Cadillac Optiq Luxury (2026) vs Audi Q4 e-tron Premium Plus (2025): Compact Luxury EV Review
Two luxury badges, two very different answers to the same question. The 2026 Cadillac Optiq Luxury and the 2025 Audi Q4 e-tron Premium Plus are both compact electric SUVs priced in the fifties, both aimed at buyers who want a premium badge without a flagship-sized payment. Yet they disagree on nearly everything that matters: how much power you get, how far you can go, how fast you can recharge, and what the cabin feels like on a winter drive across Ohio.
One honest note before we start: "Premium Plus" is a trim, not a powertrain, and Audi sells it two ways. This comparison uses the all-wheel-drive Q4 55 e-tron Premium Plus quattro — 335 horsepower, 258 miles of EPA range — against the all-wheel-drive Optiq Luxury, which for 2026 makes 440 horsepower and travels 303 miles. The rear-wheel-drive versions of both cars get their own mention in the pricing section.
The early verdict: the Cadillac wins on power, range, and price — and it is not particularly close on any of the three. But the Audi wins on charging speed, on the polish of its cabin tech, and on the simple fact that it feels like an Audi inside. If you charge at home and want the most electric SUV for the money, take the Optiq. If you road-trip often and value a faster pit stop, the Q4 earns a long look.
Quick Verdict
- Power: Cadillac Optiq Luxury AWD — 440 hp and 498 lb-ft vs the Audi's 335 hp and 339 lb-ft. A 105-horsepower gap.
- Range: Cadillac — 303 miles EPA (AWD) vs the Audi's 258. The rear-drive Optiq stretches that to 317 miles.
- Charging speed: Audi — 175 kW peak and about 28 minutes from 10 to 80 percent, against the Cadillac's 150 kW peak and an estimated 40 minutes.
- Cargo: Cadillac — 26.0 cubic feet behind the rear seats vs 24.8 in the Audi; 57.0 vs 53.1 with the seats folded.
- Cabin tech: Audi — wireless Apple CarPlay and Android Auto, plus a more conventional, easier-to-learn layout.
- Driver assistance: Cadillac — Super Cruise hands-free driving comes standard on every Optiq.
- Value: Cadillac — $53,495 before destination for the AWD Luxury, against $59,000 for the Audi. That is a $5,505 gap before you add anything.
- Best for Ohio winters: Tied on traction — both are dual-motor all-wheel drive — but the Cadillac's longer range and heat pump give it the edge on cold mornings.

Design & Exterior
The Optiq looks like a Cadillac that went to finishing school. The illuminated black-crystal grille, the vertical LED light signatures, and the Galvano chrome detailing are all unmistakably from the same design family as the Escalade IQ, just shrunk to a size that fits a suburban driveway. At 189.8 inches long on a 116.3-inch wheelbase, it is a full nine inches longer than the Audi, and the proportions show it: a long hood line, a low roof, and 20-inch Pearl Nickel wheels that fill the arches without looking like an afterthought. It reads as the bigger, more expensive car, which is a neat trick for the cheaper one.
The Q4 e-tron takes the opposite approach. Audi's design language here is restrained to the point of quiet — clean surfacing, a closed-off Singleframe grille, and proportions that owe more to a tall hatchback than a traditional SUV. At 180.7 inches, it is the easier of the two to park and the easier to thread through a crowded Columbus garage. Where the Cadillac wants to be noticed, the Audi is content to be recognized by people who already know what they are looking at.
Both cars get LED lighting, power liftgates, and panoramic glass roofs as standard equipment on these trims — the Optiq's fixed SkyGlass roof with a power shade, the Audi's panoramic sunroof. The Cadillac adds illuminated power-extending door handles, a small piece of theater the Audi answers with nothing at all. Neither car will embarrass you in a valet line, but if road presence is part of the purchase, the Optiq carries the moment. If understatement is, the Q4 does.
Interior, Comfort & Technology
Step inside the Optiq and the first thing you notice is the screen: a single 33-inch curved display that runs across the dashboard, housing the instruments and the infotainment in one sweeping panel. It runs Google built-in software, which means Google Maps and Google Assistant are native — but it also means there is no Apple CarPlay and no Android Auto at all, and for some buyers that is a deal-breaker worth discovering before the paperwork, not after. The cabin itself is quiet and well finished, with leatherette upholstery, heated front seats and a heated steering wheel, and a 19-speaker AKG Studio audio system with Dolby Atmos that is genuinely excellent.
The Audi answers with a cabin that feels less like a technology demonstration and more like a car you already know how to use. A 10.25-inch Digital Cockpit Plus sits ahead of the driver and an 11.6-inch MMI touchscreen handles the rest, with wireless Apple CarPlay and Android Auto standard — the phone integration the Cadillac refuses to offer. Premium Plus adds a Sonos premium audio system, a heated steering wheel, dual power front seats, a wireless charging pad, and a power liftgate, on top of standard leather seats, heated front seats, and tri-zone climate control.
