You’re shopping for a luxury electric SUV and your short list has two familiar badges: Cadillac Lyriq and Audi Q8 e-tron. Both promise quiet, effortless electric power, high-end cabins, and all-weather confidence. But once you dig into range, charging, and ownership costs, the differences start to matter, especially if you’re considering a used example.
Two similar missions, two very different roots
Overview: Cadillac Lyriq vs Audi Q8 e-tron
At a high level, the Lyriq plays the sleek, futuristic luxury cruiser with big range and strong DC fast-charging, while the Q8 e-tron leans into Audi’s traditional strengths: impeccable refinement, quattro all-wheel drive, and a familiar SUV feel. If you’re coming out of a gas Q7 or Escalade, both feel like natural next steps, just pointed firmly at an electric future.

Used EV shopping tip
Space, comfort, and design
Cadillac Lyriq: Concept-car drama
The Lyriq looks like Cadillac drove a concept car straight off an auto-show turntable and onto your street. The light show when you approach, the sharp body creases, and the long wheelbase all make it feel more like a design statement than a family hauler. Inside, a sweeping curved display and a simple dash layout push the tech front and center.
Front seats are generously cushioned, and the rear seat has excellent legroom thanks to that long wheelbase. The sloping roofline nips a bit of headroom for very tall passengers, but for most adults it’s comfortable and airy.
Audi Q8 e-tron: Classic luxury SUV
The Q8 e-tron is the more traditional SUV in this duo. From the outside, it’s instantly recognizable as an Audi: upright stance, tasteful details, and just enough chrome to look expensive without shouting about it. The cabin is quiet and meticulously finished, with physical switchgear mixed into the dual-screen center stack.
Seating is all-day comfortable, with slightly more upright chairs and excellent visibility. If you’re used to a Q7 or Q8, you’ll feel at home in about three minutes.
- Cargo space: Both offer generous two-row SUV practicality. The Lyriq’s rakish rear cuts a bit into maximum boxy space, while the Q8 e-tron’s squarer profile is easier for bulky items.
- Ride comfort: The Audi trends softer and more isolated, especially on air suspension. The Lyriq feels composed but a little more tied down, especially on larger wheels.
- Noise levels: Both are quiet; Audi still has a slight edge in road and wind noise suppression, especially at highway speeds.
Performance and driving feel
Performance highlights
On paper, these SUVs trade punches. In practice, they feel different from behind the wheel. The Q8 e-tron delivers ultra-smooth, almost understated acceleration: quick enough, but always polite. Steering is light but accurate, and with quattro AWD standard, it’s a confidence machine in bad weather.
The Lyriq, especially in dual-motor form, feels more playful. There’s more punch when you lean into the right pedal, and the chassis feels a bit livelier. Rear-drive Lyriqs serve up classic luxury-sedan vibes: quiet, composed, and effortless. If you care about driving fun, the Lyriq has the edge; if you want your EV to disappear into the background, the Audi will happily oblige.
Test-drive tip
Battery, range, and efficiency
Range is where the Cadillac Lyriq usually walks away from the Audi Q8 e-tron, especially in rear-wheel-drive trims. The Lyriq’s Ultium platform was designed from day one around big packs and efficient power electronics, and it shows in real-world miles.
Real-world range expectations
Your driving, climate, and wheel choice will move these numbers, but the trend line is clear.
Cadillac Lyriq range
- RWD models commonly rated around 300+ miles.
- AWD trims still often hover just above or near 300 miles.
- Owners report solid highway range when driven at U.S. speeds.
Audi Q8 e-tron range
- Updated battery boosted EPA range into the ~250–300 mile band depending on body style and wheel choice.
- Higher-speed highway driving can trim that more noticeably than in the Lyriq.
- Sportback body is typically the range champ within the Q8 family.
Cold weather and real-world results
Charging speed and road-trip readiness
Charging is more than a single headline kilowatt number. It’s about how quickly the battery actually adds miles, how long it can hold a strong charge rate, and whether the onboard AC charger fits your home situation.
