In depth: how these cars differ
This Across and GLB comparison brings together local model information and available derivatives for South Africa. Prices and specifications appear only where they have been recorded for this market.
Hagalu has withheld an overall score because at least one selected vehicle does not yet have four comparable categories and 50% weighted source coverage. Missing catalogue evidence is not replaced with a neutral score or a guessed value.
Use the key-spec and full-spec tables to compare the fields that are confirmed. For a purchase decision, verify current availability, exact derivative equipment, finance, insurance and ownership cover with the relevant manufacturer or authorised retailer.
Model imagery
Across and GLB image comparison
Open an image for its full canonical file or visit the model page for the complete vehicle record.
Hagalu does not turn missing specifications into neutral scores or guessed values.
Fail closed
Score withheld: fewer than four comparable categories or less than 50% weighted source coverage for at least one vehicle.
Use the verified key-spec and full-spec tables on this page. A ranked index will appear only after every selected vehicle has source-backed data in at least four categories and reaches 50% weighted coverage.
What the evidence means
No overall winner is declared because the selected vehicles do not yet meet Hagalu's minimum like-for-like source-coverage threshold. Compare the confirmed rows and verify the exact derivative before buying.
Related comparisons
Continue with closely related South Africa models and comparable body styles.
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.
