saw a major change in casting numbering. Since that moment, recolors are named with a different number than the original, thus causing the number limit of cars to expand to 365. The idea of numbering a casting with a number corresponding to their own series was also aborted. There were also some new mainline series introduced, such as Experimotors (cars with moving parts, or a secondary purpose), Holiday Racers (cars that have a holiday based theme), Factory Fresh (a series including newer, sometimes older castings with fabric painting) and Camaro Fifty (a series dedicated to the Chevrolet Camaro, and its 50th anniversary).

In 2011, Sizzlers have been re-released as Cars 2 characters, and were sold at Target stores. This line was called Charge Ups and released under the Mattel brand name but not as part of the Hot Wheels line. Edward, Kyle (December 9, 2019).

And last but not least, the RLC will offer a version of Ryu’s personal Acura NSX. Ryu customized his car after an obscure Suzuka Circuit pace car. To honor his memory, the Hot Wheels design team pulled out all the stops, giving the NSX working lights. Activated by pushing down on the spoiler, the lights cycle through multiple patterns such as all-on and alternating flashing. Incredibly, the car even has an interior, though a slightly shallower one the standard to accommodate the electronics for the lights.Miller, Aaron (January 8, 2016).

In some cases, Hot Wheels dies have been sold or acquired by other companies once Mattel has finished using them. One example were early dies that made their way to Argentina and were reproduced as Mukys, though not with spectra-flame paints or the same quality as seen in Mattel's products.

Hot Wheels has also released slightly larger, more detailed models, such as the original Gran Toros (1/43 scale) from 1970, and the Dropstars line (a model line of "blinged" cars). Also in this larger scale are the HIN ( Hot Import Nights), G-Machines and Customs lines. These lines were introduced in 2004–2005. However, 1972 and 1973 were slow years. Only seven new models were made in 1972. Of the 24 models appearing for 1973, only three were new models. Also the cars changed from Mattel's in-house Spectraflame colors to mostly drab, solid enamel colors, which mainstream Hot Wheels cars still use today. Due to low sales, and the fact that the majority of the castings were not re-used in later years, the 1972-3 models are known to be very collectible.

The year 1970 introduced " the Snake and the Mongoose", a manufactured 'rivalry' between two professional drag racers calling themselves "the Snake" and "the Mongoose" for the purposes of publicity. This was notably drag racing's first major non-automotive corporate sponsor, and the beginning of the NHRA’s booming popularity with large-budget teams and championships. 1970 also introduced the first 'Silver Series', which contained three silver-painted models: the Boss Hoss, the Heavy Chevy, and the King ' Kuda, which were only obtainable through a mail-in offer that included a membership to the Hot Wheels Club. These three cars featured " supercharged" engines (featuring large Roots blowers) without hoods, and open exhaust headers, after the style of drag racing cars of the era. Popular among children, these 'Silver Cars' were considered faster than the rest of the Hot Wheels lineup, because they were supposedly heavier than the other gravity models, but the accuracy of this claim has never been tested under scientific conditions. In 2008, all the series and vehicles were relatively similar to 2007's cars. approximately 180 to 200 new vehicles were released.
