MPG because that 1972 CUTLASS SUPREME once NEW= 13.0 as whole Average

Sorting with the reports earlier in the work reveals a labyrinth the contradictions. The many accurate numbers come from articles where the new car"s performance was measured directly in consistent use.

Motor Trend Nov 1971 experiment a Cutlass Supreme 2 door hardtop with the 4 barrel 350 c.i. 180 HP engine, automatic transmission and also 2.73:1 rear axle. MT observed the the Cutlass Supreme typical powertrain take it the car to a height speed of 100 MPH. Castle didn"t have the car long sufficient to test the MPG.

The publication World cars 1972 compiles information detailed by manufacturers; specs room calculated rather than it was observed directly. World dare 1972 lists identical height speed and fuel mileage because that the 350 cubic customs 180 HP engine typical in Cutlass Supremes in spite of two different available rear axle ratios provided in World dare 1972.

The Cutlass Supreme with a 180 horsepower 350-4 barrel is attributed with a optimal speed of 116 MPH and also gas consumption of 13.0 MPG regardless of visibility of 2.73:1 or 3.08:1 rear axle ratio. Its tough to know which behind axle was supplied by World cars 1972 come calculate height speed. 116 MPH is much higher than the observed optimal speed Motor Trend completed in their tests.

The clerk spec guide for 1972 says that the conventional transmission and also axle for the 350-4 barrel the was traditional in the Cutlass supreme was the M38 automatically paired to the 2.73:1 axle. The 3.08:1 and 3.23:1 to be optional.

The figures quoted in World car 1972 for the basic Motors 1972 "A body" intermediates differ wildly despite the cars making use of the very same frames and similar body shapes and also horsepower ratings.

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

It seems the famous Rocket 350 Oldsmobile engine is ideal of all the engines follow to World cars 1972 with 116 MPH, however it can simply be that the different division engineers approximated the ns in peak speed due to compression fall using different formulas. The World cars 1972 book quotes numbers using the hand-operated 3 rate transmission. The salesman"s guide shows axle ratios noted with the manual transition 3 rate transmission and the M38 TH350 automatic as viewed below.

World dare 1972 receives your performance numbers from the manufacturer. The gas consumption World cars 1972 come up with is based on a moderately loaded Cutlass Supreme covering variable terrain at around 60% of height speed, which would be around 67 MPH.

OOCC CUTLASS supreme DRIVING CONDITIONS:

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

The 3,627 pounds quoted is technically correct but unrepresentative that the bulk of Cutlass supreme 2 door convertible cars built due to the fact that the base car is listed with the lightweight 3 speed manual transmission in World car 1972. Obviously a high end vehicle like this convertible doesn"t stand pat with the standard hands-on transmission, but listing a stripped car is a time honored tactic offered to mitigate the quoted basic price.

Below is a summary of the OOCC Cutlass Supreme alternatives and the weight increase above the base 350 4 bbl manual transmission "stripped" 2 door convertible:

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

The curb weight of the OOCC Cutlass can be fried totals 3,860 pounds add to a few more pounds because that miscellaneous options such as the electrical clock, bucket seats, console, dual custom sport mirrors v driver remote and so on. A realistic complete would be about 3,880 pounds. Include 200 lbs because that driver or miscelanious items and also the as moved weight was approximately 4,080 pounds.

The conventional tires top top the Cutlass supreme convertible were F78x14 v G70x14 and also G78x14 optional. If the optional 455 was set up or if A/C was included to the 350 engine climate the traditional tire dimension bumped up to G78x14.

The owner"s manual permits for a soft high-end ride through recommended light fill pressures (up come 750 pounds) the 24 PSI front and rear. Heavier loads than 750 pounds forced 26 PSI front and also 28 PSI rear.
