D-Max Extended Cab vs H6 GT PHEV questions

There is no universal winner. Use the comparison table to match the models and available derivatives in South Africa on price, safety equipment, space, powertrain and ownership cover. The category indicators summarise published catalogue data; they are not a road test or customer rating.

Compare the published consumption or mileage rows for the exact derivatives using the same unit and test basis. A catalogue figure is useful for like-for-like comparison, but traffic, speed, load, weather and driving style can change actual fuel use.

Compare only equipment explicitly listed for each derivative, including airbags, stability control and driver-assistance systems. Confirm the exact trim with the manufacturer, and treat any independent crash-test result separately because equipment and ratings can differ by market.

A reliable five-year total cannot be calculated from catalogue data alone. Add the exact purchase and finance cost, fuel or electricity, insurance quotes, scheduled servicing, tyres and expected resale value. Check whether the selected derivative includes a service or maintenance plan.

Use the seating, boot or load-space, ISOFIX and safety rows as a first check. Then test the exact cars with your child seats, passengers and typical luggage, because published dimensions do not show every access or comfort difference.

Compare the published power, torque and 0–100 km/h rows when they are available for both exact derivatives. Vehicle weight, gearing and power delivery also matter, so catalogue outputs alone do not establish real-world overtaking or response.
