The 1970 Chevelle featured further restyling from the 1969 model. Each head lamp was put in its own chrome housing and was no longer integrated into the grille.
The body lines were less swept and a new integrated rear bumper was used. The body was similar to the 1969 Chevrolet Chevelle, but some consider the 1970 model to be the best-looking Chevelle of all. With the 454 cubic inch big block now available in the form of the LS5 & LS6, the 1970 Chevelle symbolizes the height of the muscle car era.
The 1970 Chevelle was available in several trim levels including the base Chevelle, Chevelle Malibu, Chevelle Concours Estate, Chevelle SS396, and new SS454. Each configuration could be ordered with a six-cylinder (except SS) or V8 engine. Body style included 2 door sport coupes, 2 door sedans, 2 door convertibles, 4 door sedans, or 4 door wagons.
Interiors could be optioned with either bucket seats or bench seats and were available in many colors. The most popular were Black, Bright Blue, Dark Metallic Green, Pearl, Red, Saddle, or Gold. The buyer could have ordered a number of different exterior colors including White, Cortez Silver, Shadow Gray, Tuxedo Black, Astro Turquoise Blue, Fathom Blue, Misty Turquoise, Green Mist, Forest Green, Gobi Beige, Champagne Gold, Autumn Gold, Desert Sand, Cranberry Red, and Black Cherry.
To complement the wide variety of available colors were the available drive train combinations that could be opted for. Base power was had by one of two available six-cylinder. Buyers who wanted more power could opt for a V8. Big blocks were in abundance with the regular availability of both 396 and 454 cubic inch engines for the SS 396 & SS 454 packages.
Manual transmissions were either 3 speeds or 4 speeds and automatic transmissions were either the 2 speed Powerglide or 3-speed Turbo Hydramatics, including the Turbo 350 and Turbo 400 for small block & big block engines respectively.
About 634,000 1970 Chevrolet Chevelles were produced in total.
