Electric Cars Performance

Instant torque vs battery weight. The new era of performance metrics.

The Battery Weight Penalty

Electric vehicles (EVs) have redefined acceleration. Instant torque from 0 RPM allows even heavy family haulers to outrun sports cars to 60 mph.

The trade-off is Mass. Batteries are incredibly dense. A typical EV battery pack weighs 500-800kg alone. This affects tire wear, braking distances, and cornering inertia, even if the low Center of Gravity masks it well.

EV Ratios

  • City EV (e.g., Zoe) ~80 hp/ton
  • Long Range Sedan (e.g., Model 3) ~220 hp/ton
  • Performance EV (e.g., Plaid) ~600+ hp/ton

Efficiency vs Power

In the EV world, weight doesn't just hurt handling; it hurts Range.

Regen Braking
Heavy weight helps recover more energy during deceleration.
Instant Torque
Makes weight feel non-existent at city speeds (0-40 mph).
Tire Wear
High torque + high weight = accelerated tire consumption.
