Cadillac has always stood for refined luxury, but fuel efficiency has become just as vital to today’s buyers as leather seats and premium audio. Whether you’re running the daily stretch between Gulfport and Biloxi or cruising a long haul on I-10, knowing where each model lands on the fuel economy scale helps you make a smarter call.
Here’s a full lineup breakdown to help you find the most efficient Cadillac for your specific situation. Browse our new Cadillac inventory to see what’s currently in stock in Gulfport.
Cadillac MPG Rankings: Which Model Leads in Fuel Efficiency?
Across the current lineup, sedans consistently rank highest for fuel economy. The CT4 leads all gas-powered models in highway mileage, with the CT5 following close behind and offering a solid balance between performance and efficiency. On the SUV side, the XT4 stands out as the most fuel-efficient crossover, while the larger XT5, XT6, and Escalade give up some MPG for added space and capability.
Drivers who want maximum efficiency will find Cadillac’s growing EV lineup operates on a different scale entirely, with MPGe ratings and driving range replacing traditional fuel economy figures.
Gas-Powered Cadillac MPG Rankings at a Glance
The CT4 and CT5 sedans top the efficiency list, followed by the compact XT4, the midsize XT5, and then the three-row XT6 and full-size Escalade toward the lower end of the spectrum. One thing worth factoring in early: choosing AWD over FWD or RWD typically costs 1-2 MPG combined across most models.

Cadillac Sedan Fuel Economy: CT4 and CT5 Lineup Breakdown
If you’re a fuel-conscious buyer, Cadillac’s sedan lineup is where things get interesting. Both the CT4 and CT5 pair genuinely luxurious interiors with strong MPG figures, making them compelling for drivers who log serious highway miles.
CT4 MPG: A Final-Year Leader Worth Knowing
The CT4 earns its spot at the top of the efficiency rankings with a 2.0L turbo four-cylinder producing 237 hp and 258 lb-ft of torque. In RWD trim, it returns 21 city / 31 highway / 25 combined MPG. The 17-gallon fuel tank pushes highway range past 500 miles on a single fill, which is genuinely practical for Gulf Coast road trips.
One key shopping note: 2026 is the final model year for the CT4. Final-year models are still available and represent strong value for efficiency-focused buyers who want a compact, driver-oriented luxury sedan before the nameplate wraps up.
CT5 and CT5-V MPG: Luxury Performance Meets Efficiency
The CT5 steps up in size while matching the CT4 at 26 combined MPG in RWD form (23 city / 33 highway), and it actually edges ahead on highway with the same 2.0L turbo engine. More interior space with no efficiency penalty makes the CT5 an easy recommendation for buyers who want room without paying more at the pump.
The CT5-V and CT5-V Blackwing represent a deliberate performance trade-off, which is worth understanding clearly. The CT5-V’s 3.0L twin-turbo V6 delivers 360 hp at 21 combined MPG in RWD trim. The CT5-V Blackwing’s 668 hp supercharged V8 drops to 15 combined (13 city / 20 highway). Those numbers reflect the real cost of serious performance hardware.
Cadillac SUV MPG: XT4, XT5, XT6, and Escalade Breakdown
Cadillac SUV fuel economy follows a predictable pattern: size and capability come at an efficiency cost. That said, the XT family crossovers are genuinely competitive within the luxury SUV segment, and engine choice within each model makes a significant difference.
XT4 and XT5 MPG: Compact and Midsize Efficiency Leaders
The XT4 is the clear efficiency leader in Cadillac’s SUV lineup. With the 2.0L turbo and FWD, it returns 23 city / 30 highway / 26 combined MPG, matching the CT4’s combined figure in a crossover body. Its 15.9-gallon tank delivers roughly 477 miles of highway range in FWD trim. Opting for AWD brings that to 22 city / 29 highway / 25 combined, a modest one-MPG penalty that most buyers will consider worthwhile for added traction.
The XT5 moves into midsize territory with a more spacious interior and better rear cargo room. The 2.0L turbo FWD returns 22 city / 29 highway / 25 combined, while the 3.6L V6 drops to 21 combined regardless of drivetrain. That three-to-four MPG combined penalty for the V6 is worth weighing carefully if efficiency is a priority.

