Cadillac Lyriq Weight, Range & Specs: 2026 Review

2026 Cadillac Lyriq: Curb Weight, Range, and Real-World EV Data

If you've been searching for Cadillac Lyriq weight figures alongside the practical specs that actually matter in daily ownership, this profile covers the full picture. The Lyriq is Cadillac's flagship electric SUV built on GM's Ultium platform, and its mass directly shapes everything from efficiency and tire wear to braking feel and payload capacity. Below, we pair the curb-weight numbers with the range, charging, pricing, and tax-credit data buyers need before signing a lease or purchase agreement.

Why Cadillac Lyriq Weight Matters for EV Buyers

At approximately 5,560 pounds (RWD) and 5,760 pounds (AWD), the Lyriq sits squarely in the heavy-SUV category typical of 100+ kWh battery packs. That mass comes from the Ultium battery's nickel-manganese-cobalt (NMC) pouch cells, steel-intensive structural tray, and the Lyriq's premium sound-deadening and luxury appointments.

Here's what that weight means in practice:

• Tire wear: Expect 25,000–35,000 miles on OEM all-season tires — EVs in this weight class chew through rubber faster than ICE equivalents. Budget ~$1,200–$1,600 per set for 20-inch replacements.
• Braking: Regen handles most deceleration, but the Lyriq's mass means friction brakes engage more aggressively during panic stops. GM's brake-by-wire system is smooth, but stopping distances from 70 mph are slightly longer than lighter crossovers.
• Payload: With a GVWR around 6,330–6,530 lbs, subtracting curb weight leaves roughly 770–870 lbs of usable payload (passengers + cargo). That's adequate for four adults and luggage but tighter than some rivals.
• Efficiency trade-off: The Lyriq's 38–39 kWh/100 mi is reasonable for its class but trails lighter competitors like the BMW iX or Tesla Model X.

Real-World Range: EPA vs Highway vs Cold Weather

The Lyriq's 102 kWh usable NMC battery delivers solid city range thanks to regenerative braking recapturing energy from its heavy chassis. However, highway efficiency drops noticeably above 70 mph — the aerodynamic drag penalty on a 5,700-lb SUV is significant. In our cold-weather observation (Midwest, 20–30°F), range dipped roughly 20–25% versus the EPA sticker. The Lyriq does include a heat pump for 2025+ models, which mitigates cabin-heating energy draw, but battery chemistry still loses efficiency in sub-freezing temps.

For road-trip planning, budget 250 miles between DC fast-charger stops in ideal conditions and 200 miles in winter. The navigation system's route planner accounts for this automatically when you enter a destination.

Charging Speed: DC Fast, Level 2, and the Charge Curve

The Lyriq's 190 kW peak DC charge rate is adequate but not class-leading. Competitors on 800V architectures (Hyundai Ioniq 5, Kia EV6, Porsche Macan EV) hit 250–350 kW and complete 10–80% in 18–22 minutes. The Lyriq runs on GM's 400V Ultium system, which limits peak throughput.

Charge-curve reality: The 190 kW peak sustains roughly from 10–40% state of charge, then tapers to ~120 kW through 60%, and drops further to ~50–60 kW above 80%. That's why the 10–80% time is 33 minutes — the back half of the session is significantly slower. Preconditioning the battery (automatic when you navigate to a DC charger) is essential to hit these numbers in cool weather.

At home, the 11.5 kW onboard charger is a strong point. With a hardwired Level 2 wall connector on a 60A circuit, you'll recover a full day's driving in 1–2 hours overnight. Most Lyriq owners install a ChargePoint Home Flex or Emporia Vue charger; expect $800–$1,500 for equipment plus $500–$2,000 for electrician labor depending on panel proximity (source: typical 2025–2026 install quotes).

Pricing, Trims, and Federal Tax Credit Eligibility

*Federal §30D credit eligibility depends on buyer income, battery sourcing, and MSRP caps. The Lyriq's MSRP is under the $80,000 SUV cap. Verify current rules at irs.gov.

The Lyriq qualifies for up to $7,500 under the IRS §30D clean vehicle credit for eligible buyers, but the rules are layered:

• MSRP cap: The Lyriq is classified as an SUV, so the cap is $80,000. All current trims clear this.
• Income cap: Modified AGI must not exceed $150,000 (single), $225,000 (head of household), or $300,000 (joint).
• Battery sourcing: The $7,500 credit splits into two $3,750 halves — one for critical-minerals sourcing, one for battery-component assembly. GM has shifted significant Ultium cell production to US plants (Lansing, Spring Hill), but critical-mineral compliance fluctuates with supply-chain audits. Check the latest fueleconomy.gov tax credit listings before purchasing.
• Point-of-sale transfer: As of 2024+, you can transfer the credit to the dealer at purchase for an immediate price reduction rather than waiting for tax filing.

Interior Space, Tech, and Driver Assistance

The Lyriq seats five with generous front-row room (42.2 inches of legroom) and adequate rear space (39.6 inches legroom). Cargo volume is 28 cu ft behind the rear seats and 60.9 cu ft with seats folded — competitive with the BMW iX but slightly behind the Genesis Electrified GV70. Notably, the Lyriq has no front trunk (frunk); GM allocated that space to HVAC and power electronics.

Standout tech:

• 33-inch curved LED display (combines instrument cluster and infotainment into one glass panel)
• Google Built-In with native Google Maps, Assistant, and Play Store apps
• Super Cruise (Level 2 hands-free driving on 400,000+ miles of mapped highways — driver must remain attentive per SAE Level 2 requirements)
• AKG 19-speaker audio standard; optional 23-speaker system
• Available augmented-reality head-up display

Notable drawbacks:

• No frunk limits under-hood storage
• DC fast-charge speed trails 800V competitors
• Rear-seat headroom is tight for passengers over 6'2" due to the sloping roofline
• Infotainment learning curve — the massive screen replaces most physical buttons
