What are the typical causes of reduced fuel efficiency in a 2015 Chevrolet Corvette Z06 during city driving?

Poor Driving Habits and Conditions

• Frequent stop-and-go driving, which does not allow the car to maintain an efficient speed.
• Rapid acceleration and harsh braking, which both increase fuel consumption.
• Short trips that do not allow the engine to reach optimal operating temperature.
• Idling for extended periods, which burns fuel without moving the vehicle.

Improper Tire Pressure

• Under-inflated tires create more rolling resistance, increasing fuel consumption. Regularly check and maintain tire pressure according to the manufacturer’s recommendations.

Weight and Cargo

• Excess weight from carrying heavy loads or additional cargo can decrease fuel efficiency. Remove unnecessary items from the car to reduce weight.

Poor Vehicle Maintenance

• Dirty air filters reduce air flow to the engine, making it work harder and consume more fuel.
• Old spark plugs can cause incomplete combustion, wasting fuel.
• Using the wrong type of motor oil can affect engine performance and fuel efficiency. Always use the recommended oil type and grade.

Aerodynamics

• Having windows down or a sunroof open at city speeds can increase drag and reduce fuel efficiency.

Fuel Quality

• Using lower octane fuel than recommended can affect engine performance and fuel economy.

Driving Environment

• City driving often involves traffic congestion, stoplights, and frequent stops, all of which can contribute to reduced fuel efficiency.
