57 mpg? That's so 20 years
ago
Want to drive a cheap car that gets eye-popping mileage?
In 1987 you could - and it wasn't even a hybrid.

1987 Honda Civic CRX HF
Car makers are confident they can meet new government rules calling for
a national fleet average of 35 miles per gallon.
But it will take a big technological push, they say.
You might wonder why, since twenty years ago the car that got the best mileage
in the nation was a real techno-wimp compared
to what's on the road today. It wasn't even a hybrid. But it got better fuel
economy than any car sold now - even the Toyota Prius.
Looking back at the 1987 Honda Civic CRX shows us why cars use so much more
gas today and about the trade-offs we've
had to make.
The CRX HF got an Environmental Protection Agency-estimated 57 mpg gallon
in highway driving. Today, the most fuel-efficient
non-hybrid Civic you can buy gets an EPA-estimated 34 mpg on the highway.
Even today's Honda Civic Hybrid can't match it,
achieving EPA-estimated highway mileage of just 45 mpg. The Toyota Prius,
today's fuel mileage champ, gets 46 mpg on the
highway.
Why then, not now?
One answer for the mileage drop is that the rating system has changed. Beginning
with the 2008 model year, the EPA began
using a more rigorous fuel economy test that means lower numbers for most
cars. But that's only a small part of the answer.
If the old CRX HF were tested using today's rules, its highway fuel economy
would drop to 51 mpg, according to the EPA's
calculations. That's still much better than any mass-market car sold today,
including hybrid cars.
The bigger answer is that the Honda Civic has changed a lot in twenty years.
Honda no longer sells a tiny two-seat version like
the CRX. Even Civics with back seats are much bigger and heavier today than
similar versions were in 1987.
It's in the nature of the car business that companies want to offer more
- more legroom, more trunk space - with each redesign.
As a result, cars get bigger and bigger.
Besides size, American consumers expect a lot more convenience out of a
car than they did in 1985.
Today, we expect power steering, power brakes, power windows and more.
The base CRX HF did not have power steering or power brakes. (As light as
it was, it really didn't need them.)
Air conditioning was optional, as it was on most cars in those days, so it
didn't figure into the EPA's fuel economy ratings.
Today's consumers also expect safety. In the 1980s, car companies would
sell cars that got one-star or two-star crash test
ratings. Numbers like that would now cause car companies fits. Four out of
five stars is considered the minimum acceptable rating.
The modern Civic has airbags front and side, electronic stability control
and built-in crash protecting structures in the body.
Even the CRX's biggest fans wouldn't relish the thought of getting into
a wreck in one of those cars. While actual crash test results
are not available, even a Honda spokesman admitted the car probably wouldn't
have fared well by modern standards.
Without the benefit of modern crash structure and extensive use of high strength
steel, cars from two decades ago couldn't
match the crash test performance of today's Hondas.
Increased safety, meaning more weight from airbags and crash structure,
has meant lower fuel economy.
It's kind of a classic engineering fight where safe cars compete with more
fuel-efficient cars.
Not that the economy CRX was a bad car. Far from it. Even before Honda introduced
a performance version called the
CRX Si, the lightweight, fun to drive Civic CRX.
Even in its base HF trim, the CRX was considered a fun car to drive because
it was small and responsive.
Its zero-to-sixty time, though - about 12 seconds by some estimates - would
put it well behind even a large, sedate family
sedan like the Ford Five Hundred Taurus today.
Weighing less than 1,800 pounds, the CRX HF was powered by a 58-horsepower
engine. Today's base Honda Civic
weighs almost 2,600 pounds and is powered by a 140 horsepower engine. That's
about 12.5 pounds less weight per pony
today, despite greatly increased size.
The lightest cars you can buy today are about 40 percent heavier than the
old CRX.
Comparing essentially similar Honda Civic sedans from the 1980s and today
reveals that today's car gets considerably
better fuel economy (40 highway mg vs. 32) despite having a larger engine
with much more power (140 horsepower vs. 76).
Daimler is about to find out how much appetite American's now have for inexpensive
little two-seat cars that emphasize fuel
economy over performance. It's just begun selling the tiny Smart ForTwo in
the USA. But even the ForTwo, which is much smaller
than the CRX, will get about 41 mpg on the highway, according to Daimler.
(Official EPA estimates aren't out yet.).
Rumors swirl today, as they have for years, that Honda is planning to bring
out a modern version of the CRX.
This time, though, the CRX HF would have to be a hybrid. (Perhaps the one
the company just announced it will make for 2009.)
There just isn't any other way to pull that off today.
