Aston Martin’s first SUV gets a cheaper Mercedes inline-six option, but it won’t be sold outside of China.
The 2022 Aston Martin DBX Straight-Six was unveiled – the first six-cylinder Aston Martin in two decades – though this second variant of the brand’s debut SUV will remain a Chinese market exclusive.
Joining the 4.0-liter V8 variant first presented in late 2019, the new six-cylinder DBX will only be sold in China, where buyers are taxed heavily for the purchase of cars with large engines – compounded if the vehicle is imported, as is the case with all Aston Martin Models.
Building on Aston Martin’s technical partnership with Mercedes-AMG, the DBX Straight-Six is powered by the German firm 3.0-liter turbocharged in-line six-cylinder petrol engine, developing 320kW Other 520 Nm – a match for AMG 53 models driven by the same engine.
It’s aided by a 48-volt mild-hybrid system with an integrated starter generator, capable of delivering electrified thrust under acceleration – up to 250Nm for up to three seconds – to “achieve a more efficient driving experience and luxurious, “according to Aston Martin China.
Traction is sent to all four wheels via a nine-speed automatic transmission, also supplied by Mercedes-AMG, which enables a 0-100km / h sprint of 5.4 seconds and a top speed of 259km / h – 0.9 seconds less than the speed limit. and 32 km / h slower at V-max, compared to the current V8 model (which cites 4.5 seconds and 291 km / h respectively).
Aston Martin China lists the Straight-Six’s combined fuel consumption as 10.5 liters per 100km, compared to 14.3 liters / 100km for the DBX V8. Interestingly, both figures are cited according to European WLTP tests, despite the fact that there are no plans to sell inline-six outside of China.
Under the skin, highlights include an electronic limited-slip rear differential (another Mercedes-AMG component), electronically controlled 48-volt anti-roll bars, a carbon fiber driveshaft, and three-chamber adaptive air suspension with 75 ground clearance adjustment (45mm up, 30mm down from the standard setting).
Alloy wheels measuring 21 to 23 inches in diameter fill the arches, hiding the 410mm front and 390mm rear cast-iron brakes, locked by front six-piston calipers and single-piston rear.
There’s little to divide the DBX Straight-Six from its eight-fold twin on the outside, with the only difference being the new “STRAIGHT-SIX” badges on the front side panels.
Inside, the six and eight-cylinder models share the same cabin, with a 10.25-inch central infotainment display, 12.3-inch digital instrument cluster and wireless smartphone charging, new for 2022.
The 2022 Aston Martin DBX Straight-Six is now available to order in China, priced at 1,898 million Chinese yuan ($ AU405,000) – a nearly 20% decrease from the V8’s list price of 2,298 million yuan ($ AU491,000) .
In Australia, the DBX V8 is priced at $ 356,512 before road costs – indicating a starting price of less than $ 300,000, the DBX Straight-Six is expected to arrive in Australia at a later date.
