While the 2017 chevrolet volt horsepower might seem modest on paper, the instant electric torque provides a punchy, responsive driving experience that rivals many traditional sport sedans in city traffic.
In this guide, we will break down how this unique hybrid system generates its power and how you can maintain it for the long haul. We will look at the interaction between the electric motors and the gasoline engine to help you get the most out of your drive. Whether you are a new owner or a DIY mechanic, understanding this powertrain is the first step to mastering your Volt.
Understanding the 2017 chevrolet volt horsepower and Torque
The total 2017 chevrolet volt horsepower is rated at 149 hp (111 kW), but that number only tells half the story. In an electric-drive vehicle, torque is often the more significant figure for daily drivability. With 294 lb-ft of torque available from zero RPM, the Volt launches with surprising authority.
Unlike a traditional internal combustion engine that needs to “rev up” to reach its power band, the Volt’s electric motors deliver maximum thrust immediately. This makes the car feel agile when merging onto highways or darting through intersections. The power is managed by a sophisticated Hybrid powertrain control module that balances efficiency and performance.
It is important to note that the horsepower rating remains consistent whether you are running on pure electricity or using the gasoline range extender. Chevrolet engineered the system so that the driver rarely notices a performance dip when the battery reaches its minimum state of charge. This seamless transition is a hallmark of the second-generation Voltec design.
The Heart of the Voltec Multi-mode Drive System
The Voltec Multi-mode Drive System is the mechanical brain of the 2017 Volt. It consists of two electric motors and a Planetary gearset assembly. This setup allows the car to operate in several different modes depending on speed, load, and battery levels.
The primary 111 kW electric drive motor handles the majority of the propulsion duties. However, at higher speeds or under heavy loads, the second smaller motor can engage to assist. This dual-motor approach improves efficiency by allowing both motors to operate in their most effective RPM ranges.
The system also uses an Inverter power electronics module to convert DC power from the battery into AC power for the motors. If you ever experience a sudden drop in power or a “Reduced Propulsion” message, the Drive motor position sensor or the inverter itself are often the first places a technician will look during diagnostics.
Propulsion Motor Roles
- Motor A: Primarily acts as a generator but can assist in high-load propulsion scenarios.
- Motor B: The main traction motor responsible for the bulk of the 149 horsepower output.
- Synergy: By using both motors, the system reduces heat buildup and extends the life of the electronics.
The 1.5L L3A Range Extender Explained
When the battery runs low, the 1.5L L3A range extender kicks in. This is a four-cylinder gasoline engine specifically designed for the Volt’s hybrid architecture. Unlike the engine in a Cruze, this unit runs on the Atkinson cycle to prioritize fuel efficiency over raw mechanical power.
The engine’s primary job is to spin a generator to provide electricity to the motors, but in certain high-speed scenarios, it can mechanically contribute to the wheels through the planetary gears. This direct-drive capability helps maintain the 2017 chevrolet volt horsepower levels when climbing long mountain grades.
To keep this engine healthy, you should always use Dexos1 Gen 2 synthetic oil. Even if you drive mostly on electricity, the engine still requires regular maintenance. The car’s computer will occasionally run a “Maintenance Mode” to circulate fluids and prevent the fuel tank capacity from being filled with stale gasoline.
Battery Power: The 18.4 kWh Lithium-ion Pack
The source of the Volt’s electric muscle is its 18.4 kWh lithium-ion battery pack. This T-shaped battery is located under the center console and rear seats. It provides enough energy for an EPA-estimated 53 miles of pure electric range before the gas engine is needed.
The battery is thermally managed using a dedicated liquid cooling and heating circuit. Maintaining the correct coolant level is vital for preserving the battery’s ability to discharge high current, which is necessary to hit that peak 2017 chevrolet volt horsepower. If the battery gets too hot or too cold, the system will limit power to protect the cells.
Owners should be aware that the usable capacity is slightly less than the total 18.4 kWh. Chevrolet keeps a “buffer” at the top and bottom of the charge to ensure the battery lasts for the life of the vehicle. This conservative management is why many Volts still have excellent range even after 100,000 miles.
