2027 Cadillac OPTIQ Specs: Dimensions, Range and More
Here are the OPTIQ numbers shoppers search for most, with the Q4 e-tron alongside.
OPTIQ Dimensions vs. Q4 e-tron
| Dimension | 2027 Cadillac OPTIQ | 2026 Audi Q4 e-tron |
|---|---|---|
| Length | 189.8 in | 180.7 in |
| Width (with mirrors) | 84.0 in | 83.0 in |
| Height | 64.7 in | 64.7 in |
| Wheelbase | 116.0 in | 108.7 in |

| Front legroom | 41.6 in | 41.2 in |
| Curb weight | Varies by trim | 4,674 lb (RWD) / 4,850 lb (AWD) |
The OPTIQ is about 9 inches longer than the Q4 e-tron and rides on a wheelbase more than 7 inches longer, which shows up as more rear-seat and cargo room. Cadillac lists 37.8 inches of rear legroom. The Q4’s shorter body and tight 33.5-foot turning circle (RWD) make it a bit easier to park downtown.
OPTIQ Battery, Range and Efficiency
- Battery size: 85 kWh on every OPTIQ, compared with 82 kWh in the Q4 e-tron.
- EPA range: up to 317 miles with rear-wheel drive and 303 miles with all-wheel drive, versus 288 and 251 miles for the Q4 e-tron.
- Efficiency (AWD): 99 MPGe combined for the OPTIQ, versus 97 for the Q4 e-tron 55 quattro.
OPTIQ Horsepower and Drivetrain
The OPTIQ comes with rear-wheel drive and about 315 hp, or dual-motor all-wheel drive with up to 440 hp (Cadillac-estimated) (Carvana, Cadillac). The Q4 e-tron 45 makes 282 hp with rear-wheel drive and the 55 quattro makes 335 hp with all-wheel drive.
OPTIQ Towing and Cargo
The 2027 Cadillac OPTIQ offers a Cadillac-estimated towing capacity of up to 1,500 pounds on properly equipped models (GM Authority). Consult the vehicle’s owner’s manual and Cadillac’s towing guidelines for equipment requirements and limitations. Cargo space is about 26 cubic feet behind the rear seat and about 57 cubic feet with it folded, compared with 53.1 cubic feet maximum in the Q4 e-tron (Kelley Blue Book).
How do the OPTIQ and Q4 e-tron compare on price?
- Rear-wheel drive: the Q4 e-tron 45 Premium starts at $51,895, $800 less than the $52,695 OPTIQ Luxury RWD. The OPTIQ adds 29 miles of range, about 33 more horsepower and standard Super Cruise for that difference.
- All-wheel drive: the OPTIQ Luxury AWD starts at $56,195, $1,100 less than the $57,295 Q4 e-tron 55 quattro Premium, while making about 105 more horsepower and going 52 miles farther.
- Top of the range: the OPTIQ Premium Sport AWD tops out at $58,995, below the $61,795 Q4 e-tron 55 quattro Premium Plus.
Final pricing depends on incentives and options, so ask us for a written quote.
Which has more range?
The OPTIQ, by a clear margin. It is rated at up to 317 miles with rear-wheel drive and 303 miles with all-wheel drive (Cadillac). The Q4 e-tron is rated at 288 miles with rear-wheel drive and 251 miles with all-wheel drive (Kelley Blue Book). With all-wheel drive, which most Seattle-area buyers choose for winter trips, the OPTIQ goes about 52 miles farther.
Which charges faster?
The Q4 e-tron peaks at 175 kW on a DC fast charger and can go from 10 to 80% in about 28 minutes (The Charge Port). The OPTIQ peaks at 150 kW. The OPTIQ, however, has a native NACS port, so it plugs straight into compatible Tesla Superchargers, the largest fast-charging network in the country. When Audi launched its NACS adapter program in September 2025, the Q4 e-tron was not eligible (electrive), so ask an Audi dealer about current Supercharger access.
Super Cruise vs. Audi driver assistance: which offers hands-free driving?
