• The 2025 Porsche Taycan continues to under-promise and over-deliver.
• In a new 70 mph highway range test, the Taycan blasted past its EPA rating.
• It did that in cold-ish temperatures while running on winter tires.

When Porsche launched the Taycan around the turn of the decade, it got rave reviews for its performance but didn’t really earn a reputation for efficiency. At least initially, road-tripping wasn’t its forte. But Porsche kept improving the Taycan over the years, with bigger batteries and a more efficient powertrain.

Now, it’s one of the best EVs for chugging miles. It beat its EPA range in several other tests and that was reinforced in the latest range test conducted by Tom Moloughney, the host of the State Of Charge YouTube channel and a contributor to InsideEVs.

Moloughney drove the Taycan 4 Cross Turismo, the more rugged, wagon version of the Taycan. The entire lineup gets the bigger Performance Battery Plus for the 2025 model year, capable of 97 kilowatt-hours of usable battery capacity in its 105-kWh gross package. Only the entry-level Taycan sedan gets a smaller 82.3 kWh battery.

The EPA range of the Taycan 4 Cross Turismo is about 277 miles, 42 miles better than the previous model year. But this particular Taycan was riding on winter tires, with larger tread patterns optimized for grip in snow, not efficiency. Their rolling resistance is higher than summer tires, which compromises driving range. Moloughney also drove in loops around the New Jersey Turnpike, his standard route for the 70 mph range tests.

The climate was set to 70 degrees Fahrenheit on the lowest fan speed and the driving mode in its most efficient setting. It’s also worth noting that this Taycan trim gets a dual-motor all-wheel-drive set-up with a max output of 439 horsepower. It’s not meant to be driven gently, but if you do, you’ll be surprised by how far it can go.

Due to the winter tires, Moloughney expected the Porsche to fall short of its EPA range. But what happened was quite the opposite. After consuming 50% of the energy, the Taycan had already covered 157 miles. In the second half of the test, the Taycan covered another 145 miles, taking the total to 302 miles, blasting past its EPA range by 25 miles.

“I’m flabbergasted,” Moloughney said of the Taycan’s efficiency.

However, the final mile was used to crawl to the charging station. When he pulled up to the dispenser, the battery went to 0% and the car died. Porsches don’t get a buffer below 0%, Tom said, so you have to take the range reading seriously and not rely on the buffer because there is none.

The second leg of his range test was helped by warmer temperatures, which increased from around 50 degrees Fahrenheit to about 68 degrees before dropping back down. The test route was on mostly flat terrain. With normal summer tires, Moloughney estimated that Taycan Cross Turismo could even go 320 miles on a single charge.

“I really didn’t think that was going to happen,” he said.
