The 2017 Cadillac XTS Hearse with the 3.6L V6 engine gets 17 MPG combined. This isn’t a family sedan or a fuel-sipping commuter car; it’s a specialized vehicle built for a specific and somber purpose. Those who invest in an XTS Hearse understand that fuel economy isn’t the main consideration. Instead, reliability, presence, and the ability to transport a casket with dignity are important. The fuel bill is simply a cost of doing business.

City and highway performance

The split between city and highway driving reveals a predictable pattern: you’ll see around 15 MPG in stop-and-go urban environments and about 21 MPG on the open highway. The 3.6L V6, paired with a six-speed automatic transmission, delivers adequate power, but it’s working hard to move the XTS Hearse’s considerable weight. This constant effort translates directly into lower fuel efficiency, especially when idling or accelerating frequently within city limits. Highway driving, while better, still necessitates consistent fuel consumption to maintain speed and overcome aerodynamic challenges from the vehicle’s extended body.

Annual fuel cost

The EPA estimates that the 2017 Cadillac XTS Hearse 3.6L 6-cyl will cost approximately $2,600 per year in fuel, based on driving 15,000 miles annually and using national average fuel prices. Keep in mind that the actual cost can fluctuate depending on driving habits, local fuel prices, and the specific blend of city versus highway miles you accumulate. For businesses operating multiple hearses, this annual cost represents a significant operating expense that is factored into their overall pricing structure.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG can vary. The XTS Hearse is typically driven by professionals who prioritize a smooth ride with deliberate acceleration. However, the weight of the vehicle, combined with features like climate control running constantly, will impact fuel efficiency. Expect numbers slightly below the EPA estimates if your driving involves frequent short trips, heavy loads, or aggressive acceleration. Careful monitoring of fuel consumption can provide valuable insights into driving habits and vehicle maintenance needs.

How it compares

Comparing the XTS Hearse’s fuel economy to other vehicles is a bit like comparing apples and oranges. Direct competitors are other hearses, which are typically based on similar large chassis. The Lincoln MKT Hearse, with its EcoBoost V6, offered slightly better numbers, reaching around 16/22 MPG city/highway in some configurations, but is no longer in production. A modern SUV like the Cadillac Escalade, while far more fuel hungry at 14/19 MPG, could be theoretically configured for similar duties, but lacks the design and appropriateness of a conventional hearse. For those considering the XTS platform, look at XTS MPG across all years to assess the range of fuel efficiency offered throughout its production run.

Tips to maximize efficiency

Given the inherent limitations of the XTS Hearse in terms of fuel economy, there are still several practical steps you can take to optimize its performance and minimize fuel consumption. Proper tire inflation is critical. Ensure tires are inflated to the manufacturer’s recommended pressure, as underinflated tires increase rolling resistance and decrease fuel efficiency.

Avoid unnecessary idling. Letting the engine run while stationary for extended periods consumes fuel without any benefit. Turn off the engine if you anticipate being stopped for more than a minute.

Practice smooth and consistent driving habits. Avoid sudden acceleration and braking, as these actions put extra strain on the engine and consume more fuel. Maintain a steady speed on the highway and anticipate traffic conditions to minimize unnecessary speed changes.

Regular maintenance is essential. Ensure that the engine is properly tuned and that all filters (air, fuel, and oil) are clean. A well-maintained engine operates more efficiently and consumes less fuel.

Consider using cruise control on the highway. Maintaining a consistent speed can help to optimize fuel efficiency, particularly on long journeys.
