In this special episode of Project Porsche, it is old vs new. Can an old 1999 Porsche 911 keep up with a new 2016 VW Golf GTI? The 911 may have more power, but is it quicker than a turbocharged GTI one mile above sea level where normally aspirated cars struggle in the thinner atmosphere. Watch this episode of Project Porsche to find out the answer.
hp loss = (elevation x 0.03 x hp @ sea level)/1000
The venue for this test was Bandimere Speedway near Denver, Colorado, which sits 5,800 feet above sea level. Using the equation above and the factory horsepower rating for a ’96 911 Carrera, the horsepower loss is approximately 51. This handicaps the Porsche to roughly 245 horsepower versus the GTI’s turbocharged 2.0-liter engine rated at 210 horsepower.
The ’96 Carrera weighs 2,901 pounds, which gives it a power-to-weight ratio of 0.8 horsepower per 10 pounds. The 2016 VW GTI weighs 2,972 pounds with a manual transmission and is calculated at 0.7 horsepower per 10 pounds. On paper, the older 911 still has the power advantage — even one mile above sea level. But can it hold off the turbocharged GTI at the finish line?
