For the first couple of years, sport and muscle cars sell well, then slowly drop off as buyers flock to the latest and greatest.

Since its launch in 2008, the Challenger has shown a positive trend in U.S. sales.

According to Dodge, it sold 54,314 Challengers last year, which outsold the Ford Mustang by 1,900 units.

That tells us a lot about the Challenger's endurance. The question is, what is secret?

There's no simple answer, but there's no denying the designers hit it out of the park with their retro-inspired creations.

A 6.1-liter HEMI V8 engine pumping out 425 hp (317 kW / 431 PS) and 420 lb-ft (569 Nm) of torque also plays a crucial role in this model.

Eventually, it was replaced with a 6.4-liter HEMI V8 with 470 horsepower and 470 lb-ft (637 Newton meters).

Hellcat, Demon, and Hellcat Redeye models were introduced by Dodge over the years.

A 594 kW (708 PS) engine makes 684 hp (594 kW / 808 PS), while a 287 lb-ft (389 Nm) engine makes 287 lb-ft (389 Nm).

The high-performance models grabbed a lot of attention, but Dodge didn't neglect its mainstream models.
