FactIn 1966 a Comet Cyclone GT convertible paced the Indianapolis 500 — serious racing credibility for what had started out as a humble compact six years earlier.
Beginning in 1966 the Comet grew from a compact to a mid-sized car, now on the same chassis as the Ford Fairlane intermediate (the platform the previous-generation Comet shared with the Ford Mustang passed to the Mercury Cougar): 116.0 in wheelbase (113.0 in for wagons), 203 in long, 73.8 in wide and 54.3 in high. The 1966 Comet received distinct outer body panels; the Comet Capri replaced the 404 and the Comet Voyager four-door wagon replaced the 404 wagon, the 202 wagon was discontinued and the new top series was the Comet Cyclone GT; the wagon introduced a Dual-Action tailgate, able to fold down or swing aside. New engines for 1966 were the 390 cid V8 with a two-barrel carburetor (265 hp at 4400 rpm), a four-barrel version (275 hp) and a 335 hp 390 that was standard on the Cyclone GT and optional on other models (a GT with automatic transmission was the Cyclone GTA). Beginning with 1967 the Comet name was used only on the base Comet 202, available only as a two- or four-door sedan, with the other models known by their former subseries names (Capri, Caliente, Cyclone, Cyclone GT, and the steel-sided Voyager and wood-paneled Villager wagons). Engines on the infobox are the 200 Thriftpower Six, the 289 Challenger V8 and the 390 FE V8; the 1967 427 Comets are recorded as their own generation.

Mercury's 1971 Comet was really a dressed-up Maverick, and it didn't even get its own taillights — the pods were carried over straight from the 1970-71 Montego and Cyclone.

By 1968 the once-diverse Comet lineup had been stripped down to one body style only — a two-door coupe, sharing its chassis with the Ford Fairlane and Torino.

Only 60 1967 Comets ever got the 427 V8, and of those, just nine were W-code — with a single W-code Capri making it, by one account, the rarest Mercury ever built.

In 1966 a Comet Cyclone GT convertible paced the Indianapolis 500 — serious racing credibility for what had started out as a humble compact six years earlier.

Ford split its drag-strip muscle on purpose: the Comet Cyclone ran on wider tires in a different class than its Thunderbolt sibling, so neither car had to beat the other to dominate.

This Comet was almost an Edsel: it was conceived as one before that brand collapsed, and the first-year cars literally used Edsel parking lights and dashboard knobs left over in the parts bin.
Rivals
Same body, same money, other badges — tap any card to flip.

It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.

Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.

A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.

The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.

The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.

The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.

The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.

This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
