In some ways, but there is no question that a turbocharged engine is more highly strung and has to work harder than a normally aspirated eight cylinder engine of comparable horespower.

This could lead to shorter engine life.


There were some relatively small turbocharged engines back in 1984 (the earliest year in the EPA database). I suppose the objective in 1984 was the same as today, get higher horsepower out of an engine with better fuel economy.

It may have been to save money since a bigger engine was more expensive.

The most prevelant models to be turbocharged were domestic.

Mitsubishi, Nissan and Subaru from Japan had turbocharged models.
Renault, Saab, Volvo, Lotus, Maserati, Audi, and Mercedes-Benz from Europe had turbocharged models.

Chrysler got into it big. They had just the one 4 cylinder engine of their own so worked with what they had. It would be a few more years before Chrysler could and would make their own V-6. By the late 1980s they figured out 4 valves per cylinder got you about the same hp boost as the 1980s turbos but with far better durability and trurbos waned.

You seem to be correct. Flashing forward a decade to 1994 the EPA database shows a lot fewer small engine vehicles with turbochargers.

  1. 1.3 L, 2 cyl, Mazda RX-7
  2. 1.5 L, 4 cyl, Hyundai Scoupe
  3. 1.6 L, 4 cyl, Mercury Capri
  4. 2.0 L, 4 cyl, Eagle Talon
  5. 2.0 L, 4 cyl, Mitsubishi Eclipse
  6. 2.0 L, 4 cyl, Plymouth Laser
  7. 2.0 L, 4 cyl, Saab Convertible
  8. 2.0 L, 4 cyl, Toyota MR2
  9. 2.2 L, 5 cyl, Audi S4
  10. 2.2 L, 4 cyl, Lotus Esprit Turbo
  11. 2.2 L, 4 cyl, Subaru Legacy AWD Turbo
  12. 2.3 L, 4 cyl, Saab 9000
  13. 2.3 L, 4 cyl, Saab Convertible
  14. 2.3 L, 5 cyl, Volvo 850
  15. 2.3 L, 4 cyl, Volvo 940
  16. 2.3 L, 5 cyl, Volvo 850 Wagon
  17. 3.0 L, 6 cyl, Dodge Stealth
  18. 3.0 L, 6 cyl, Mitsubishi 3000 GT
  19. 3.0 L, 6 cyl, Nissan 300ZX
  20. 3.0 L, 6 cyl, Toyota Supra
  21. 3.5 L, 6 cyl, Mercedes-Benz S350D
  22. 6.5 L, 8 cyl, Chevrolet Blazer 1500
  23. 6.5 L, 8 cyl, Chevrolet C1500 Pickup
  24. 6.5 L, 8 cyl, Chevrolet K1500 Pickup
  25. 6.5 L, 8 cyl, GMC Sierra 1500
  26. 6.5 L, 8 cyl, GMC Yukon K1500
  27. 6.5 L, 8 cyl, Rolls-Royce Continental R
  28. 6.5 L, 8 cyl, Rolls-Royce Turbo R/Turbo Rl

In 1984 we have Dodge, Plymouth ,Ford, Mercury, Renault ,Mitsubishi, Subaru, Buick and Pontiac with vehicles with engines under 2.0 liters with turbocharging.
In 1994 we have Mazda, Hyundai and Mercury with a single model each with engines under 2.0 liters with turbocharging.
In 2022 we have Buick, Chevrolet, Fiat, Jeep, Ford, GMC, Honda, Mini Cooper, Mitsubishi , Nissan, Volkswagen, Hyundai , Kia with vehicles with engines under 2.0 liters with turbocharging.


The EPA presents the CAFE requirements as saving the consumer tons of money in lower gasoline requirements, but in fact the price of vehicles keeps soaring to incorporate these new technologies or the expansion of old technologies in new ways.
