Ford is ending production of its Mustang Boss 302.

Ford's track-focused Mustang Boss 302 looks to a be a two-and-done model run. A leaked order guide has revealed the 2014 Mustang lineup, with the Boss 302 conspicuously absent.

When Ford brought back the Boss 302 nameplate in 2012 after a four-decade slumber, it said that the performance Mustang would only be around for two model years. Ford is apparently keeping that promise as a leaked order guide obtained by fan site Mustang Daily makes no mention of the Boss 302 for the 2014 model year.

Although buyers will still have access to the V8-powered Mustang GT and Shelby GT500 for 2014, the Boss 302 will leave a gap in Ford's Mustang lineup. The Boss 302 bridged the gap between the GT and Shelby GT500 both in terms of performance and price, offering buyers an up-rated suspension, 444 horsepower and a starting MSRP of just over $42,000.

However, those looking for a 2014 model year muscle car with track credential won't be completely left in the dark. Chevrolet recently launched a 1LE package for its Camaro SS, which promises all of the performance of the Boss 302 but at a discounted price.
