Review: The 2024 Porsche Cayenne Turbo E-Hybrid Adds Vitality to V-8 Offerings

32

In evaluating the 2024 Porsche Cayenne Turbo, the essential query pertains to your preference in V-8 engines: conventional or hybridized?

The updated 2024 Cayenne offers three iterations of its new twin-turbo 4.0-liter V-8: The Cayenne S introduces the engine with 468 horsepower and 442 lb-ft of torque; the Cayenne Turbo E-Hybrid refines its V-8 to deliver 591 horsepower and 590 lb-ft of torque; and the Turbo GT version achieves 650 horsepower and 626 lb-ft of torque. To my knowledge, this represents the broadest V-8 lineup available in any non-truck model for the year 2024.

This diverse offering may be short-lived.

2024 Porsche Cayenne Turbo E-Hybrid: A Transformation in V-8 Engineering

The 2024 Cayenne underwent significant revisions to its twin-turbo 4.0-liter V-8 engine, aiming to elevate power while minimizing emissions. Notably, the high-performance Turbo GT’s V-8 will not incorporate electric assistance and therefore won’t be available in European and most Asian markets.

The modifications to the V-8 are extensive. Dr. Christoph Oerleke, Cayenne’s product manager, informed AutoMotorMart that these adjustments encompass increased direct injection pressure to optimize combustion and minimize residual fuel in the cylinders. Enhanced variable valve lift and timing contribute to thermal efficiency. These changes essentially allow the V-8 to extract more energy from each unit of fuel. Improved electronic wastegates in the turbochargers enhance emission controls.

Upgrades in engine management have led Porsche to replace the twin-scroll turbochargers in all models except the GT with more compact, high-performing single-scroll turbochargers. This enhancement comes to the fore particularly as the engine approaches its 6,800 rpm rev limit.

Cylinder deactivation is no longer featured in the Cayenne Turbo V-8. The 2024 Cayenne Turbo E-Hybrid depends on a larger 25.9-kWh battery pack (an increase from 17.9 kWh) and a more robust 130-kW electric drive unit (up from 100 kW). This hybrid model relies solely on its V-8 at speeds exceeding 84 mph.

When questioned about the frequency of such high-speed driving, Dr. Oerleke promptly stated, “It happens in Germany,” subtly suggesting that German drivers often approach the Turbo E-Hybrid’s top speed of 183 mph.

Performance Evaluation of the 2024 Cayenne Turbo E-Hybrid on Track

During a test drive on the Parcmotor de Castelloli racetrack near Barcelona, the Cayenne Turbo E-Hybrid showcased its capabilities. The vehicle was equipped with an array of features that nearly matched those of the European Turbo E-Hybrid GT Pack, including rear-wheel steering, dynamic chassis control, 22-inch staggered wheels, and carbon-ceramic brakes.

In comparison to the more svelte Turbo GT, the Turbo E-Hybrid is considerably heavier, affecting its 0-60 mph acceleration time. However, the hybrid model compensates for this with a robust electric motor and battery, delivering a total system output of 729 horsepower and 700 lb-ft of torque—making it the most potent Cayenne to date.

The Turbo E-Hybrid executed impressively on straight runs in Sport+ mode, and its traction and air suspension systems effectively managed the vehicle’s heft. The car’s 8-speed automatic transmission performed intuitively, requiring no manual intervention for optimal performance.

In terms of braking and suspension, the Turbo E-Hybrid remained balanced and controlled, thanks to its new two-chamber air suspension system. Supply constraints on its carbon-ceramic brakes, however, may result in delivery delays, according to Porsche representative Calvin Kim.

While the vehicle’s added weight was noticeable during longer curves, it didn’t substantially hinder performance. Although the Turbo GT may offer a more dynamic track experience, the Turbo E-Hybrid provides a well-rounded package for daily driving.

Everyday Driving with the 2024 Cayenne Turbo E-Hybrid

In everyday conditions, the 2024 Cayenne Turbo E-Hybrid provides a harmonious blend of performance and practicality. Its default E-Power mode encourages electric-only driving, and while regenerative braking is always active, the transition between motor and friction braking remains mostly smooth.

Various drive modes offer different performance dynamics, and the vehicle’s new touchscreen interface enables customization of these modes along with suspension settings and exhaust system adjustments. Despite its sporty capabilities, the Turbo E-Hybrid maintains the luxurious appointments expected in a crossover SUV.

Final Thoughts

Priced at $151,400, the 2024 Porsche Cayenne Turbo E-Hybrid offers a more cost-effective yet equally compelling alternative to the Turbo GT. While it may not outperform its counterpart on the racetrack, its everyday driving capabilities are superior. Given impending advancements in electric vehicle technology, the Turbo GT’s days seem numbered, especially with the anticipated release of a fully electric fourth-generation Cayenne in 2026.

As Dr. Oerleke noted regarding the future of Porsche’s V-8 offerings, “It all depends on what the market wants.” In the rapidly evolving automotive landscape, Porsche has aligned its 2024 Cayenne Turbo E-Hybrid with both short-term market trends and long-term regulatory compliance. What remains uncertain is whether this balance will sustain Porsche’s V-8 offerings in the years to come.
