A Porsche production model and how to measure engine power

Drawing Board

2019 Porsche Taycan: Mission E was the working title for Porsche’s first electric car, but the production model will be called the Taycan. The company says the name means “lively young horse,” and, with 600-plus horsepower, this four-passenger, four-door model will be just that. Porsche claims the two electric motors will push the Taycan to 100 km/h (62 mph) from rest in 3.5 seconds. The stated range is 300 miles, and, with new 800-volt charging technology, the Taycan can reportedly receive an 80-percent charge in about 15 minutes.

Auto Trivia

• France was the first country to require license plates back in 1893. Eight years later, they became mandatory in the state of New York.

What’s up, auto doc?

Two cars have the same horsepower rating, but one “feels” stronger. Why? Given two identical cars (weight, gearing, transmissions, etc.), there is only one explanation: comparing the peak power of one engine to that of another is actually NOT a barometer of real-world power. The first thing to consider is that the peak horsepower of the “peppy” engine might occur at a more often realized rev limit, say 4,000 revs per minute instead of 6,000. The second factor is how much overall power each engine makes rather than focusing on peak power. A true comparison can only be made by examining the power of each engine at all revs. If you graphed the power versus r.p.m. of both engines, you could actually compare the area below the line. More area equals more overall power. Lacking this, you can simply compare the power in the r.p,m. range in which you do the most driving such as between 2,500 and 4,000 revs per minute.
