    40-60 mph: '67 Ferrari VS '64 Cadillac

    I was looking through a Car & Driver magazine (July, 1967) at a comparison test between a '67 Mercury Cougar XR-7 and a '67 Jaguar 420. Also in the issue was a road test of a '67 Ferrari 330/GTC and I noticed the 40-60 mph time was 3.5 seconds. I remember a Car Life (July, 1964) test of a '64 Cadillac in which the 40-60 mph was 3.7 seconds. Surprising that the Cadillac had such as close time. As most people know, once the weight is overcome, big and heavy cars can have some good passing times.

    Here are the actual specs:

    ---------------------------- '67 Ferrari--------------- '64 Cadillac
    ---------------------------- 330/GTC---------------- Sedan de Ville

    Engine---------------------- V-12 242-cu-in/3,967 cc- V-8 429-cu-in
    Rated horsepower----------- 300 @ 7000 rpm--------- 340 @ 4600
    Rated torque---------------- N.A.-------------------- 480 lbs/ft @ 3000
    Compression ratio----------- 8.8:1-------------------- 10.5:1
    Transmission---------------- 5-speed manual---------- 3-speed auto
    Axle ratio------------------- 3.44:1------------------- 3.21:1
    Curb weight----------------- 3,160 lbs---------------- 4,900 lbs

    Wheelbase/length----------- 94.4"/177.4"------------- 129.5"/223.5"

    0-30 mph------------------- 2.2 secs----------------- 3.4 secs
    0-60 mph------------------- 6.8---------------------- 8.5
    0-80 mph------------------- 11.3--------------------- 14.1

    1/4 mile--------------------- 15.1 @ 96 mph----------- 16.4 @ 86 mph

    40-60 mph------------------ 3.5 secs------------------ 3.7 secs
    50-70 mph------------------ 4.1----------------------- 4.5
    30-70 mph------------------ 6.7----------------------- 7.6

    Top speed------------------ 153 mph (estimated)------- 121 (observed)

    Speed in gears @ rpm (mph)
    1st------------------------- 50 @ 7000 rpm------------ 46 @ 4400

    With such a vastly bigger engine, the torque surge would be nice at that speed range. Also the Caddy probably didn't have to change gear. Interesting thing - seems the Caddy has a very high compression ratio for the time, or was that pretty normal?

    It would be nice... even when pushing a 4,900-lb car.

    Going by the specs listed, it looks like each car was shifted one time during the 40-60 mph run.

    No, I would say it was normal. Even the big luxury cars (Cadillac, Lincoln, Imperial) had high-compression engines. At least until 1970-'71.

    Big V8s on leaded gas from that era had some quite impressive compression ratios.

    So a 7 litre car is more suited to in-gear acceleration than a 4 litre one.

    In other news scientists from the MIT say water is wet.

    Probably.

    Do you mean a 7 litre car which weighs almost two tons more than a 4 litre one?

    No doubt, many people would be surprised at the slight difference in 40-60 mph times. I sure was.

    If the Ferrari had stayed in 2nd gear it might have been quicker...

    the torque of the Ferrari is 240 lbft at 5000 revs, which is half that of the Caddy....

    Thanks for the torque figure.
    Yes, the Caddy has a lot more torque but who really expected a '64 Cadillac to almost keep up with a Ferrari in 40-60 and 50-70 mph acceleration?

    According to the chart, 2nd gear was used up to 72 mph, so it looks like it was in 2nd gear for the 40-60 mph acceleration. Or did you mean 1st gear?

    I doubt it was using the "appropiate" gears for maximum acceleration, but rather taller gear to see the flexibility of the engine.

    Hence my earlier comment.

    Looks like they were using appropriate gears for maximum acceleration... they were going all the way up to the redline (7,000 rpm) in each gear except for 5th. Not much sense listing acceleration times if they are not trying for maximum acceleration.

    Maybe not. The figures speak for themselves.

    This is yet more proof that what you really need to be a speed freak is a...

    2006 Toyota Camry SE V6!

    According to a test from Road and Track, it will hit 60 mph in 6.1(!) seconds, and roll through the quarter at 14.5 at tarmac tearin' 99.9 mph!

    It's DOHC 3456 cc engine will pump out an earth shattering 268 hp at 6,200 rpm, and 242 lb.-ft. of torque at 4,700 rpm - with a compression ratio of 10.8:1! This is at a test weight of 3,670 lbs and with an R/T observed mileage of 26.3 mpg, and an EPA city/highway rating of 21/29!

    You also have the easy, predictable, and safe handling charactersitics of a front-wheel drive car! On the skidpad and slalom, R/T reported moderate understeer! What more can you ask for friends?!

    All that for only $27,350 USD in 2006 monies!

    Now that, is a reliable, comfortable, and fast car! Women will respect your rational car purchase and you can leave lesser cars (such as American iron and Italian exotica from the '60s) in your dust!

    Pick one up on the second hand market and it will last you another 10 years! You won't have to worry about rust on that Caddy or filling her up with gas at 1.35 a litre, or paying for exorbitant repair fees and a gobsmacking upfront price for that 330!

    Step on down to your local Toyota dealership and get a certified pre-owned 2006 Camry LE V6 today!
