higher curb weight
- Lower average power and performance, because total system power only available, When its batteries are charged
- More technology build in, more complex systems, more parts can fail, reliability comes down
- Lower lap times
- The life time total energy use is in best-case scenario equal, but probably worse rather than better


3 Days ago, my colleague drove with his 115 hp e-Golf 55 miles (-3° deg, 80% german Autobahn, constant speed 65 mph).
VW predicted 100 miles range. He felt slightly cold, because he did not dare to heat the cabin as pleasant.
He reached his destination with +5 miles remaining range and was slightly affected through range anxiety.

Instead of his 35.000 Euro e-Golf, he could have bought a Golf TSI Sportline with 120 hp, 7-speed-auto, hot cabin, constant speed 110 mph, 400 miles remaining range, for 26.000 Euro, or a BMW 3series 318d, 140 hp, 8-speed-auto, hot cabin, constant speed 120 mph, 600 miles remaining range, for also 35.000 Euro.

 

That's what I meant. Would need to find the ideal power to weight ratio/mix of electric and ICE for optimal performance.

 

I couldn't really find one.
The problem remains, the electric motor has to be integrated into the power train. Additional are the power electronics unit, the voltage converter, the high-voltage battery and computer management for controling the electric motor on demand.

E.g. compare the Toyota Prius with ohter cars, you may get much better comfortable and performance cars for same price and with not much higher fuel consumption.
