Handling: There is no way the Tesla will handle similarly to a Porsche. Steering feel, cornering, road feel. Porsche is the king of handling for a reason, and I'm anxious to see what they can accomplish with the low CG of an electric vehicle.
Consistency: The Porsche can keep doing pulls from 100% down to 10% charge consistently with no performance degradation. This was actually Porsche's main focus, an actual electric track car.
Fit and Finish: Again, anybody who's seen both a Porsche and a Tesla up close will know it's not even a competition.
Charge Time: The Porsche will charge twice as fast as a Tesla, which (assuming you can find a fast enough charger) is pretty cool for quick recharges.
I'll admit that the Taycan will be very nice looking, but it will also be about twice the price, if going for the same performance.
>> price is not that ridiculous
This seems like an insanely unlikely combination.
So where the Taycan as a range places within that is quite relevant. All the signs at the moment are that it will price similar to the 911 ie probably starting at £65-70kish. But we only have one data point which is the £130k for the Turbo trim level.
