Porsche’s best daily driver 911? The 2025 Carrera GTS T-Hybrid review.

Summary

The added displacement—0.6 L larger than the engine you'll find in the regular 911—is to compensate for not being able to alter the fuel ratio. And for the first time in several decades, there's now only a single turbocharger. Normally, a larger-capacity engine and a single big turbo should be a recipe for plenty of lag, versus a smaller displacement and a turbocharger for each cylinder bank, as the former has larger components with more mass that needs to be moved. The GTS engine grows in capacity by 20 percent. Porsche The GTS engine grows in capacity by 20 percent. Porsche I'll have to stop writing that F1 MGU-Hs have no road relevance now, because that's what Porsche has fitted to the GTS's turbocharger.

The traction battery is that silver box above the front axle. Porsche That's where one of the two electric motors comes in. This one is found between the compressor and the turbine wheel, and it's only capable of 15 hp (11 kW), but it uses that to spin the turbine up to 120,000 rpm, hitting peak boost in 0.8 seconds. For comparison, the twin turbos you find in the current 3.0 L 911s take three times as long. Since the turbine is electrically controlled and the electric motor can regulate boost pressure, there's no need for a wastegate. The electrically powered turbocharger is essentially the same as the MGU-H used in Formula 1, as it can drive the turbine and also regenerate energy to the car's traction ...
