What is Efficiency?
At its core, efficiency in an electric vehicle is measured by how many Watt-hours per mile (Wh/mile) or Watt-hours per kilometer (Wh/km) your car consumes. Think of it like miles per gallon (MPG) for gasoline cars, but in reverse: lower Wh/mile or Wh/km means better efficiency.
Wh/mile: This tells you how much energy (in Watt-hours) your Tesla uses to travel one mile.
Wh/km: Similarly, this indicates the energy consumption for one kilometer.
Why is this important? Because a lower number means you're using less energy to cover the same distance, which translates to:
More range from your battery
Lower charging costs
A more eco-friendly drive
Step 2: Accessing Efficiency Data in Your Tesla
Your Tesla is a sophisticated machine, and it provides a wealth of data right at your fingertips. The primary tool for seeing your real-time and historical efficiency is the Energy App on your vehicle's touchscreen.
Navigating to the Energy App
Tap the Car Icon: On the bottom bar of your Tesla's touchscreen, you'll see a small car icon (usually on the left). Tap this to open the main menu.
Select "Energy": Within the main menu, look for and tap the "Energy" application. It usually has a lightning bolt or battery icon.
Once you're in the Energy App, you'll see a few different sections designed to give you a comprehensive overview of your efficiency.
Real-time Driving Display
This section is your go-to for immediate feedback on your driving efficiency.
Live Energy Consumption Graph: You'll see a graph that shows your instantaneous Wh/mile or Wh/km. This graph fluctuates significantly as you drive, reflecting acceleration, braking, and changes in speed.
Projected Range: Based on your recent driving patterns and the current battery charge, the Energy App will project your remaining range. This projection dynamically updates, providing a realistic estimate.
Step 3: Analyzing Trip-Based Efficiency ️
While real-time data is useful, understanding your efficiency over a specific trip or period gives you more actionable insights. The Energy App offers dedicated sections for this.
Understanding the "Trip" and "Current Drive" Sections
Reminder: Short breaks can improve focus.
Within the Energy App, you'll typically find options like "Trip" or "Current Drive."
Current Drive: This shows the efficiency for your current, ongoing drive. It resets when you put the car in park for a prolonged period or start a new navigation.
Trip A / Trip B: Similar to traditional odometers, these allow you to track efficiency over longer, user-defined trips. You can reset these manually. This is fantastic for seeing how your commute affects efficiency or comparing efficiency on different types of journeys (e.g., highway vs. city driving).
For each trip, you'll typically see:
Average Wh/mile (or Wh/km): This is the crucial number. It's the total energy consumed divided by the total distance traveled for that specific trip.
Distance Driven: The length of the trip.
Energy Used: The total energy consumed during the trip.
Resetting Trip Meters
To get accurate data for new comparisons, remember to reset your trip meters before starting a new efficiency test. This is usually done by tapping on the trip summary and then selecting "Reset Trip."
Step 4: Delving into Historical Data and Predictions
The Energy App isn't just about the here and now; it also helps you understand your long-term efficiency trends and how different factors influence your range.
Understanding the "Consumption" Graph
This is one of the most powerful features for efficiency analysis.
Select "Consumption" Tab: In the Energy App, switch to the "Consumption" tab.
View Various Timeframes: You can typically view consumption over the last 5, 15, or 30 miles (or kilometers). This graph plots your average Wh/mile (or Wh/km) over these distances.
Compare Against Rated Range: The graph often includes a dotted line representing your Tesla's rated efficiency. This is the efficiency your car would achieve under ideal conditions (e.g., EPA rating). Comparing your actual consumption to this line helps you see if you're driving more or less efficiently than the official rating.
The "Projected Range" Graph
This graph helps you understand how your driving style and external factors are affecting your range predictions.
Actual vs. Projected: You'll see a line indicating your actual range consumption and another line showing your projected range.
Factors Affecting Prediction: The app takes into account factors like elevation changes, outside temperature, and your driving habits to provide a more accurate range estimate. This helps you understand why your battery percentage might be dropping faster or slower than expected.
Step 5: Identifying Factors Affecting Efficiency ️
Many elements influence your Tesla's efficiency. Understanding these can help you adopt better driving habits.
Driving Style is Key
Acceleration: Rapid acceleration uses a significant amount of energy. Smooth, gradual acceleration is far more efficient.
Braking: While regenerative braking helps recover some energy, hard braking is still less efficient than gentle deceleration. Anticipate stops and let off the accelerator early to maximize regen.
Speed: This is perhaps the biggest factor. Aerodynamic drag increases exponentially with speed. Driving at higher speeds (especially above 60-70 mph or 100-110 km/h) dramatically reduces efficiency.
Tire Pressure: Underinflated tires increase rolling resistance, leading to higher energy consumption. Check your tire pressure regularly!
