When an automaker introduces a new model, they hope that it will be so popular that they can keep producing it indefinitely. There have been some legendary vehicles throughout automotive history that have been in production for decades—cars like the 911, one of Porsche's greatest sports cars. The Ford F-150 pickup truck that has been among the best-selling vehicles in the US for decades, or the Honda Civic, one of the most reliable family cars of all time.

However, there have been many vehicles that, despite being great, were discontinued for reasons such as low sales, high production costs, technological obsolescence, and a whole host of other reasons. This list delves into ten discontinued sports cars that every gearhead wishes would come back.

10 Jaguar XJ220

The Jaguar XJ220 is regarded as one of the greatest sports cars of the 90s – which is a huge achievement considering it started as a side project by an informal group of Jaguar employees. After building the XJ220 concept and showing it at the Birmingham Motor Show, Jaguar instantly received more than 1,000 serious orders for the powerful sports car, forcing them to put it into production.

Unfortunately, engineering and emission requirements forced Jaguar to make significant changes to the XJ220's specifications, most notably the replacement of the V12 engine by a turbocharged V6. These changes led to a collapse in the car's demand. In the end, only 275 examples were built, each with a price of more than $500,000.

It also had a 1,558cc DOHC engine, rack and pinion steering, four-wheel disc brakes, and a four-wheel independent suspension.

The S2000 was an open-top sports car manufactured by Honda from 1999 to 2009. It was first launched to celebrate Honda's 50th anniversary and quickly grew in popularity due to its front mid-engine, rear-wheel-drive layout and the fact that it had the highest specific power output of any naturally-aspirated engine car.

The engine in question was a 2.0-2.2L four-cylinder VTEC unit producing 247 horsepower. After almost a decade of steady production, the S2000's sales started falling in 2006, a trend that was accelerated by the 2008 economic crisis. Honda finally discontinued the S2000 in 2009 after selling 110,673 units.

Regarded as one of the most excellent Japanese sports cars from the 80s, the MR2 enjoyed a successful production run for almost two decades. However, sales started falling in 2000 due to increasing competition, eventually forcing Toyota to discontinue the MR2 in 2005 in the US and 2007 globally.

Surprisingly, the Fiat Chrysler group announced ending the Viper's production in 2017. The company cited dwindling sales as the reason for the discontinuation, but other sources claimed that the reason was that the Viper couldn't comply with some safety regulations.
