Fuel economy at a glance
These are the EPA's official ratings for the 2005 Spyker C8 Spyder Wide Body. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 15 MPG |
| City MPG | 13 MPG |
| Highway MPG | 18 MPG |
| Annual fuel cost | $4,000 |
| Tailpipe CO₂ | 592 g/mi |
| Fuel type | Regular |
How the 2005 Spyker C8 Spyder Wide Body compares
The 2005 Spyker C8 Spyder Wide Body returns 15 combined MPG. Cars in the Two Seaters class for the same model year average 17.6 MPG, which puts this car behind the class average by about 15%.
The most efficient car in the Two Seaters class for the 2005 model year is the Honda Insight at 47 MPG. The bar chart below puts the Spyker C8 Spyder Wide Body alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2005 model year (across all classes) returns 18.5 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2005 model year is on its own page.
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 1000 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $2,000 |
| Average driver, 15,000 miles per year | $4,000 |
| Heavy driver, 25,000 miles per year | $6,667 |

Specifications
The 2005 Spyker C8 Spyder Wide Body runs a 4.2-liter 8-cylinder engine paired with a manual 6-spd, sending power through rear-wheel drive.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
