AMC Eagle

In 1980 a small car company in Kenosha, Wisconsin put full-time four-wheel drive under an ordinary family car. Nobody had a name for it yet. Today we call it a crossover.

A Jeep engineer, a Concord, and a bad year for gas

By 1979 American Motors was in trouble. The second oil crisis had hit, and sales of its profitable but thirsty Jeeps were falling. Its passenger cars, the Concord and Spirit, were solid and cheap but getting old. AMC needed something new and couldn't afford to design a car from scratch.

Roy Lunn, AMC's chief engineer for Jeep, had an idea he called Project 8001 plus Four: take the car AMC already built and give it the four-wheel drive AMC already knew. In February 1977 the British firm FF Developments built a prototype on a V8 AMC Hornet. Testing pushed the design toward more ground clearance, 15-inch wheels, a near 50/50 torque split, and AMC's own 258 straight-six with an automatic.

The result went on sale in August 1979 as the 1980 Eagle: a Concord body raised three inches, with plastic fender flares to fill the gap, sitting on a permanent all-wheel-drive system. It rode like a car and went through snow like a Jeep. At the time it was the only four-wheel-drive passenger car built in the United States.

It sold from day one. Demand was strong enough that AMC killed the Pacer in December 1979 to free up assembly-line space in Kenosha for more Eagles.

Year by year

  1. 1977

    The prototype

    AMC hires FF Developments to build a four-wheel-drive Hornet. Roy Lunn's team refines it toward a six-cylinder, automatic, even-split car.

  2. 1980

    Launch

    Two-door, four-door and wagon, all on the Concord body with permanent 4WD and the 258 six. 45,379 built in the first year, more than half of them wagons.

  3. 1981

    SX/4, Kammback and Sundancer

    The smaller Spirit-based SX/4 hatchback and Kammback arrive, along with a GM 2.5-litre four. Griffith converts Limited two-doors into the Sundancer convertible. A Select Drive switch for 2WD appears mid-year.

  4. 1982

    Select Drive for everyone

    A dashboard switch lets every Eagle run in rear-wheel drive to save fuel. A five-speed manual joins the options list. The wagon outsells everything else combined.

  5. 1983

    Trimming the line

    The Kammback and the big two-door are gone. The six gets higher compression, a knock sensor and feedback fuel control.

  6. 1984

    Moving to Canada

    The SX/4 is dropped, leaving the sedan and wagon. Production moves to Brampton, Ontario, because Kenosha is building Renaults. Select Drive gets a new switch.

  7. 1985

    Shift on the fly

    You can now switch between 2WD and 4WD while moving. The power-bulge hood goes on every Eagle, and keyless entry becomes an option.

  8. 1987

    Chrysler buys AMC

    The buyout becomes official on 5 August 1987. The new fuel-injected 4.0 goes into the Jeep Cherokee, not the Eagle.

  9. 1988

    The last one

    Sold only as the “Eagle Wagon,” still wearing AMC badges. The final car leaves Brampton on 14 December 1987. Chrysler keeps the Eagle name for a new brand until 1998.

How the four-wheel drive worked

Most four-wheel-drive vehicles of the time used part-time systems that bound up on dry pavement. The Eagle could stay in four-wheel drive everywhere, all the time.

One propshaft runs back to the rear axle; another runs forward alongside the engine to a front differential bolted to the engine block, which drives the front wheels through half shafts. 258 six auto Front diff on the engine Viscous coupling Front propshaft Rear propshaft Rear axle Front of car Ice Disconnected

The viscous coupling

Behind the TorqueFlite automatic sat a New Process 119 transfer case with no low range. Inside it, closely spaced wavy plates turned in what AMC described as a honey-like silicone fluid. When the front and rear axles turned at the same speed, the fluid let them slip gently, so there was no binding on dry roads. When one end started spinning, the fluid thickened and sent torque to the end with grip.

Independent front suspension

AMC bolted the front differential directly to the engine block and ran half shafts with universal joints out to the wheels. That kept the car's normal independent front suspension, so the Eagle steered and rode like a Concord instead of a truck. It was the first mass-produced American four-wheel-drive car to do this.

Select Drive

From 1982 a dashboard switch disconnected the front axle and propshaft to save fuel. Early cars had to be stopped, and it took two hands. From 1985 you could shift on the fly.

Built not to rust

Every exterior panel was galvanized steel, the body went through an epoxy primer bath up to the window line, and the car had plastic inner fender liners. Each Eagle came with Ziebart rust protection and a five-year no-rust-through warranty.

Six ways to buy one

The larger Series 30 cars used the Concord body. The smaller Series 50 cars, added in 1981, used the Spirit. For engines, axle ratios and production by year, see the specs page; to find out exactly what your car left the factory as, try the VIN decoder.

Eagles built each model year

Strong at launch, a bump in 1984, then a long fade once AMC stopped advertising the car.

Sources differ for 1985 and 1987. For 1985 the chart uses 16,008, the total that matches the published body-style counts (Wikipedia's 16,990 does not add up). For 1987, figures range from 5,018 to 5,922; the chart uses 5,922. See production by body style on the specs page.

How AMC sold it

AMC's ad budget was small, and it pitched the SX/4 as “the 2-wheel/4-wheel drive Eagle” and “driving in the 4th Dimension.” These original 1980s magazine ads are in the public domain.

AMC ad: The first sport machine that doesn't always need a road. Eagle SX/4.
AMC ad: When the slopes are great, the roads are rotten. A black SX/4 in snow.
AMC ad: For the snow, for the surf, for the slippery, for the steep, for the sporty, for the stylish, for the smart.
AMC ad: Experience what lies beyond the sports car. Eagle SX/4.

It went rallying, too

From 1981 the SX/4 ran in the SCCA ProRally series. Guy Light and Jim Brandt finished the 1981 Northern Lights rally three minutes off the class lead despite hitting a tree dead centre in their brand-new car. They won the Production class at the season finale in Reno by eight minutes and finished the year second in points.

Gene Henderson and Jim Kloosterman kept it going through 1983, winning the snowy Nor'wester outright in class. “It was perfect conditions for our 4wd Eagle,” they said. “We love that slop.” AMC finished third among production manufacturers three years running.
