How can I improve my Tesla's efficiency?

What hurts Tesla efficiency

Wh/mi (or Wh/km) gets worse from a combination of driving style and environmental conditions. The most influential factors are:

• High speed — drag rises with the square of speed, so 75 mph is over 20% less efficient than 60 mph
• Hard accel and decel — energy lost to heat during acceleration is hard to claw back
• Cold ambient temperature — battery output drops and cabin heating draws extra power; winter typically loses 20–40%
• Underinflated tires — being 7 psi (0.5 bar) low can cost 5%+
• Always-on features — Sentry Mode, Cabin Overheat Protection, polling from third-party apps

5 practical ways to improve Tesla efficiency

1. Maximize regen braking

Lifting off the accelerator alone produces strong regen on a Tesla. Pressing the brake pedal blends in friction braking, where energy is dumped as heat. Switching to "keep distance, lift early" driving alone tends to improve city efficiency by 5–10%.

2. Cruise at 50–62 mph (80–100 km/h)

Tesla efficiency peaks in the 50–62 mph (80–100 km/h) band. Above 75 mph (120 km/h), drag spikes and you lose 20–30% efficiency. On highways, let cruise control hold a steady speed.

3. Check tire pressure monthly

Being even 7 psi (0.5 bar) below Tesla's recommended pressure (printed on the driver's-side door jamb) can cost 5%+ in efficiency. Check monthly, and consider running closer to the upper end of the spec as temperatures drop in fall and winter.

4. Precondition 15 minutes before departure

Warming the cabin and battery just before driving slashes in-trip HVAC load. Use the Tesla app or Scheduled Departure to start preconditioning ~15 minutes before you leave — this is especially powerful for winter mornings. A warmed pack also restores full regen strength.

5. Use Sentry Mode strategically

Sentry Mode can consume 1–3 kWh per day while parked. Instead of leaving it always-on, use the "Exclude Home, enable in public" approach to keep monthly draw under control. Tesla's "Excluded Locations" setting on the vehicle handles this for you.

Different tactics for winter and summer

Winter (below 32°F / 0°C)

• Always precondition before driving
• Lower cruise speed slightly (55–62 mph / 90–100 km/h)
• Use seat heaters to reduce HVAC heating load
• Run cabin heating while still plugged in to charge

Summer (above 86°F / 30°C)

• Reconsider Cabin Overheat Protection ("Fan Only" is much gentler on the battery)
• Park out of direct sunlight
• Turn Sentry Mode off for long parking sessions
