An SC-1 Stock Car is a stock car specification first introduced in 2010 for the World Stock Car Championship. All cars are based on mid-sized or larger production vehicles, and are powered by 3.4 liter turbocharged hybrid V6 engines. The body shell must resemble the production vehicle, and teams are responsible for their own engine development. However, the suspension must make use of standardized components; this serves as both a measure of cost control and ensures a more level playing field.
Technical Regulations[edit | edit source]
On August 19, 2009, technical regulations for the SC-1 stock car were announced; they underwent revisions in 2016, coinciding with the introduction of the next generation of stock car for the series.

Electric Variant[edit | edit source]
Provisions for an all-electric variant of the SC-1 Stock Car were announced in 2019, one year after the formation of the Stock Car E-Series. The variant, dubbed the SC1-08E, utilizes the same spec chassis provided by Stock Car Technologies, Inc. Unlike other series, SCTI is also contracted to provide a spec power unit and charging system capable of 800kW of rapid charging, allowing the entire battery system to be recharged during a standard pit stop. Teams are authorized to design their own drive motors within homolgomation rules, or are able to purchase from other teams or Stock Car Technologies; cost controlling measures aim to keep the price under $150,000.
The dashboards are a key difference from the driver's perspective; the dashboard of an SC1-08E stock car displays far more information and is almost fully digital, allowing for more customization than a standard dash board.