Real-World Performance: 0-60 and Driving Modes
In real-world testing, the 2017 chevrolet volt horsepower translates to a 0-60 mph time of approximately 7.5 to 8.4 seconds. While it won’t beat a Corvette, it is more than enough for confident daily driving. The car offers several driving modes to help you tailor the performance to your needs. Normal Mode is the default setting, balancing comfort and efficiency. Sport Mode reclaims the accelerator mapping to make the car feel more responsive, though it doesn’t actually increase the peak horsepower. It simply delivers the power earlier in the pedal travel for a “zippier” feel. Mountain Mode is a crucial feature for those living in hilly terrain. It reserves a portion of the battery charge specifically to assist the gas engine during steep climbs. If you are planning a trip through the Rockies, engaging this mode 20 minutes before you hit the grades ensures you have the full 149 hp available when you need it most.
Driving Mode Comparison Table
| Mode | Primary Benefit | Best Use Case |
|---|---|---|
| Normal | Maximum Efficiency | Everyday commuting and errands. |
| Sport | Enhanced Throttle Response | Merging or spirited city driving. |
| Mountain | Power Reservation | Steep inclines or heavy loads. |
| Hold | Battery Preservation | Highway cruising to save EV range for the city. |
Maintaining Your Volt for Peak Performance
To ensure you always have access to the full 2017 chevrolet volt horsepower, you must stay on top of specialized maintenance. The Volt has three separate cooling loops: one for the engine, one for the battery, and one for the power electronics. Checking these levels is a simple DIY task that can prevent thousands of dollars in repairs.
Using remote pre-conditioning is another great way to maintain performance. By warming or cooling the battery while the car is still plugged in, you reduce the strain on the electrical system. This ensures the battery is at its optimal operating temperature the moment you pull out of the driveway.
Don’t forget the 12V battery located in the trunk. Even though the big lithium pack does the heavy lifting, the 12V battery powers the computers that tell the car to start. A weak 12V battery can cause “ghost” codes and strange performance issues that might make you think there is a problem with the drive motors.
Common Troubleshooting: Power Loss and Inverter Performance
If you notice a sudden decrease in 2017 chevrolet volt horsepower or the car feels sluggish, you should check for diagnostic trouble codes (DTCs). One common issue involves the P0A78 drive motor inverter performance code. This usually indicates a communication or hardware fault within the power electronics.
Another potential failure point is the Drive motor position sensor. If this sensor fails, the computer won’t know the exact orientation of the motor’s rotor, leading to jerky acceleration or a complete “no-go” condition. These high-voltage components should generally be handled by a certified technician, but a DIYer can use an OBD-II scanner to identify the fault.
Always check the air filter for the 1.5L engine as well. While it doesn’t run all the time, a clogged filter will force the engine to work harder to generate electricity, which can lead to increased noise and vibration. Keeping the mechanical side of the car clean ensures the transition between gas and electric remains seamless.
Symptom-to-Cause Troubleshooting Matrix
- Symptom: Reduced Propulsion message on dash. Likely Cause: Low battery buffer or cooling system fault.
- Symptom: Jerky acceleration at low speeds. Likely Cause: Drive motor position sensor calibration issue.
- Symptom: Gas engine running loudly/constantly. Likely Cause: Battery state of charge is too low or Mountain Mode is active.
- Symptom: Loss of electric range in winter. Likely Cause: Heavy use of cabin heater; normal battery chemistry behavior.
Frequently Asked Questions About 2017 chevrolet volt horsepower
Does the gas engine increase the total horsepower when it’s running?
No, the total system output remains capped at 149 horsepower. The gas engine primarily serves as a generator to keep the electric motors running. While it can mechanically assist the wheels at high speeds, it does so to improve efficiency, not to add to the peak power rating.
Why does my Volt feel faster than other cars with 150 horsepower?
This is due to the 294 lb-ft of instant torque. Electric motors don’t have a “torque curve” like gas engines; they provide maximum twisting force the moment they start spinning. This creates a sensation of rapid acceleration that gas-powered cars usually require much more horsepower to achieve.
Will using Premium gas increase my horsepower?
Unlike the first-generation Volt, the 2017 model is designed to run on 87-octane regular unleaded gasoline. Using premium fuel will not increase the 2017 chevrolet volt horsepower or significantly improve your fuel economy. Save your money and stick to the manufacturer’s recommendation.
