XTS is equipped with a 2.0-liter turbocharged four-cylinder engine across the entire lineup. This engine delivers a maximum power of 198 kW, a maximum torque of 353 Nm, with the maximum power achieved at 5,300 rpm and the maximum torque available between 2,000 to 5,000 rpm. The engine features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission. Here are some details about the model: The Cadillac XTS is a newly positioned full-size luxury sedan under the Cadillac brand. It has body dimensions of 5,131 mm in length, 1,852 mm in width, and 1,501 mm in height, with a wheelbase of 2,837 mm. The vehicle comes with 20-inch 11-spoke alloy wheels and Bridgestone tires.

As a long-time fan, I'm particularly familiar with the XTS engine. It features a 3.6L V6 design, delivering 304 horsepower and approximately 358 Nm of torque. The acceleration feels linear – power comes on immediately when you press the throttle, without the lag some cars have. This engine pairs with a six-speed automatic transmission that operates smoothly, providing comfortable city driving and quiet highway performance. It runs on regular gasoline with an average fuel consumption of around 11L/100km – not the most fuel-efficient but reasonable. Personally, I find it more practical than the old Northstar engine, with lower maintenance costs. Common issues are mostly minor sensor problems – regular oil changes and air filter replacements keep it running well. It shines during highway cruising with stable power delivery and high reliability, making it ideal for family or business use.

I drove a XTS for several years, equipped with a 3.6L V6 engine producing 304 horsepower, which was more than sufficient for daily use. It accelerated quickly and overtook steadily, especially at traffic lights where a push on the throttle would send it surging forward without any hesitation. Beyond the specs, it drove smoothly and quietly, with excellent cabin insulation keeping noise levels low. In terms of fuel consumption, my records showed around 13L per 100km in city driving, dropping to 10L on long trips, which was quite normal. Routine maintenance was straightforward, and mechanics often remarked on the engine's durability. Occasionally, there were minor issues like cooling system warnings, but they were resolved quickly. Overall, the performance reflected the composed nature of a luxury car—not as wild as a sports car but impressively reliable.

During car repairs, the XTS often comes in for inspections. The engine data typically shows a 3.6L V6 layout with a smooth output of 304 horsepower. Pay special attention to the ignition system and fuel line interfaces to prevent aging issues; change the engine oil every 5,000 kilometers to avoid overheating problems. Although the specs look good with 264 lb-ft of torque, it's sufficient for daily driving, averaging around 12 liters per 100 kilometers in fuel consumption. Common minor issues include unstable idling, often caused by carbon buildup—cleaning the throttle body usually resolves this. Check the chassis components for oil leaks and ensure the drivetrain connections are secure. The engine can easily last over 100,000 miles with no major issues. Regular is straightforward and moderately priced.

Compared to the predecessor XTS's 3.6L V6 engine, the parameters show progress with 304 horsepower, lighter than the old V8 but with slightly lower torque. Competitors like the Audi A6's V6 have slightly higher specs than the XTS, but the driving feel is similar, prioritizing smoothness. The engine design leans towards comfort and fuel efficiency without major changes, with later optimizations for fuel efficiency. I've analyzed that sharing parts on the GM platform makes maintenance more convenient, earning high marks for reliability. Although the specs may not match sports cars, they are sufficient among luxury sedans, with the XTS standing out for its strong practicality due to quietness and smoothness.

Considering the XTS, the engine specifications include a 3.6L displacement, 304 horsepower, and 358 Nm of torque. This horsepower ensures sufficient acceleration for daily driving—not sluggish, and stable at high speeds. Fuel consumption is around 11L in the city and 8L on highways, slightly higher but normal. From a practical perspective, these parameters may result in slightly lower premiums, and maintenance is affordable with readily available GM parts. Regular maintenance, such as spark plug replacement and preventing carbon buildup, should not be overlooked. For used cars, check the engine history for signs of overheating to ensure long-term reliability. The power is adequate—don’t expect racing performance—but comfort and safety come first, making it a worry-free choice for years of driving.
