Performance & Mileage

Big displacement means lots of torque, but it also hurts fuel economy. Expect 10‑15 mpg in city driving for the older iron‑block giants, while the newer supercharged LS9 can manage around 12‑14 mpg combined. The modern 6.4 L Hemi is a bit kinder, delivering roughly 15‑17 mpg on the highway.

Price & Rivals

When these engines were new, they commanded premium prices. The 8.0 L Cadillac cost over $15,000 in 1994, while a brand‑new C6 Corvette ZR1 with the LS9 sold for about $100,000. Today, a well‑maintained 426 Hemi muscle car can fetch $30‑40 k at auction, competing with modern V8s that rely on forced induction rather than sheer size.

FAQ

• What is the fuel economy of the biggest V8s? Most large‑displacement V8s achieve 10‑15 mpg city and 13‑17 mpg highway, with modern models like the 6.4 L Hemi being the most efficient.
• Are any of these engines still in production? Only the 6.4 L Hemi and the 5.3 L Jaguar V8 are still made today; the rest are legacy designs.
• Is buying a car with a huge V8 worth it? If you love torque, sound, and the heritage of big‑block muscle, the experience outweighs the lower fuel economy and higher maintenance costs.
