GWM H6 PHEV Review: Australian-Tuned Plug-In Hybrid SUV

content: Why the H6 PHEV Changes GWM's Australian Game

If you're considering a plug-in hybrid SUV in Australia, the GWM H6 PHEV demands attention for two breakthrough reasons. First, it brings electrified power to one of Australia's popular SUV segments just as emission regulations tighten. Second - and crucially - it's among the first Chinese models specifically engineered for Australian conditions. After analyzing extensive test footage from Victoria's former Holden Proving Ground, we confirm this isn't just marketing hype. The suspension and steering recalibration led by ex-Holden engineer Rob Tribiani transforms how this SUV handles our unique roads. But does it truly challenge established rivals? Our deep dive separates reality from promise.

Chapter 1: Australian Engineering Meets PHEV Power

The H6 PHEV represents a strategic pivot for GWM in Australia, combining local chassis development with advanced plug-in tech. Under the bonnet, a 1.5L turbo petrol engine pairs with electric motors delivering 240kW (FWD) or 268kW/760Nm (AWD). The 19kWh battery enables a lab-tested 100-106km electric range - though real-world results typically dip slightly.

What sets it apart is charging flexibility. Unlike most PHEVs, it accepts DC fast charging, enabling 30-80% top-ups at public stations. During real-world testing, the all-wheel-drive variant returned 4.6L/100km with mixed usage - significantly better than the 5.3L/100km official depleted-battery claim.

Crucially, the Australian-specific tuning includes revised dampers and steering calibration. Vehicles built from November 2025 onward feature this critical upgrade - earlier models lack these improvements. This isn't minor tweaking; it's a fundamental recalibration for our pockmarked roads and high-speed stability needs.

Chapter 2: Cabin Technology and Practicality Analysis

Step inside the Ultra-grade H6 PHEV ($45,990-$48,990 drive-away), and the tech upgrades immediately impress. Exclusive to this model is a faster 14.6-inch touchscreen with redesigned software and a new two-spoke steering wheel. While the interface resembles other Chinese brands, responsiveness is notably improved over standard H6 hybrids.

Key features demonstrate strong value:

• Wireless Apple CarPlay/Android Auto
• 10.5-inch digital instrument cluster
• Heated/ventilated power front seats
• Head-up display
• Premium interior materials with soft-touch dash

However, ergonomic challenges persist. Climate controls require screen navigation despite shortcut buttons, and the driver's seat lacks adjustable under-thigh support - a notable comfort limitation for taller drivers. Rear passengers enjoy generous knee-room (tested at 186cm height) but face a flat bench with minimal thigh support.

The 60/40 split-folding seats reveal a practical 584L boot, though the absence of a spare wheel (common among PHEVs) and shallow underfloor storage are compromises.

Chapter 3: Driving Dynamics and Real-World Performance

The Australian suspension tune transforms the H6 PHEV's road manners. On Victoria's challenging test routes, the revised damping demonstrated exceptional body control over crests and undulations. Steering calibration eliminates the dead zone prevalent in earlier GWM models, delivering sharper turn-in response.

The powertrain operates smoothly in daily driving, though moderate throttle input reveals slight lag before the electric torque surge engages. Regenerative braking proved linear and predictable - a notable achievement for PHEVs that often suffer grabby pedal feel.

Three critical observations emerged from dynamic testing:

1. Road noise remains pronounced at highway speeds despite acoustic improvements
2. KUMHO tires provide adequate but not exceptional cornering grip
3. Body roll is reduced but still evident during spirited driving

The seats proved a persistent weakness. The lack of thigh support becomes fatiguing on longer journeys, and the driving position feels slightly elevated despite height adjustment.

Your H6 PHEV Test Drive Checklist

1. Verify build date: Ensure the vehicle has November 2025+ compliance for Australian suspension
2. Test seat ergonomics: Spend 20+ minutes driving to assess thigh support
3. Evaluate charging: Use both AC and DC stations to check real-world charge times
4. Road noise test: Drive at 80-100km/h on coarse-chip surfaces
5. Suspension validation: Seek out potholed roads to assess damping control

The Verdict: A Calculated Step Forward

The H6 PHEV proves Chinese automakers can deliver competitive dynamics when investing in local tuning. The suspension and steering improvements are transformative, finally providing confidence on Australian roads. While the powertrain isn't class-leading, its DC charging capability and real-world 4.6L/100km efficiency make it a compelling option.

Compromises remain - particularly the seats and road noise - but at $48,990 drive-away for the AWD Ultra, it undercuts key rivals like the BYD Seal 6 ($49k+) while offering more standard features. For buyers prioritizing local tuning over brand prestige, this represents GWM's most convincing Australian offering yet.
