Introducing A More Efficient Corvette.

That’s it on the right, the 1975 Corvette.

It has something no Corvette has ever had before: the Chevrolet Efficiency System.

 Efficiency System?

We’re talking about a series of significant engineering improvements working together for the very first time to help lower the cost of operating your Corvette while, at the same time, improving engine performance.  No small accomplishment.

System components include High Energy Ignition, catalytic converter, Early Fuel Evaporation, outside air carburetion and steel belted radial ply tires.

High Energy Ignition

With High Energy Ignition, there is no breaker point, there is no ignition condenser.

More important, the solid-state circuitry, plus a special High Energy Ignition coil, provides a hotter spark than conventional ignition systems do. 

Catalytic converter.

As you probably know, a catalytic converter is part of the exhaust system on every 1975 Corvette.

Essentially, it involves a core of porous pellets coated with platinum and palladium which helps complete the oxidation of carbon monoxides and hydrocarbons.

Using unleaded gas, the 1975 Corvette should emit the cleanest exhaust of any Corvette ever.

And with the converter on the job, the factory can now tune your Corvette more toward smooth, responsive, efficient performance.

Early Fuel Evaporation.

Early Fuel Evaporation is designed to reduce the possibility of chugging and stalling when you first start out.

EFE uses exhaust gases in a more sophisticated way to warm the incoming fuel-air mixture so you can be on your way sooner, and more smoothly.

With EFE, the automatic choke cuts out faster, which should help save you gas on short runs in cold weather.

Outside air carburetion.

Air trapped under the hood of a running automobile is hot stuff.  Outside air is cooler and denser.

We have found that, after warm-up, the use of a carburetor induction system that puts outside air in the fuel-air mix contributes to improved performance.

The roll of radials.

Corvette’s Efficiency System extends right to the road and those special GR70-15 steel-belted radial ply tires.

Above and beyond the handling and durability characteristics offered by steel-belted radials, they roll with less resistance

Extended service intervals.

The 1975 Corvette will also go longer between recommended oil changes, oil filter changes, and transmission fluid changes.

Example:  we now recommend oil change and chassis lube every six months or 7,500 miles.  Last year it was four months or 6,000 miles.
