Compact or Mid-Size Electric: Choosing Between the 2027 Cadillac Optiq and Lyriq

Cadillac builds two electric crossovers for everyday driving, and they sit at different sizes. The 2027 Optiq is the compact choice, 4,821 mm long on a 2,946 mm wheelbase. The 2027 Lyriq is the larger mid-size choice, stretching to 4,996 mm on a 3,094 mm wheelbase and carrying a 102 kWh battery.

Both seat five, both come with a 33-inch Horizon Display and both include Super Cruise as standard. This guide compares them on size, range, charging and trims so you can match the right one to your driveway and your routine.

At a Glance: 2027 Lyriq vs. Optiq

Size and Space

The Lyriq’s extra 175 mm of length and 148 mm of wheelbase give it a longer cabin and a more substantial presence. Behind the second row it holds 793 litres of cargo, and with the rear seats folded it reaches 1,722 litres. Its 178 mm of ground clearance also sits 26 mm higher than the Optiq’s.

The Optiq keeps a smaller footprint, which suits tighter parking and city streets. A 60/40 split-fold rear seat is standard, and the interior still seats five with 1,057 mm of front legroom and 960 mm of second-row legroom.

Range and Charging

Battery size drives the numbers. The Lyriq’s 102 kWh pack delivers 525 km with rear-wheel drive and 513 km with all-wheel drive. The Optiq’s 85 kWh pack delivers 510 km and 488 km. Both are strong figures for a crossover, and the Lyriq adds another 15 to 25 km on top of the Optiq’s.

• Both models include an 11.5 kW onboard charger as standard
• Optiq Premium trims include a 19.2 kW charger as standard, and it is optional on the Luxury and Sport trims
• Lyriq Premium and Signature trims offer the 19.2 kW charger as an option
• The Lyriq includes a Dual Level Charge Cord for 120V and 240V charging

Trims and Technology

The Optiq lineup runs from Luxury to Premium Sport, four trims in all. Every Optiq carries a 19-speaker AKG Studio audio system, a SkyGlass roof and Google built-in. The Lyriq lineup runs from Luxury to Signature Sport, six trims in all, and Premium and Signature trims move up to a 23-speaker AKG Studio system with Active Noise Cancellation, massage seats and a hands-free liftgate.

Winter comfort comes standard on both: heated front seats, a heated steering wheel and a heated wiper park. The Lyriq’s Signature trims add heated rear seats, and the Optiq’s Premium trims add them too, along with ventilated front seats.

Wheels and Styling

Both models ride on 265/50R20 tires, and each offers larger wheels as an option. The Optiq Luxury wears 20-inch Pearl Nickel wheels and the Optiq Sport wears 20-inch Dark Android wheels, with 21-inch Bronze or Gloss Black wheels available. The Lyriq Luxury wears 20-inch Split 6-Spoke wheels and the Lyriq Sport wears 20-inch Dynamic 12-Spoke wheels, while the Signature trims step up to 22-inch wheels as standard.

Which Cadillac Electric Is Right for You?

Choose the Lyriq when range, space and ground clearance lead your list. Its 102 kWh battery gives the longest range, its 3,094 mm wheelbase gives the roomier stance, and its six trims offer the widest choice of equipment, up to the Signature models.

Choose the Optiq when you want a Cadillac electric that fits easily into city life. Its 4,821 mm length is easier to park, its 510 km of range covers long weeks of driving, and its standard 19-speaker audio and Super Cruise put premium technology on every trim.
