The Challenger's longer wheelbase, larger dimensions and more luxurious interior were prompted by the launch of the 1967 Mercury Cougar, likewise a bigger, more luxurious and more expensive pony car aimed at affluent young American buyers. The wheelbase, at 110 inches (2,794 mm), was two inches longer than the Barracuda, and the Dodge differed substantially from the Plymouth in its outer sheet metal, much as the Cougar differed from the shorter-wheelbase Ford Mustang. Air conditioning and a rear window defogger were optional.

Exterior design was done by Carl Cameron, who also did the exterior for the 1966 Dodge Charger. Cameron based the 1970 Challenger grille off an older sketch of his 1966 Charger prototype that was to have a turbine engine. The Charger never got the turbine, but the Challenger featured that car's grille. Although the Challenger was well received by the public (with 76,935 produced for the 1970 model year), it was criticized by the press, and the pony car segment was already declining by the time the Challenger arrived. Sales fell dramatically after 1970, and though sales rose for the 1973 model year with over 27,800 cars being sold, Challenger production ceased midway through the 1974 model year. A total of 165,437 Challengers were sold over this generation's lifespan.

The Challenger was available as a two-door in either a hardtop coupe or a convertible body design, and in two models for its introductory year. For 1970 only, base hardtop and R/T hardtop models could be ordered with the more luxurious SE specification, which included leather seats, a vinyl roof, a smaller 'formal' rear window, and an overhead interior console that contained three warning lights (door ajar, low fuel, and seatbelts). The base model was the "Challenger" with either a I6 or V8 engine, as well as a "Challenger R/T" that included a 383 cu in (6.28 L) V8. The Special Edition or "Challenger SE" that added a number of appearance, convenience, and comfort items was "available as a model in either the Challenger R/T or Challenger." The standard engine on the base model was the 225 cu in (3.7 L) six-cylinder. The standard engine on the V8 was the 230hp (171.5 kW) 318 cu in (5.2 L) V8 with a 2-barrel carburetor. For 1970, the optional engines included the 340 and 383 cu in (5.6 and 6.3 L), as well as the 440 and 426 cu in (7.2 and 7.0 L) V8s, all with a standard 3-speed manual transmission, except for the 290hp (216.3 kW) 383 CID engine, which was available only with the TorqueFlite automatic transmission. A 4-speed manual was optional on all engines except the 225 CID I6 and the 2-barrel 383 CID V8.

In 1972, the R/T badging was dropped and these models were called "Rallye", although they were never badged as such. The Rallye model featured a faux brake vent on the fenders. The shaker hood scoop was not available after 1971.

A 1970-only model was the Dodge Challenger T/A (Trans Am) racing homologation car. In order to race in the Sports Car Club of America's Trans American Sedan Championship Trans Am, Dodge built a street version of its race car (just like Plymouth with its Plymouth 'Cuda AAR) which it called the Dodge Challenger T/A (Trans Am). Although the race cars ran a de stroked version of the 340, street versions took the 340 and added a trio of two-barrel carburetors atop an aluminum intake manifold, creating the 340 Six Pack. Dodge rated the 340 Six Pack at 290hp (216.3 kW), only 15hp (11 kW) more than the original 340 engine (which also had the same rating as the Camaro Z/28 and Ford Boss 302 Mustang). The engine actually made about 320hp (238.6 kW). It breathed air through a suitcase-sized air scoop molded into the pinned down, hinged matte-black fiberglass hood. Low-restriction dual exhaust ran to the stock muffler location, then reversed direction to exit in chrome tipped "megaphone" outlets in front of the rear wheels. Options included a TorqueFlite automatic or pistol-grip Hurst-shifted four-speed transmission, 3.55:1 or 3.90:1 gears, as well as manual or power steering. Front disc brakes were standard. The special Rallye suspension used heavy duty parts and increased the rate of the rear springs. The T/A was one of the first U.S. muscle car to fit different size tires front and rear: E60x15 Goodyear Polyglas in the front, and G60x15 on the rear axle. The modified chamber elevated the tail enough to clear the rear tires and its side exhaust outlets. Thick dual side stripes, bold ID graphics, a fiberglass ducktail rear spoiler, and a fiberglass front spoiler were also included. The interior was identical to other Challengers. Only 2,399 T/As were made.

The 1970 taillights went all the way across the back of the car, with the backup light in the middle. In 1971, the backup lights were on the left and right instead of the middle. The taillight array also changed for 1972 onwards, with the Challenger now having four individual rectangular lamps.
