MPG for 1972 CUTLASS SUPREME as soon as NEW= 13.0 in its entirety Average

Sorting v the reports earlier in the job reveals a labyrinth of contradictions. The many accurate numbers come from write-ups where the brand-new car"s power was measured straight in continuous use.

Motor Trend Nov 1971 experiment a Cutlass Supreme two door hardtop through the 4 barrel 350 c.i. 180 HP engine, automatic transmission and also 2.73:1 rear axle. MT observed that the Cutlass Supreme typical powertrain take it the vehicle to a optimal speed the 100 MPH. Lock didn"t have actually the automobile long sufficient to check the MPG.

The book World car 1972 compiles information detailed by manufacturers; specs are calculated rather than it was observed directly. World car 1972 lists identical peak speed and fuel mileage because that the 350 cubic customs 180 HP engine traditional in Cutlass Supremes despite two different accessible rear axle ratios listed in World dare 1972.

The Cutlass Supreme with a 180 speech 350-4 barrel is attributed with a peak speed of 116 MPH and also gas consumption of 13.0 MPG nevertheless of existence of 2.73:1 or 3.08:1 rear axle ratio. Its difficult to understand which behind axle was used by World car 1972 come calculate optimal speed. 116 MPH is much greater than the observed height speed Motor Trend achieved in your tests.

The salesperson spec overview for 1972 states that the conventional transmission and also axle because that the 350-4 barrel that was traditional in the Cutlass can be fried was the M38 automatic paired to the 2.73:1 axle. The 3.08:1 and also 3.23:1 were optional.


The figures quoted in World car 1972 for the general Motors 1972 "A body" intermediates vary wildly in spite of the cars using the exact same frames and comparable body shapes and also horsepower ratings.

World car 1972 claims that the 1972 Buick Skylark with a 180 speech 350-4 barrel, 3 speed hand-operated transmission, and 3.08:1 axle have the right to hit 103 MPH.  Pontiac didn"t have a 4 barrel 350 easily accessible in 1972. World cars 1972 credits the Pontiac LeMans v 350-2 barrel (175 hp), 3 speed hands-on trans, and 2.56:1 axle at 111 MPH. The 1972 Chevelle through a 350-4 barrel (175 hp), 3 speed hands-on transmission, and also 3.31:1 axle ratio was claimed to be able to run 112 MPH.

It seems the famed Rocket 350 Oldsmobile engine is ideal of all the engines according to World dare 1972 through 116 MPH, however it could simply be the the different division engineers estimated the ns in height speed due to compression fall using different formulas. The World cars 1972 book quotes numbers using the hands-on 3 rate transmission. The salesman"s overview shows axle ratios detailed with the manual shift 3 rate transmission and the M38 TH350 automatic as watched below.


World car 1972 receives your performance figures from the manufacturer. The gas consumption World car 1972 comes up with is based on a moderately loaded Cutlass Supreme covering variable terrain at roughly 60% of height speed, which would be about 67 MPH.



The standard 1972 Cutlass supreme 2 door convertible has actually a curb weight of 3,627 pounds follow to World dare 1972. The Oldsmobile salesman"s overview for 1972 says that the Cutlass can be fried convertible has actually a curb load of 3,614 pounds (shipping weight of 3,510 pounds).

The 3,627 pounds quoted is technically correct however unrepresentative that the bulk of Cutlass supreme 2 door convertible car built because the base auto is detailed with the lightweight 3 speed manual transmission in World dare 1972. Obviously a high end auto like this convertible doesn"t was standing pat v the standard manual transmission, but listing a stripped car is a time honored tactic used to minimize the quoted base price.

The figures below are from the AMA stat sheet giving the weight of various choices on a 1972 Pontiac. General Motors sourced their strength steering, power brakes, A/C etc from the same providers regardless of the division installing the parts. The Pontiac accessory figures use to Oldsmobile, too. The load for the radio originates from the 1967 Oldsmobile Cutlass AMA specs.

Below is a summary that the OOCC Cutlass Supreme choices and the weight increase above the base 350 4 bbl hands-on transmission "stripped" 2 door convertible:

+ 112.0 lbs- air air conditioning + 29.0 lbs- power disc brakes + 28.6 lbs- twin exhaust + 28.0 lbs- power steering + 27.8 lbs- M38 TH350 infection + 8.0 lbs- radio = 233.4 lbs added in total

A realistic complete would be about 3,880 pounds. Include 200 lbs for driver or miscelanious items and the as moved weight was about 4,080 pounds.

The traditional tires top top the Cutlass supreme convertible were F78x14 through G70x14 and also G78x14 optional. If the optional 455 was installed or if A/C was included to the 350 engine then the standard tire dimension bumped as much as G78x14.


The owner"s manual allows for a soft luxury ride through recommended light load pressures (up come 750 pounds) the 24 PSI front and also rear. Heavier lots than 750 pounds required 26 PSI front and 28 PSI rear.
