MotorTrend's review of the Aston Martin DBX 707 highlights it as one of the most thrilling performance SUVs on the market. The twin-turbocharged V-8, shared with AMG but hand-assembled by Aston Martin, delivers relentless thrust across the rev range. MotorTrend measured a 0-60 mph time of 3.1 seconds, placing it at the top of the segment alongside the Lamborghini Urus Performante. The nine-speed wet-clutch automatic shifts with immediacy in Sport+ mode, while the standard cast-iron brakes are robust, though carbon ceramics are optional. Inside, the cabin blends traditional British craftsmanship with modern technology, although the infotainment system is essentially a borrowed Mercedes-Benz unit that feels slightly outdated. MotorTrend criticizes the firm ride over broken pavement and notes that in Comfort mode, the suspension still transmits significant road imperfections. The steering is accurate but lacks the communication of smaller sports cars. Overall, MotorTrend concludes that the DBX 707 offers dramatic performance and head-turning styling, making it a strong alternative for those who find the Urus too common.

Autocar's comprehensive review of the Aston Martin DBX 707 positions it as the definitive performance SUV from the British marque. The review emphasizes that while the standard DBX was already competent, the 707 addresses the biggest criticisms — straight-line pace and transmission response — with the arrival of a nine-speed wet-clutch automatic and 697 horsepower. Autocar tested the 0-62 mph sprint in a claimed 3.3 seconds and praised the immediacy of the gearbox compared to the outgoing torque-converter unit. The ride and handling balance was characterized as "firm but controlled," with the air suspension and 48-volt active anti-roll technology keeping body movements in check during enthusiastic cornering. Autocar notes that the interior quality is exceptional, with a mix of leather, Alcantara, and metal that feels genuinely special. However, the review highlights that the infotainment system, sourced from Mercedes-Benz, feels dated and some switchgear lacks the tactility expected at this price point. As a whole, Autocar sees the DBX 707 as the most complete Aston Martin SUV to date — a compelling blend of performance, prestige, and practicality — though rivals like the Bentley Bentayga S offer superior ride comfort.
