Audi Q6 e-tron SQ6 e-tron vs Ford Mustang Mach-E Mach-E GT

The Ford Mustang Mach-E GT is the harder-accelerating car. Its dual motors produce 434kW and 955Nm, and it is 261kg lighter than the Audi at 2,276kg, a combination that Ford says is good for 3.7 seconds to 100km/h. The SQ6 e-tron answers with 360kW and a verified 4.4-second sprint, so the Mustang has both the power and the weight advantage in a straight line. MagneRide adaptive dampers and an Untame Plus mode add to the sense of occasion. In a straight line the Ford is decisively quicker.

In 2026 the SQ6 e-tron lists at $151,400 before on-road costs; the Mach-E GT drives away for $108,535. On any comparable basis the Audi costs far more, and it is the slower car. The premium buys completeness: standard air suspension, a 566km range against the Ford's 515km, a 526L boot that beats the Mustang's by 124L, a five-star ANCAP rating the GT lacks, and a plusher cabin. None of that is straight-line speed. If the quickest thrill for the money is the goal, the Ford is the answer.

The Audi SQ6 e-tron wins the practicality columns. Its boot holds 526L against the Mustang Mach-E GT's 402L, a 124-litre gap that upends the idea the premium car must be the less useful one. It also travels further, with 566km from its 100kWh battery against the Ford's 515km from 91kWh, and it sips a leaner 184Wh/km to the GT's 210. The Mach-E GT's coupe-inspired SUV shape looks the part but pays for it in cargo room. For carrying people and gear, the Audi is the clear pick.

The Audi SQ6 e-tron carries the Q6 e-tron's five-star ANCAP rating from 2024, which applies to every Q6 variant. The Ford is the exception in its own range: ANCAP's five-star rating for the Mustang Mach-E, based on 2021 testing, covers all variants except the GT, which it lists as unrated. The lesser Mach-E grades are five-star, but the GT specifically carries no star. Both cars fit the core active-safety suite, including autonomous emergency braking, lane keep assist and adaptive cruise. The clearer safety gap is the rating itself: the SQ6 has one, the Mach-E GT does not.

The two cabins chase different buyers. The SQ6 e-tron leans premium, with a triple-screen layout, a 14.5-inch central touchscreen and a head-up display, though reviewers flag some hard materials among the plush. The Mach-E GT counters with a single 15.5-inch portrait touchscreen, wireless smartphone mirroring, Ford Performance sport seats and Mustang-flavoured detailing that plays up the badge. Neither is short on technology. Buyers who want understated polish will prefer the SQ6; those who want the drama of the Mustang name inside as well as out will lean Ford.

This one is tighter than the price gap suggests. Both cars carry a five-year, unlimited-kilometre warranty, so there is no headline cover advantage either way. The Ford adds a year of roadside assistance, at seven years to the Audi's six, while the SQ6 answers with longer service intervals, at 30,000km or 24 months against the Ford's 15,000km or 12 months, so it visits the workshop half as often. Neither brand publishes a full five-year running-cost breakdown here. The Mach-E GT's much lower purchase price remains the larger ownership lever. On the paperwork it is close; the Ford's lower price is what actually moves the five-year total.

For a buyer chasing straight-line drama and the Mustang badge, the Mach-E GT is the obvious call. It brings 434kW and 955Nm, Ford's quoted 3.7-second sprint, MagneRide dampers and an Untame Plus mode built for the theatre, and it does it all for far less than the Audi. The trade-offs are the unrated safety status, the smaller boot and the shorter range, none of which matter much on a back road. We'd pick the Mach-E GT here for the enthusiast who wants noise, pace and presence over refinement, and who values the badge on the nose. The SQ6 is the more complete car, but completeness is not what this buyer is shopping for.

For the buyer who wants one EV to do everything well, the SQ6 e-tron is the stronger pick. It travels 566km between charges, carries 124L more luggage than the Ford, holds the only five-star ANCAP rating in the pair, and rides on standard adaptive air suspension the Mustang cannot match for compliance. Its cabin is the more restrained and luxurious, if less theatrical. We'd pick the SQ6 for the buyer who prizes space, refinement and safety over outright pace, and who can absorb the premium it commands. The Mach-E GT is the more exciting car in a straight line, but it asks real compromises the Audi does not.

For family duty, the SQ6 e-tron is the easier fit. Its 526L boot beats the Mach-E GT's 402L by a meaningful 124L, its 566km range means fewer stops on the school-holiday drive, and it carries the five-star ANCAP rating the GT is excluded from. Both seat five behind five doors, but the Audi's more conventional SUV shape gives up less head and cargo room than the Mustang's rakish roofline. We'd pick the SQ6 for the buyer whose car is a family hauler first and a performance toy second. The Mach-E GT can carry a family, but its shorter range and tighter boot make it the compromise choice for that job.
