The Aston Martin DBX represents the British marque’s bold entry into the luxury SUV market, combining signature sports car DNA with practical family functionality. Starting from $397,500 excluding on-road costs, the DBX positions itself firmly in the ultra-premium segment alongside competitors like the Bentley Bentayga and Lamborghini Urus.
Australian buyers face the additional burden of Luxury Car Tax (LCT), which applies at 33% on the value exceeding $80,567 for standard vehicles. Given the DBX’s pricing, this translates to substantial additional costs that buyers must factor into their purchase decision.
Engine Performance and Specifications
Power and Performance
The DBX is exclusively powered by a 4.0-litre twin-turbocharged V8 engine, delivering an impressive 520kW of power and 900Nm of torque. This Mercedes-AMG sourced unit propels the SUV from 0-100km/h in just 4.5 seconds, while maintaining the refined character expected from an Aston Martin.
Drivetrain and Handling
All variants feature sophisticated four-wheel drive, ensuring optimal traction across diverse driving conditions. The DBX incorporates adaptive air suspension and active anti-roll bars, delivering exceptional on-road dynamics while maintaining off-road capability.
Variants and Pricing Structure
| Variant | Price (Excl. On-Roads) | Power | Torque |
|---|---|---|---|

| DBX 707 | $439,000 | 520kW | 900Nm |
Fuel Economy and Running Costs
Efficiency Ratings
The DBX achieves a combined fuel consumption figure ranging between 12.4-14.2L/100km, depending on variant and driving conditions. While this places it outside the fuel-efficient vehicle category for LCT purposes, it remains competitive within its luxury SUV segment.
Service Requirements
Aston Martin recommends servicing intervals of 12 months or 16,000 kilometres, whichever occurs first. The comprehensive warranty package includes 2 years unlimited kilometre coverage, providing peace of mind for owners.
Luxury Car Tax Implications
Australian regulations require LCT payment on vehicles exceeding specific thresholds. For 2025, the standard LCT threshold is $80,567, with fuel-efficient vehicles qualifying for a higher $91,387 threshold. The DBX, consuming over 7L/100km, falls under the standard threshold, meaning buyers pay 33% tax on the amount exceeding $80,567.
Market Position and Competition
The DBX enters a highly competitive luxury SUV market, challenging established players through distinctive British design language and dynamic performance credentials. Its unique position combines Aston Martin’s racing heritage with practical everyday usability, appealing to discerning buyers seeking exclusivity and performance.