- Cadillac Super Cruise is standard on every OPTIQ and allows hands-free driving on compatible highways, with an included plan (Cadillac Super Cruise). A paid plan is required after the included term.
- The Audi Q4 e-tron offers adaptive cruise control and lane-keeping assistance, but no hands-free driving system. The driver must keep their hands on the wheel.
If you spend a lot of time on I-405, I-90 or SR 520, a standard hands-free system is a meaningful everyday difference.
How do the interiors compare?
Both cabins are well made. The OPTIQ is built around a 33-inch curved display that spans the dash and a 19-speaker AKG Studio audio system with available Dolby Atmos. The Q4 e-tron pairs Audi’s virtual cockpit plus digital gauges with a center touchscreen and offers Sonos premium sound on Premium Plus trims. The OPTIQ’s longer wheelbase gives rear passengers more room, which matters if you carry adults or car seats regularly.
Which is quicker?
Audi quotes 5.0 seconds to 60 mph for the Q4 e-tron 55 quattro and 6.3 seconds for the 45. Cadillac doesn’t publish a 0-60 time for the OPTIQ, but the all-wheel-drive model’s 440 hp is about 105 more than the Q4 55 quattro’s 335 hp.
What about the warranty?
Both offer 4 years/50,000 miles of basic coverage and 8 years/100,000 miles on the EV battery. Confirm current terms for both at the time of purchase.
7 Reasons to Choose the Cadillac OPTIQ Over the Audi Q4 e-tron
01
More range
The OPTIQ is EPA-rated at up to 317 miles with rear-wheel drive and 303 miles with all-wheel drive. That is 29 and 52 miles more than the comparable Q4 e-tron, so fewer charging stops on trips to Snoqualmie, Leavenworth or Portland.
02
More power for less money
The OPTIQ Luxury AWD makes up to 440 hp (Cadillac-estimated) and starts $1,100 below the 335-hp Q4 e-tron 55 quattro. With all-wheel drive, you get more performance and more range while paying less.
03
Super Cruise hands-free driving
Cadillac’s Super Cruise allows attentive, hands-free driving on compatible roads, and it comes standard on every OPTIQ. The Q4 e-tron’s driver-assistance features require the driver to keep their hands on the wheel. Neither system makes the vehicle autonomous.
04
A 33-inch curved display
Cadillac’s 33-inch diagonal LED display integrates driver information and infotainment into one sweeping screen, giving the OPTIQ one of the most striking dashboards in the class.
05
More room inside
The OPTIQ is about 9 inches longer than the Q4 e-tron on a wheelbase more than 7 inches longer. That means more rear-seat space and up to about 57 cubic feet of cargo room, compared with 53.1 in the Audi.
06
Tesla Supercharger access built in
The OPTIQ has a native NACS charging port, so it plugs straight into compatible Tesla Superchargers as well as other DC fast chargers. When Audi launched its NACS adapter program in 2025, the Q4 e-tron was left out.
07
19-speaker AKG audio
Every OPTIQ comes with a 19-speaker AKG Studio audio system, with Dolby Atmos available. In the Q4 e-tron, Sonos premium audio requires stepping up to a Premium Plus trim.
Where the OPTIQ Wins:
- More range with RWD and AWD
- More horsepower, and a lower AWD starting price
- Standard hands-free Super Cruise
- 33-inch curved display and 19-speaker AKG audio
- Longer wheelbase and more cargo space
- Native NACS port for Tesla Supercharger access
Where the Q4 e-tron Wins:
- Slightly lower RWD starting price
- Faster peak DC charging: 175 kW
- Tighter turning circle, easier city parking
- Published 5.0-second 0-60 time (55 quattro)
- Higher efficiency rating with RWD (115 MPGe)
Which should you buy?
Pick the Cadillac OPTIQ if range, room, all-wheel-drive performance for the money and standard hands-free highway driving matter most. Pick the Audi Q4 e-tron if you want the lowest rear-wheel-drive price, slightly faster DC charging or a smaller footprint for city parking. The best way to decide is to drive them back to back on roads you know.
