Deep Dive into the 2017 chevrolet volt specifications and Powertrain
The heart of the 2017 Volt is its second-generation Voltec propulsion system. Unlike a standard hybrid, the Volt operates primarily as an electric vehicle until the battery is depleted, at which point the gas engine takes over.
The 1.5L L3A Range Extender Engine
The internal combustion component is a 1.5L L3A range extender engine. This is an all-aluminum, naturally aspirated four-cylinder engine designed specifically for high-efficiency operation within a hybrid system.
It features direct injection and a high compression ratio of 12.5:1. This engine does not use a traditional starter motor; instead, it is cranked by one of the electric motors within the transaxle, ensuring a smooth transition during “engine-on” events.
If you are familiar with the Cruze LT specs, you might recognize the engine family, but the Volt’s version is tuned strictly for range extension and battery maintenance.
Voltec 5ET50 Multi-Mode Transaxle
The Voltec 5ET50 multi-mode transaxle is the mechanical brain of the drivetrain. It houses two electric motors and a series of planetary gears that allow the car to operate in several different modes.
- One-Motor Electric: Used during low-speed, high-torque situations.
- Two-Motor Electric: Both motors work together for highway efficiency.
- Extended Range Mode: The gas engine provides mechanical assist or generates electricity.
This unit is significantly lighter and more efficient than the first-generation version. It uses rare-earth-free magnets in one of the motors to reduce costs and environmental impact while maintaining high performance.
High-Voltage Battery and Charging System Details
The battery is the most critical component of the 2017 chevrolet volt specifications for those looking to minimize fuel costs. It is a massive, T-shaped unit located under the rear seats and center console.
The 18.4 kWh Lithium-Ion Battery Pack
The 18.4 kWh lithium-ion battery pack consists of 192 cells. It provides an EPA-rated 53 miles of pure electric range, though many drivers report getting over 60 miles in ideal weather conditions.
Maintaining the health of this pack requires a sophisticated high voltage battery thermal management system. This system uses liquid coolant to either warm the batteries in winter or cool them during fast charging and summer driving, preventing the degradation common in air-cooled hybrids.
Charging Hardware and SAE J1772 Standards
The vehicle features an SAE J1772 charging port assembly located on the driver-side front fender. This is the industry standard for Level 1 (120V) and Level 2 (240V) charging.
- Level 1 Charging: Uses a standard household outlet and takes roughly 13 hours for a full charge.
- Level 2 Charging: Requires a 240V station and drops the charge time to approximately 4.5 hours.
For DIYers, keeping the port clean and checking the 12V battery (which triggers the charging relays) is vital. A weak 12V battery is the most common cause of “Unable to Charge” errors.
Chassis, Suspension, and Braking Specifications
While the powertrain is futuristic, the chassis is grounded in solid, reliable engineering. The Volt shares some structural DNA with other GM compacts, but it is tuned for the extra weight of the battery pack.
Regenerative Braking and Friction Brakes
The Volt uses a regenerative braking system actuator to blend electric motor braking with traditional hydraulic friction brakes. When you step on the pedal, the motors first act as generators to slow the car and feed power back to the battery.
The friction brakes (discs at all four corners) only engage fully during hard stops or at very low speeds. This means the brake pads on a Volt can often last over 100,000 miles, though the slide pins should be lubricated regularly to prevent seizing from under-use.
Suspension and Handling
The front suspension uses a standard MacPherson strut design, while the rear utilizes a compound crank (torsion beam) setup. This keeps the rear compact to make room for the battery.
The curb weight is approximately 3,543 lbs, which gives the car a planted feel. The low center of gravity, thanks to the battery placement, makes it surprisingly agile for a commuter car.
Fluid Capacities and Maintenance Requirements
Proper maintenance of the 2017 chevrolet volt specifications involves managing several different fluid systems. This car has three separate cooling loops, making it more complex than a standard vehicle.
Engine Oil and Drive Unit Fluid
The 1.5L engine requires Dexos1 Gen 2 0W-20 engine oil. Because the engine may not run for weeks at a time, it is important to use high-quality synthetic oil that resists moisture buildup.
The transaxle requires DEXRON-VI electric drive unit fluid. Unlike some “lifetime” fluids, enthusiasts recommend changing this every 45,000 to 97,500 miles, depending on how much you use the range extender, to protect the planetary gears.
Coolant Systems Management
There are three cooling reservoirs under the hood: one for the engine, one for the electronics (inverter/charger), and one for the battery. All three use a 50/50 mix of Dex-Cool and deionized water.
Never top off the battery coolant with tap water, as minerals can cause electrical conductivity issues. If the battery coolant level drops below the “full” line, the car may throw a “High Voltage System” error and refuse to charge as a safety precaution.
Advanced Electronics and Control Modules
The 2017 Volt is essentially a computer on wheels. It relies on several high-level modules to manage the flow of energy between the battery, the engine, and the wheels.
Hybrid Powertrain Control Module 2 (HPCM2)
The Hybrid Powertrain Control Module 2 is the primary controller for the hybrid system. It monitors everything from cell voltage to the position of the shift lever. If you experience a “service high voltage system” message, this is usually the module that has detected a fault.
Another critical component is the Drive Motor Control Module. This unit converts the DC power from the battery into the AC power needed to spin the drive motors. It generates significant heat and is cooled by the electronics cooling loop.
For those interested in efficiency, comparing these systems to the Malibu gas mileage data shows how much more effective a dedicated PHEV platform is at energy recovery compared to a standard start-stop system.
Diagnostic Decision Flow for Common Issues
When something goes wrong with a vehicle this complex, a structured approach is necessary. Use this table to narrow down common symptoms before heading to the dealer or grabbing your scan tool.
| Symptom | Potential Cause | Recommended Action |
|---|---|---|
| “Propulsion Power Reduced” | Cold battery or low fuel | Check fuel level; allow battery to warm up. |
| Will not accept a charge | SAE J1772 port debris or 12V battery | Clean port pins; test 12V battery health. |
| Engine runs constantly | Engine Maintenance Mode (EMM) | Allow the car to finish its fuel/oil clearing cycle. |
| Check Engine Light (P0AC4) | Hybrid Module fault | Use an OBD-II scanner to read specific sub-codes. |
Always remember that the high-voltage cables are bright orange. Never touch, cut, or probe these wires unless the system has been properly de-energized by a professional. Safety must always come first when working on the 2017 chevrolet volt specifications.
