2026 Defender 90 Powertrain and Performance: P400 vs. P525 V8

The 2026 Defender 90 P400 produces 395 hp and 406 lb-ft of torque from a 3.0L turbocharged mild-hybrid inline-6. The optional P525 V8 raises output to 518 hp and 461 lb-ft of torque, making it the most powerful Defender 90 model available. This page covers both powertrains in full, with current inventory at Land Rover Clear Lake in Friendswood.

Powertrain Overview

Two engines define the 2026 Defender 90 lineup, and each one sets a different intent for the vehicle. The P400 is the standard powertrain, a 3.0L turbocharged inline-6 with mild-hybrid assist that delivers 395 hp and 406 lb-ft of torque. The mild-hybrid system adds electrical assistance under acceleration and improves efficiency in mixed driving. The P525 is the performance model, using a 5.0L supercharged V8 producing 518 hp for clients who want increased output alongside the established off-road capability of Defender 90.

Both engines pair with an 8-speed automatic transmission and full-time all-wheel drive. A high/low transfer case is standard across both models, supporting controlled low-range driving in demanding conditions.

How the Powertrains Work

The P400 uses a turbocharged inline-6 and a 48-volt mild-hybrid system. The mild-hybrid component captures energy during deceleration and feeds it back to assist the engine under load, reducing strain at low speeds and improving throttle response in technical terrain. At highway speeds, the inline-6 configuration produces measured, linear power delivery well suited to long-distance travel across Texas.

The P525 V8 uses an intercooled supercharger, producing boost at virtually any engine speed. The result is immediate torque, with the V8 delivering its full 461 lb-ft across a wide RPM band. The P525 curb weight is 5,445 lbs, and the supercharged engine provides responsive performance in both on-road and off-road conditions.

Both engines send power through the same 8-speed automatic, which shifts cleanly and holds gears when the Terrain Response 2 system selects an off-road mode. The high/low transfer case allows the driver to select low range for controlled, high-torque crawling in demanding conditions.

Across the Models

The 2026 Defender 90 is offered in two models:

2026 Defender 90 P400 X-Dynamic SE

90 P400 X-Dynamic SE

The standard Ingenium inline-6 with mild-hybrid assist. This model includes the full Terrain Response 2 system, the 13.1-inch Pivi Pro infotainment touchscreen, ClearSight rearview mirror, Advanced Tow Assist, and the 360-degree surround camera. Towing capacity reaches 8,200 lbs. Ground clearance sits at 8.5 inches. The 48-volt mild-hybrid assist improves real-world fuel behavior without altering the driving character of a traditional combustion powertrain.

2026 Defender 90 P525 V8

90 P525 V8

The supercharged V8 carries the features of the P400 X-Dynamic SE and adds 123 horsepower for a total of 518 hp. For clients in Friendswood or across the broader Houston area who want stronger acceleration on both highways and trails, the V8 provides that additional output while retaining the standard capability equipment.

Real-World Benefit

For daily driving in Friendswood and the greater Houston metro, the P400 provides enough torque to merge confidently, tow a boat or trailer, and handle weekend trips to the Texas Hill Country. The mild-hybrid system is transparent to the driver. It operates in the background and requires no input.

The 8,200-lb towing capacity supports a loaded single-axle trailer, a midsize boat, or a utility trailer when the vehicle is properly equipped. That capacity is consistent across both powertrain options.

For clients who plan regular off-road use, the high/low transfer case and 8.5 inches of ground clearance combine with Terrain Response 2 to manage power delivery across changing surfaces. The system reads conditions and adjusts throttle mapping, transmission behavior, and traction parameters automatically. The broader torque reserve of the P525 V8 supports controlled response at low speeds.

The short two-door body of Defender 90 also reduces the turning radius relative to Defender 110, which matters when navigating tight trails or urban parking structures in Friendswood.

How It Compares

Clients comparing Defender 90 with vehicles such as the Mercedes-Benz G 450 and Jeep Wrangler 4xe will find different approaches to power delivery and electrification. The P400 combines a mild-hybrid inline-6 with an 8,200-lb towing rating, 8.5 inches of ground clearance, and a standard high/low transfer case.

The P525 V8 provides a less common combination of a supercharged engine and the short Defender 90 body. Its 518 hp output gives clients an alternative to the P400 without changing the core drivetrain and terrain systems.

The mild-hybrid assist in the P400 provides factory-integrated electrification without requiring external charging. This preserves a conventional ownership experience while adding electrical assistance during acceleration.
