FactPenske actually tested it: the 1971 Javelin AMX's rear spoiler was measured adding 100 lb of real downforce at Ontario Motor Speedway.
Starting with the 1971 model year the AMX was no longer a separate two-seater line: it evolved into a premium high-performance edition of the Javelin, the second-generation AMX being the first pony car used as a standard highway police vehicle by an American law enforcement agency. On top of the standard 360 cu in V8 it added engine-turned interior trim, a sports console, dual outside mirrors, a rear spoiler, 14×6-inch spoke-style wheels on E70×14 raised-white-letter fiberglass-belted tires, a heavy-duty clutch and a unique grille (with E60×15 tires on 15-inch slot-style wheels as the only tire upgrade), and AMC advertised it as "the closest thing you can buy to a Trans-Am champion". It had a fiberglass full-width cowl-induction hood and front and rear spoilers; testing at the Ontario Motor Speedway by the Penske Racing Team recorded that the 1971 rear spoiler added 100 lb of downforce, and Mark Donohue advised making the grille flush, so it got a stainless steel mesh screen over the standard Javelin's deep openings. The "Go Package" gave the choice of a 360 or 401 four-barrel with "Rally-Pac" instruments, a handling package, "Twin-Grip" limited-slip differential, heavy-duty cooling, power-assisted disc brakes, E60×15 Goodyear Polyglas tires on 15×7-inch styled slotted steel wheels, a T-stripe hood decal and a blacked-out rear taillight panel; the 3,244-pound 1971 AMX with the 401 ran the quarter-mile in the mid-14 second range at 93 mph on low-lead, low-octane gas. For 1974 the 304 V8 became standard for the AMX with the 360 optional in two- or four-barrel form, the functional cowl-induction hood was no longer available (its non-functional twin remained standard), and 4,980 AMX models were built, about 15 percent of that year's Javelin production.

The second-gen AMX wasn't just a street car — it became the first pony car any American police force put on regular highway patrol duty.
AMC unveiled the Javelin on the same day, August 9, 1967, that it discontinued the Rambler brand name in the US market.

The Celica XX, Japan's name for the A60 Supra, introduced the world's first in-car navigation computer.
The CTR Anniversary looks like a 911 but Ruf built its carbon monocoque from scratch, no Porsche body underneath.
The 228's coupe styling hides a sedan underneath: Maserati stretched it onto the longer four-door Biturbo chassis to make room for its biggest V6, which is literally where the name comes from — 2-door, 2.8 litre.
Switching to fuel injection let this V8 finally shed its trademark bonnet bulge — and only 405 of these flat-hooded Series 5 cars were built before the whole model retired in 1989.
Japanese buyers got a secret weapon in their MX-6 — the JDM-only KL-ZE V6 made about 40 more horsepower than the engine sold in the exact same car in North America.
An American tuner, Callaway Cars, built twin-turbo conversions of the GTV6 that boosted its V6 by fifty percent to 230 hp — turning Alfa's grand tourer into something far quicker than the factory ever intended.
