Electric Defender Builds in 2025: What to Expect from Tesla-Powered Conversions
The classic Land Rover Defender is known for its rugged charm, military heritage, and go-anywhere utility. But in 2025, it's also becoming something else entirely — electric. From Hyper9 motor swaps to full Tesla drive unit conversions, EV Defender builds are redefining what’s possible with a vintage 4x4.
Whether you’re building a silent off-roader for weekend escapes or a zero-emissions city cruiser, electric Land Rover Defenders are the future of classic vehicle customization.
Why Convert a Defender to Electric?
Fuel prices are rising. Cities are tightening emissions laws. And EV performance is no longer just efficient — it’s exhilarating. A Tesla Defender build combines instant torque, zero-maintenance drivetrains, and sustainable power with all the iconic style of a vintage Defender 90 or 110.
EV conversions also reduce environmental impact while preserving the original vehicle’s body, frame, and presence on the road. Instead of replacing your classic 4x4, you’re reengineering it for modern life.
Tesla Defender Conversions: What’s Involved?
At Shoreline Vehicles, our electric Defender conversions often center around two systems: the Netgain Hyper9 and the Tesla Model 3 drive unit. Both offer unique advantages depending on how you plan to use your vehicle.
Tesla Model 3 Drive Unit
The most powerful option is a mid-mounted Tesla motor sourced from a Model 3. This delivers up to 300 horsepower, all-wheel drive, and 0–60 mph in about 5 seconds — faster than most modern SUVs.
The engine and gearbox are fully removed, replaced by a compact, efficient electric drivetrain. Power is routed directly to both axles, while the engine bay is repurposed for a custom battery pack, increasing capacity and range. With a large enough battery bank, you can expect up to 250–300 miles of real-world range.
Hyper9 Defender Builds
Prefer something simpler? The Hyper9 electric motor delivers around 120 hp and 260 Nm of torque, while keeping the original gearbox. It’s ideal for light use, urban driving, or lower-cost conversions. Range typically hovers around 100 miles, and it's a great option for Defender Series vehicles, early Defender 90s, or clients who want a modest electric upgrade with a lower budget.
What Do You Get with a Tesla Defender EV Conversion?
A Tesla Defender conversion isn’t just about the motor — it’s an end-to-end transformation that upgrades every system connected to the old internal combustion setup. Here’s what a full EV conversion includes:
High-voltage battery pack (mounted in place of engine and/or rear area)
Tesla drive unit (mid-mounted, connected to both axles)
Digital EV instrument cluster
DCDC converter to power 12V systems
Electric power steering system
Electric brake vacuum pump
High-voltage heater element for climate control
Charge port and onboard fast charging system
Upgraded wiring harness and battery management system
Regenerative braking setup
The end result is a fully electric Defender 90 or 110 that retains its rugged exterior and vintage charm — but drives like something from 2025.
What Does an EV Defender Build Cost?
EV conversions aren't cheap — but they’re getting more accessible. A full Tesla Defender build starts at around $150,000 and can climb depending on battery capacity, accessories, and finish level.
If you want something more affordable, Hyper9 builds are available in the $60,000–$85,000 range, depending on configuration. Shoreline offers phased build plans and full transparency on parts, labor, and options so you're never caught off guard.