The honest split is this: the Cadillac gives you more screen, more sound, and more space for less money. The Audi gives you a cabin that works the way you expect it to, with your phone in the middle of it. Buyers who live in Google's world will be happy in the Optiq. Buyers who live in their iPhone will be happier in the Q4.
Performance & Driving Feel
On paper, the performance gap is the widest in this comparison. The Optiq Luxury AWD makes 440 horsepower and 498 lb-ft of torque from its dual motors, and MotorTrend estimates it will reach 60 mph in under five seconds. The Q4 55 quattro makes 335 horsepower and 339 lb-ft, and Audi claims 5.0 seconds — MotorTrend actually tested one at 4.7. In the real world, the Audi is quicker than its spec sheet suggests and the Cadillac is quicker than the Audi, full stop.
What matters more is how they deliver it. The Optiq's power arrives with the calm, linear surge of a big GM electric motor, and the single-speed transmission means there is never a shift to interrupt it. One-pedal driving with two intensity settings is standard, and the heat pump — standard on the Cadillac — helps preserve range when the temperature drops below freezing, which in Ohio is roughly half the year. The Audi's dual motors feel a touch more eager at low speed, and its quattro system has decades of tuning behind it.
Neither car pretends to be a sports car, and that is fine. Both are quiet, composed, and quick enough to merge onto I-70 without thinking about it. The Cadillac's advantage is the one you feel every time you press the accelerator; the Audi's advantage is the one you feel every time you forget you are driving an electric car at all.
Range & Charging
This is where the comparison tilts hard in the Cadillac's favor — and then tilts back. The Optiq Luxury AWD carries an 85-kWh usable battery and an EPA rating of 303 miles. Choose the standard rear-wheel-drive version and the same battery stretches to 317 miles. The Q4 55 quattro carries 77 kWh usable and an EPA rating of 258 miles. That is a 45-mile gap in the Cadillac's favor in all-wheel-drive form. For a Columbus-to-Cleveland round trip in January, that gap is the difference between charging and not charging.
But the Audi claws much of it back at the charger. The Q4 55 peaks at 175 kW on a DC fast charger and goes from 10 to 80 percent in about 28 minutes, according to Audi. The Optiq peaks at 150 kW, and Cadillac does not publish a 10-to-80-percent time at all; independent estimates put it around 40 minutes. On a road trip, the Audi's shorter stops partly offset its shorter range. At home, the difference mostly disappears: the Cadillac's standard 11.5-kW onboard charger fills the battery in about nine and a half hours on a 240-volt circuit, with a 19.2-kW charger available as an option; the Audi's 11-kW onboard charger needs roughly twelve hours.
One more 2026 change matters for real-world charging: the Optiq now comes with a native NACS port, the Tesla-style connector, which means direct access to Tesla Superchargers without an adapter. For an Ohio buyer, that is a genuine practical advantage on long trips, because Supercharger coverage along I-71 and I-75 is still denser than CCS coverage in many stretches. Neither car qualifies for a federal tax credit anymore — the credit has expired for the Optiq, and the Q4 is built in Zwickau, Germany, so it never qualified — which means the sticker price is the price, and the Cadillac's $5,505 advantage is real money.
Safety & Driver Assistance
The Optiq's headline safety feature is Super Cruise, and it comes standard on every Optiq, including the base Luxury. Hands-free driving on compatible highways is the single most impressive piece of driver assistance either car offers, and on the long, straight stretches of Ohio interstate it genuinely changes the drive. Around it, Cadillac bundles front and rear automatic emergency braking, intersection collision avoidance, blind-spot monitoring, lane-keep assist, adaptive cruise control, and a surround-view camera, all standard.
The Audi counters with its own complete suite: Audi pre sense, adaptive cruise control, blind-spot and lane-departure warning, lane-keep assist, and rear cross-traffic alert. One thing to know before you buy: the 360-degree camera is a $500 option on the 2025 Premium Plus, not standard equipment, and matrix-design LED headlights are a Prestige-trim feature. The Q4 also carries a blemish worth mentioning: the IIHS rated it Poor in its updated moderate-overlap front crash test. Neither car is unsafe, but the Optiq's standard Super Cruise and cleaner safety story give it the edge here.
Pricing, Trims & Value
The numbers are simple, and they favor the Cadillac. The 2026 Optiq Luxury with all-wheel drive starts at $53,495 before a $1,495 destination charge, for a total of $54,990. The 2025 Q4 55 e-tron Premium Plus quattro starts at $59,000 before a $1,295 destination charge, for a total of $60,295. That is a $5,305 difference at the door, for a car with more power, more range, and more cargo space.