Environmental Conditions
QuickTip: Reading regularly builds stronger recall.
Temperature: Both extremely cold and extremely hot temperatures reduce battery efficiency. Cold weather increases internal resistance in the battery and requires energy for cabin heating. Hot weather requires energy for air conditioning.
Elevation Changes: Driving uphill requires more energy, while driving downhill allows for more regenerative braking.
Wind: Strong headwind significantly increases aerodynamic drag, negatively impacting efficiency.
Vehicle Settings & Usage
HVAC Usage: Running the heater or air conditioning consumes a notable amount of energy. Use "Cabin Overheat Protection" judiciously, as it can drain your battery. Pre-conditioning your cabin while plugged in is an efficient strategy.
Sentry Mode & Summon Standby: These features, while convenient, continuously draw power, leading to "vampire drain" and reduced overall efficiency.
Accessories: Using features like seat heaters, heated steering wheel, or even phone charging consumes some energy, though usually minor compared to propulsion.
Step 6: Practical Tips for Improving Your Tesla's Efficiency
Now that you know how to see your efficiency and what impacts it, let's put that knowledge into action!
Master the "One Pedal Driving" Technique
Regenerative Braking: Tesla's powerful regenerative braking allows you to drive primarily using just the accelerator pedal. When you lift off the accelerator, the car slows down and sends energy back to the battery.
Smooth Driving: Learn to modulate the accelerator to bring the car to a stop smoothly using only regen, avoiding the need for friction brakes as much as possible. This maximizes energy recovery.

Optimize Your Speed
Highway Sweet Spot: Identify the speed at which your Tesla is most efficient. For many Teslas, this is often between 50-65 mph (80-105 km/h).
Cruise Control: Use adaptive cruise control (Traffic-Aware Cruise Control) to maintain a consistent speed, which helps avoid inefficient acceleration and deceleration.
Climate Control Strategies
Pre-Conditioning: Always pre-condition your cabin while plugged in to leverage grid power instead of battery power.
Seat Heaters over Cabin Heating: Seat heaters are generally more energy-efficient than heating the entire cabin. Use them strategically.
Defrost Sparingly: Defrosting uses a lot of energy.
Tire Maintenance
Regular Checks: Check your tire pressure at least once a month or before long trips, especially as temperatures change. Refer to your door jamb sticker for the recommended PSI.
Tire Type: Low rolling resistance tires can slightly improve efficiency.
Minimize "Vampire Drain"
Sentry Mode: If you don't need Sentry Mode in a secure location, turn it off.
Summon Standby: Disable Summon Standby if you rarely use the feature.
Frequent App Checks: Avoid constantly checking the Tesla app, as this wakes up the car and can consume a small amount of power.
Step 7: Advanced Analysis and Third-Party Tools
For the truly data-driven, there are ways to go beyond the in-car Energy App.
Exporting Data (Unofficial Methods)
Currently, Tesla does not provide an official way for owners to export detailed driving data. However, there are some third-party solutions and community-developed tools that can connect to your Tesla's API (with your credentials) to pull more granular data.
QuickTip: Highlight useful points as you read.
Third-Party Apps: Apps like Tessie, Stats for Tesla, or TeslaFi offer extensive data logging, trip analysis, historical efficiency trends, and even charging insights. These often require a subscription.
API Access: For the more tech-savvy, exploring the Tesla API can allow for custom data collection and analysis, though this requires programming knowledge and comes with inherent risks if not done carefully.
Understanding External Factors
Elevation Maps: When planning long trips, consider using tools that show elevation changes. Knowing where significant uphill climbs are can help you anticipate higher energy consumption.
Weather Forecasts: Check weather forecasts for wind conditions and extreme temperatures, as these will directly impact your efficiency.
Step 8: Interpreting Your Findings and Continuous Improvement
Seeing the numbers is just the first step. The real value comes from interpreting what they mean and using them to refine your driving habits.
Set Baselines and Goals
Establish Your Average: Over a typical week or month, note your average Wh/mile (or Wh/km). This is your baseline.
Set Improvement Goals: Can you reduce that number by 5%? 10%? Small, consistent improvements add up over time.
Experiment and Learn
Test Different Speeds: Try driving the same route at slightly different speeds and observe the efficiency difference.
Observe HVAC Impact: Note how much your Wh/mile increases when you use the heater or A/C extensively.
Long-Term Tracking: Use your Trip B meter or a third-party app to track your efficiency over several months. This will reveal long-term trends and help you see the impact of seasonal changes.
The Feedback Loop
The beauty of the Tesla's Energy App is the immediate feedback it provides. Use this feedback loop to your advantage:
Drive: Go for a drive.
Observe: Look at your real-time Wh/mile and your trip average.
Adjust: Modify your driving style based on what you observe.
Repeat: Continuously refine your technique.