Charging comparison: Cadillac Lyriq vs Audi Q8 e-tron
Approximate capabilities for recent model years; always verify for the exact vehicle.
| Charging aspect | Cadillac Lyriq | Audi Q8 e-tron |
|---|---|---|
| Max DC fast charge | Up to ~190 kW on compatible DC fast chargers | Up to ~170 kW on compatible DC fast chargers |
| 10–80% DC fast charge | Roughly ~30–40 minutes in ideal conditions | Around ~30 minutes claimed under ideal conditions |
| Onboard AC charger | Typically 11.5 kW or up to 19.2 kW on some trims | Commonly 9.6–19.2 kW depending on configuration |
| Home charging speed | Up to ~30–50+ miles of range/hour on a robust Level 2 setup | Typically ~20–35 miles of range/hour on Level 2 |
| Connector type (U.S.) | CCS1 (older models) transitioning toward NACS support with adapters over time | CCS1 (moving toward NACS via adapters as the industry standardizes) |
Both support DC fast charging and robust home charging, with Lyriq generally pulling ahead on road-trip speed.
Check your home electrical before you buy
Road-trip readiness checklist
Confirm real-world range
Look for owner reports, not just EPA stickers. If you regularly drive 250-mile days, the Lyriq’s extra cushion may keep your stops shorter and less frequent.
Study the charging curve
Both SUVs can hit impressive peak rates, but what matters is how they hold power from 10–80%. Reviews and owner logs will show whether the car tapers early.
Map your charging networks
Check where CCS fast chargers sit along your usual routes. Availability can matter more than 10–20 kW of theoretical peak power.
Plan home charging around your schedule
If you’re home every night, even a modest Level 2 setup is fine. If your schedule is unpredictable, the Lyriq’s higher onboard AC capacity can be a quiet advantage.
Tech, safety, and driver assistance
Both Cadillac and Audi have taken their best luxury tricks and poured them into these SUVs. You’ll find big digital displays, premium audio, and full suites of driver-assistance tech either standard or readily available.
Cadillac Lyriq technology
- Massive curved display that blends instrument cluster and infotainment.
- Google-based infotainment with built-in maps, voice assistance, and app integrations.
- Advanced driver-assistance options including hands-free highway driving on compatible roads (where equipped).
- Bold ambient lighting and dramatic exterior LED choreography when you approach or unlock the car.
Audi Q8 e-tron technology
- Dual MMI touchscreens plus a crisp Virtual Cockpit instrument display.
- Excellent haptics and mature navigation and audio controls, very familiar if you’ve owned a modern Audi.
- Comprehensive driver-assistance, including adaptive cruise, lane centering, and available 360° cameras.
- Subtle interior lighting and classic Audi design that ages gracefully.
Safety and confidence
Ownership costs and used EV value
Here’s where looking at used Cadillac Lyriq and used Audi Q8 e-tron can turn a luxury EV from aspirational to attainable. Luxury EVs have tended to depreciate faster than their gas counterparts, and both of these SUVs are now reaching the used market in meaningful numbers.
What to think about before you buy used
Battery health, warranty, and long-term costs matter more than 0–60 bragging rights.
Battery health
EVs don’t have oil changes, but the battery is everything. A healthy pack means reliable range and fewer surprises. Tools like the Recharged Score help you see verified battery health up front instead of guessing from a dashboard bar graph.
Warranty coverage
Both brands offer multi-year, multi‑mile battery warranties when new. On the used market, check how much coverage remains and whether it transfers fully to the next owner.
Total cost of ownership
Electricity is typically cheaper than gas, and maintenance is lighter. But tires for heavy luxury EVs are pricey, and insurance can run higher. A lower purchase price on a used Lyriq or Q8 e-tron can help offset those running costs.
Don’t ignore charging history
Which EV SUV fits you better?
Cadillac Lyriq vs Audi Q8 e-tron: pick your path
Choose the Cadillac Lyriq if…
Range and road-trip convenience are high on your list and you want as many real-world miles as you can get per charge.
You love dramatic design, inside and out, and want your EV to feel like a piece of modern tech, not just another SUV.
You value strong DC fast-charging and robust home charging options, especially with higher-capacity onboard chargers on some trims.
You’re open to rear-wheel drive for efficiency and driving feel, or you want the punch of a higher-output dual-motor setup.
Choose the Audi Q8 e-tron if…
You’re coming from a Q5, Q7, or Q8 and want everything you already like about Audi, just electrified.
Comfort, quiet, and traditional luxury matter more than outright range numbers on a spec sheet.
You live where weather gets messy and appreciate standard quattro AWD with predictable manners.
You prefer a more understated design that won’t shout “new EV owner” at the neighbors.
Still torn? Focus on your worst day, not your best.