The rear-wheel-drive versions widen the story further. The Optiq Luxury RWD starts at $49,995 plus destination — $51,490 all in — with 315 horsepower and 317 miles of range. The rear-drive Q4 45 Premium Plus starts at $53,600 plus destination — $54,895 all in — with 282 horsepower and 288 miles of range. Whichever way you configure them, the Cadillac is cheaper and goes farther.
Both cars carry an 8-year, 100,000-mile battery warranty, and Cadillac adds a 4-year, 50,000-mile basic warranty with a year of free maintenance. Residual values are a guess for both — the Optiq is a second-year model in a fast-moving segment — but the lower purchase price means the Cadillac has less value to lose.

Who Should Buy Which?
Buy the Cadillac Optiq Luxury if you charge at home most nights, want the longest range and the most power for the money, and drive the Ohio interstate system often enough for Super Cruise to matter. It is the rational pick on nearly every measurable count, and the rear-wheel-drive version at $49,995 is the value play of the compact luxury EV class right now — 317 miles, 315 horsepower, and a NACS port for $51,490 at the door.
Buy the Audi Q4 e-tron Premium Plus if you road-trip regularly and value the fastest possible charging stop, if your phone is an iPhone and CarPlay is non-negotiable, or if you simply want the car that feels most like a traditional luxury SUV inside. The Audi asks you to pay more for less range and less power, and the only honest way to justify that is to admit that the cabin, the charging curve, and the badge matter to you. For plenty of buyers, they do.
If you are torn, the tiebreaker is simple: test-drive both on the same day, back to back, and spend ten minutes in each car pairing your phone. If the Optiq's Google-only system bothers you, the Audi has already won. If it does not, the Cadillac's range, power, and price are very hard to walk away from.
Final Verdict
The 2026 Cadillac Optiq Luxury is the better compact luxury EV in this comparison, and the margin is wider than the price gap suggests. It is more powerful, it goes farther on a charge, it carries more cargo, it comes with Super Cruise standard, and it costs $5,305 less than the Audi at the door. The 2026 updates — the stronger all-wheel-drive system, the longer range, the lower base price, and the native NACS port — turned a car that was already competitive into the value leader of its class.
The Audi Q4 e-tron Premium Plus is not a loser; it is a different kind of winner. It charges faster, its cabin is easier to love on day one, and it keeps the phone integration that millions of buyers consider mandatory. If those things top your list, buy the Audi and enjoy it — the 28-minute charging stop is a real, everyday advantage on a road trip.
But for most Ohio buyers, the one we would take home is the Cadillac. The range advantage covers the Audi's charging advantage on all but the longest trips, the power advantage is there every time you touch the accelerator, and the price advantage is there every month when the payment comes due.
FAQ
Which has more range, the 2026 Cadillac Optiq Luxury or the 2025 Audi Q4 e-tron Premium Plus?
The Cadillac. The all-wheel-drive Optiq Luxury is EPA-rated at 303 miles, and the rear-wheel-drive version at 317 miles. The all-wheel-drive Q4 55 Premium Plus quattro is rated at 258 miles. The rear-drive Q4 45 Premium Plus does better at 288 miles, but it still trails both Optiq configurations.
Which charges faster?
The Audi. The Q4 55 quattro peaks at 175 kW on a DC fast charger and goes from 10 to 80 percent in about 28 minutes. The Optiq peaks at 150 kW, and Cadillac does not publish a 10-to-80-percent time; independent estimates put it around 40 minutes. The Optiq counters with a native NACS port for direct Tesla Supercharger access.
How much does each cost?
The 2026 Optiq Luxury AWD starts at $53,495 plus a $1,495 destination charge ($54,990 total). The 2025 Q4 55 Premium Plus quattro starts at $59,000 plus a $1,295 destination charge ($60,295 total). The rear-wheel-drive Optiq Luxury is $49,995 plus destination, and the rear-drive Q4 45 Premium Plus is $53,600 plus destination. Neither qualifies for a federal EV tax credit.
Does the Cadillac Optiq have Apple CarPlay?
No. The Optiq runs Google built-in software and does not offer Apple CarPlay or Android Auto on any trim. The Audi Q4 e-tron offers wireless Apple CarPlay and Android Auto as standard equipment, which is one of its strongest advantages over the Cadillac.
Is the Audi Q4 e-tron Premium Plus all-wheel drive?
It depends on the powertrain. Premium Plus is a trim level offered on both the rear-wheel-drive Q4 45 (282 hp, 288 miles) and the all-wheel-drive Q4 55 quattro (335 hp, 258 miles). This comparison uses the Q4 55 quattro, the all-wheel-drive version, against the all-wheel-drive Optiq Luxury.
