For decades, Audi, BMW, and Mercedes-Benz have usually had competitors for most of their models, with a few exceptions like the Mercedes G-Wagen. But over the past few years, all three of these brands have had to slim down their lineups and made tough decisions about which models deserved to stick around and which, as fun as some of them may have been, had to die. These cuts have created gaps in each company's lineup, and, combined with different approaches to which EV segments they wanted to compete in first, have made each brand's portfolio more distinct from the others than ever before.Let's look closer at the models that Audi offers that BMW and Mercedes don't have competitors for, for better or worse. For this feature, we are only discussing 2026 model year offerings, and not counting potential competitors from the past or the future. We're also only looking at each brand's lineups in the United States and not including other vehicles offered elsewhere in the world. All listed starting prices include destination and freight charges. Audi RS3 Sedan 2025 Audi RS3 The Audi RS3 is one of the most fun vehicles Audi currently makes. The fact that it doesn't have a six-figure price tag and is a lot more attainable than any other RS model makes it even more lovable. That last-in-the-industry five-cylinder turbo engine certainly adds to the appeal, as does a laundry list of other things that make the RS3 awesome. We talked all about these great qualities in our review last year.Possibly because of how unbeatable it is, BMW has never bothered to make a 4-door subcompact that competes with it. The 2 Series Gran Coupe only goes as far as the M235i, which competes with the S3 instead. Some may view the two-door M2 as a competitor, as long as you won't miss the two extra doors, but it's not a direct competitor because of that omission.Mercedes used to have a competitor with the AMG CLA 45 S. It technically still does, with a 2026 model year, but the order books closed at the end of 2025, and it appears production has already concluded.There are fewer than 80 examples still listed to buy new in America. A new AMG is coming for the new-generation CLA, and our spies caught it last year. Based on its appearance, at least the first AMG version will be all-electric. Until that arrives, the RS3 has the high-performance subcompact four-door market to itself. Audi E-Tron GT 2026 Audi e-tron GT (5)The Audi E-Tron GT, as awesome as it is, lives in the shadow of its platform-mate, the Porsche Taycan. But thankfully, when it comes to competition from BMW and Mercedes, it doesn't have to worry about sharing the limelight. BMW has the less sporty i4 Gran Coupe, and Mercedes has the EQS Sedan, but neither of these is as low-slung or as high-performing as the E-Tron GT. The Audi now only comes as the S e-tron GT and the RS e-tron GT. The low seating position and the car's unique layout help the E-Tron GT drive unlike anything else on the EV market (other than the Taycan), and the high horsepower certainly helps (912 hp in the RS version!). It's clear that it benefits from the Porsche brilliance it inherited, which is hiding beneath the surface.While the newest iterations of the e-tron GT have come with nice enhancements, used GTs have the same great bones and are a screaming deal on the used market, with many nice examples for under $40,000. That's unbelievable for a car that started with a price tag past the six-figure mark just a few years prior. Even the bonkers RS version, which still had 637 hp and a stupid-fast 2.9-second 0-60 time, is only in the $50,000-$60,000 range, which is at least $30,000 less than a comparable Taycan Turbo, where you'd have to pay a hefty Porsche tax. How these have depreciated to such low prices is a mind-blowing mystery, but it's safe to say that it's one of the best used performance car bargains on the market today. Audi Q4 e-tron 2022 - 2026 Audi Q4 e-tron (18)The Audi Q4 E-Tron is an often-overlooked electric crossover that honestly should be more popular here, considering its lack of competition and good setup. Mercedes offers the EQB, so it's not completely devoid of competition. However, BMW has nothing to challenge it here in America, or any electric SUV, for that matter, other than the iX that's leaving the US after the 2026 model year.The upcoming iX3 takes aim at the larger Q6 E-Tron. BMW does offer the iX1 in Europe, but never decided to bring it here. The Q4 E-Tron is based on the Volkswagen ID.4 platform, but with the ID.4 making an exit from the US market, it won't even have to compete with its cheaper sibling soon.There's a decent amount of variety in the Q4 lineup, which should broaden its appeal, too. The Q4 is available in regular and sleeker Sportback body styles, along with a higher-horsepower all-wheel-drive version and a more affordable rear-wheel-drive version for those who don't see much bad weather. The SUV has attractive, unoffensive styling and a typical Audi interior that is pretty luxurious. It's also well-priced, starting at just $51,895.And yet, Audi only sold 6,738 of the regular and Sportback variants combined in 2025, when EVs were in higher demand. It's possible it was supply-limited, since they were imported from Germany amid the 2025 tariff whiplash. Still, even with that factored in, it shows that, even with minimal competition and a solid offering, some vehicles still might not succeed everywhere. In Europe, the Q4 E-Tron is consistently one of the strongest-selling EVs in its class, so this lack of love for the Q4 E-Tron is strictly an American sentiment. BMW And Mercedes Also Have Models With No Audi Competitor Mercedes We'd be remiss if we didn't mention that BMW and Mercedes also have models that Audi has no direct competitors for. In addition to the G-Class, Mercedes still has a two-door coupe and convertible with the CLE, a segment Audi gave up with the last-generation A5. Mercedes has also continued with sports cars on the upper end, with the SL and the AMG GT 2-Door, which no longer have the R8 to compete with. On the electric side, there's also the CLA EV, and the full-size EQS Sedan and EQS SUV, not to mention all the plug-in hybrids they still offer. Audi will soon rejoin the fray with a fresh crop of new plug-in hybrids beginning with the next-gen RS5, but in the meantime, anyone looking for a PHEV Audi will need to go to the used market.On the BMW side, Audi can't match the coupes and convertibles again. In this case, the 2 Series and 4 Series. And while Audi's A6 e-tron competes with the i5, BMW also has the i4 and the i7, plus the new i3 coming, with no Audis coming to compete with those in the near future. Lastly, BMW has the X2 for those who want a sportier X1. Audi tries to cover both buyers with the less boxy but still practical Q3. So, as you can see, these days each brand has different strengths and weaknesses in its lineup, and its offerings are more diverse than ever before.Sources: Audi, BMW, Mercedes-Benz
