Aston Martin has been testing a mild-hybrid version of its DBX crossover for several months, and the automaker has now revealed it as the DBX Straight-Six.
It's been developed exclusively for the Chinese market, and will make its formal debut at Auto Guangzhou 2021 which starts November 19.
The DBX Straight-Six features the same powertrain setup to the one used by Mercedes-Benz AMG for its current 53 series. The setup consists of 3.0-liter turbocharged inline-6 and beefed-up electric starter motor able to aid the engine during high loads and recover energy under braking. There's also an electric compressor to aid the turbo by building boost at low revs. Peak output is 429 hp and 384 lb-ft of torque.
Downsizing to a 3.0-liter engine has enabled Aston Martin to avoid punitive taxes that China levies on cars with big engines. The DBX Straight-Six starts at 1.898 million Chinese yuan (approximately $297,000), versus the 2.298 million Chinese yuan starting price of the regular DBX.
The new engine also marks a return to 6-cylinder engines at Aston Martin, with the last car to feature one, also an inline-6, being the DB7 of the 1990s.
2022 Aston Martin DBX Straight-Six (Chinese spec)
Production of the DBX only started in 2020 but the mid-size crossover already accounts for half of Aston Martin's sales. Understandably, the automaker is readying new variants to capitalize on the demand.
For the rest of the world, a high-performance DBX S model is due in 2022. Expect an uprated version of the 4.0-liter twin-turbocharged V-8 found in the current DBX. The V-8 delivers 542 hp in the current DBX but should have over 600 hp in the S version.
We know another version will be a plug-in hybrid. It should arrive around 2024, which is roughly when the DBX will be due to receive a mid-cycle update.
