The Aston Martin DBX GT has joined the British marque’s SUV line-up as a more luxury-oriented derivative alongside the more overtly sporty DBX S, with exterior styling and interior appointments to reflect the brand new chassis setup geared toward providing more compliance without losing driver engagement.
Said to deliver “the final word in luxury and refinement” from the marque, the DBX GT wears a visually restrained exterior relative to the DBX S, somewhat alike the approach taken by rival marque Bentley with the Bentayga S and Mulliner variants.
Headline figures from its 4.0 litre biturbo V8 petrol engine are unchanged from the DBX S, with 727 PS and 900 Nm sent to all 4 wheels through the nine-speed automatic transmission, enabling the identical 0-96 km/h time of three.1 seconds while top speed is 309 km/h.
Braking hardware is similar as that of the DBX S, with carbon-ceramic units featuring 420 mm discs in front and 390 mm discs on the rear. Its steering ratio can be shared with the DBX S, and provides a turning circle of 12 metres, says Aston Martin.
Where the refinement-oriented changes come are within the revised calibration of the dampers, including a damper valve system unique to the DBX GT for improved ride compliance over poor surfaces while body control is maintained during dynamic driving.
The brand new suspension damper valving is geared toward higher managing oil flow during high frequency, low amplitude inputs comparable to on rough road surfaces or rumble strips, and to scale back vibrations transmitted into the cabin.
Spring rates change depending on the drive mode chosen, while two recent longitudinal dampers help to administer the connection between the body and rear subframe for a greater feel of structural integrity during suspension inputs comparable to large potholes, sharp crests and severe compressions, says Aston Martin.
Further improvement in low-speed ride refinement and compliance comes from standard-fit 22-inch wheels, though 23-inch rollers – shod in summer or all-season tyres – proceed to be available to specify.
Also revised for improved refinement is the calibration of the nine-speed automatic transmission, geared toward delivering higher consistency from relaxed, low-speed urban driving to full-throttle applications. A brand new transmission mounting bush increases mounting stiffness for higher management of transmission movement relative to the vehicle body.
The theme of improved refinement continues with a dedicated exhaust tune, says the manufacturer; double-mixing of gas flow throughout the rear exhaust muffler makes for a cleaner, richer tone by reducing the harsher, metallic frequencies. A specially tuned GT mode goals to be discreet, while Sport and Sport + modes restores the complete exhaust tone of the DBX GT.
Inside, the DBX GT gets redesigned front and rear seats with revised cushioning, bolstering and reengineered comfort curves that aim to balance support during dynamic driving and on a regular basis usability, says the marque.
The rear seats have what Aston Martin calls an “individual” seat layout, which actually retains five seats but places more concentrate on styling and luxury of the 2 outer seats.
These have been styled to more closely align the outer rear seats with the front seats, with prolonged headrests and bolsters geared toward providing greater comfort for longer journeys, while a panoramic glass roof is standard on the DBX GT for added natural light.
Interior appointments for the DBX GT are geared toward making a fair more luxurious interior, where an anodised metal drive mode rotary controller and secondary switchgear offer a “jewellery quality finish”, says Aston Martin.
Upholstery configurations are offered in monotone, duo-tone and tri-tone mixtures, while embroidery stitching is obtainable in a pattern unique to the DBX GT. Semi-aniline leather is used; each front seat alone within the DBX GT requires 691 m of thread, 3,297 perforation holes and greater than 4.5 hours of workmanship, noted the marque.
Further refinement improvements come from greater attention to cabin sealing, placement of sound-deadening material within the door panels, front and rear wheel arch zones and luggage compartment, in addition to the usage of acoustic laminated rear side glass.
Deep pile carpets serve not only so as to add to the posh feel, but additionally to support acoustic isolation. Aston Martin claims a measurable improvement of 13% within the articulation index, referring to how easy it’s to carry a conversation in a moving vehicle.
Deliveries of the Aston Martin DBX GT are scheduled to start out within the fourth quarter of this 12 months.
