    These days, Daimler-Chrysler offers cars with engine options ranging from a
    Straight-Four to a Vee-Ten. They tell you this or that engine is rated for
    xyz horsepower, but that tells you absolutely nothing about the car's
    performance. As you know, top speed and acceleration isn't even advertised
    anymore and even it it was, its all meaningless:

    All parameters must be rated with a full fuel tank and full passenger and
    baggage load.
    Car should be capable of 75 mph (Interstate speed limit) up 6% (Interstate
    grade limit) at 7500 feet elevation (Interstate max elevation) on a
    standard day (temp/pressure). Brakes should be capable of making at least
    one full stop from 75 mph to zero, at full load, at 0.75 g. A salom test
    needs to be designed to demonstrate steering performance to the limits of
    road adhesion and of course, the vehicle must not roll (no outrigger
    allowed for the test and the company CEO must ride as a passenger to
    observe first hand).

    That's it! A car that can do this will accelerate adequately, have
    adequate top speed, brakes, steering, etc. Anything less is a dog and
    anything more is wasteful.

    To make this point stronger, I once drove a '74 Bel-Aire with a 327 V-8 and
    Turboglide up the Grapevine at Tehachipi (US-99) on a warm evening, loaded
    with three adults and baggage and 3/4 tank. It would not exceed 55 mph!
    What a dog. If it makes you feel any better, the '50s cars were dogs too;
    they went faster for a short while untile their valves warped, some of them
    at least, but they wouldn't stop...something called heat glazing and brake
    fade; if they got wet, say your prayers.

    You skeptics will lay praise upon your new cars as being so much better
    than earlier models you drove, but only because you don't have anything
    decent to compare to. Your cars of old were junk with a capital J; your
    new models are junk with a lower-case j.

  2. Certainly are in Europe and most other places. Are we having a touch of
    talking through our left nostril?