XT6 and Escalade MPG: Three-Row and Full-Size Realities
The XT6 adds a third row over the XT5 but carries additional weight, and it shows in the numbers. The 2.0L turbo returns 23 combined (FWD or AWD), while the 3.6L V6 drops to 21 combined FWD and 20 combined AWD. For families who need that third row without stepping up to a full-size vehicle, the 2.0L turbo XT6 is the sensible engine choice.
The Escalade and Escalade ESV are honest about what they are: V8 flagships built for maximum presence, capability, and interior space. The Escalade’s 6.2L V8 returns 17 combined in RWD and 16 combined in 4WD, while the Escalade ESV runs 16 combined RWD and 15 combined 4WD.
When properly equipped, the Escalade tows up to 8,100 lbs (RWD) and the Escalade ESV up to 8,000 lbs (RWD), with the standard Escalade carrying a 24-gallon fuel tank and the longer ESV stepping up to a 28-gallon tank for extended range between stops. The Escalade-V and Escalade ESV-V, with their supercharged V8s, come in at 13 combined MPG. These trims are purpose-built for performance, not economy, and that’s exactly the point.
Cadillac EVs: MPGe, Range, and Efficiency Explained
Electric Cadillacs operate on a different efficiency scale entirely. Instead of miles per gallon, EVs use MPGe (miles per gallon equivalent), which translates electric energy consumption into a familiar framework. Higher MPGe means less energy used per mile, which directly lowers your operating costs. Range per full charge is the other number to keep in focus.
| Model | Type | EPA Range | Combined MPGe |
| LYRIQ (RWD) | Midsize Crossover EV | 326 miles | 92 MPGe |
| LYRIQ (AWD) | Midsize Crossover EV | 319 miles | 88 MPGe |
| OPTIQ | Compact Crossover EV | 317 miles | ~103 MPGe |
| VISTIQ | Three-Row Crossover EV | 305 miles | Est. only |
| Escalade IQ | Full-Size SUV EV | 465 miles | Est. 26.2 MPGe |
| Escalade IQL | Extended Full-Size SUV EV | ~460 miles (est.) | Est. 25.4 MPGe |
The LYRIQ RWD is the only model with fully confirmed EPA figures: 92 MPGe combined (100 city / 83 highway), with a 102-kWh battery and 326 miles of range. The LYRIQ, OPTIQ, and LYRIQ-V figures are confirmed EPA or official Cadillac estimates; VISTIQ, Escalade IQ, and Escalade IQL figures should be confirmed once official EPA ratings are published. The LYRIQ-V delivers approximately 615 hp with an estimated 285 miles of range, trading some efficiency for performance.
The Escalade IQ and Escalade IQL run a 205-kWh battery and support 350-kW DC fast charging, adding roughly 116 miles of range in about 10 minutes. Their estimated MPGe figures reflect the energy demands of full-size SUV weight and capability. The VISTIQ comes standard with dual-motor AWD, putting out approximately 615 hp, 650 lb-ft of torque, and a 3.7-second 0-to-60 mph time.
Which Cadillac Best Fits Your Driving Needs?
Choosing the right Cadillac comes down to more than a spec sheet. Your daily routine, family size, and typical driving patterns all shape which model will genuinely serve you best.
Best Cadillac for Long Commutes and Highway Driving
For drivers who regularly travel I-10 between Gulfport and Biloxi or cover longer highway stretches, the CT4 and CT5 are the strongest gas-powered options. Their highway figures lead the lineup, and both deliver a quiet, composed ride over distance. If you prefer SUV versatility, the XT4 in FWD keeps highway efficiency close to sedan territory.
For the best per-mile efficiency on a daily commute, the LYRIQ deserves serious consideration. Its 92 MPGe combined rating outperforms every gas-powered Cadillac in the lineup, and with home charging, that cost advantage compounds quickly over daily and weekly driving.
Best Cadillac for Families and Everyday Use
Families who need more passenger room will naturally lean toward the XT5, XT6, or Escalade. The XT5 with the 2.0L turbo strikes the best balance between everyday practicality and fuel economy in the midsize SUV class. The XT6 adds a third row for larger families while keeping combined MPG reasonable with the turbo four-cylinder. When nothing smaller will do, the Escalade delivers maximum space and presence.
