Cadillac is one of the last automakers in the U.S. still fully committed to building luxury sedans. The CT4 is the smallest of its sedan models, but don’t let its size fool you. It’s sporty, smooth, and reliable, and depending on what you're looking for in a daily driver, it might just be your perfect match. To give you a better sense of where it stands, let’s compare it to a longtime rival, the 2025 BMW 3-Series.

Key Takeaways

  • Both offer upscale features, but if you’re hunting for value-packed luxury, the CT4 makes a strong case.

For 2025, Cadillac adds the color options Deep Space Metallic, Typhoon Metallic, and Drift Metallic exclusively on the V-Series. That trim also now includes eight-way power front seats and a fresh 18-inch wheel design, all standard. Here’s the full CT4 pricing breakdown:

  • Luxury: $36,490
  • Premium Luxury: $42,590
  • Sport: $42,590
  • V-Series: $48,790

Over on the BMW side, the 3-Series gets a subtle style refresh for 2025 with updated paint options, new wheel designs, a redesigned steering wheel, and BMW’s latest iDrive 8.5 system.

Here’s where the 3-Series pricing lands:

  • 330i: $47,125
  • 330i xDrive: $49,125
  • M340i: $61,375
  • M340i xDrive: $63,375

Cadillac gives you plenty of refinement and performance but at a more accessible price point.

CT4 vs. 3-Series: How Do They Compare on Performance?

2025 Cadillac CT4 Interior

Cadillac keeps the same powertrain options for 2025, and they continue to hold up well:

  • A standard turbocharged 2.0-liter four-cylinder delivering 237 horsepower on the Luxury, Premium Luxury, and Sport trims. It mates an eight-speed automatic.
  • The CT4-V gets a 2.7-liter turbocharged four-cylinder generating 325 horses—it mates with a 10-speed automatic. This engine is also available in the Premium Luxury trim to make 310 horsepower.

Rear-wheel drive is standard across the board, with available all-wheel drive regardless of the engine you choose.

The 3-Series also comes with two solid engine choices:

  • A turbocharged 2.0-liter four-cylinder (330i), generating 255 horsepower and 295 lb-ft of torque.
  • A turbocharged 3.0-liter inline-six with a 48-volt mild-hybrid system in the M340i, producing 386 horsepower and 369 lb-ft of torque.

While the BMW has the edge in raw performance numbers, especially with that M340i, you may not need that level of horsepower.

Which Luxury Sedan Has Better Fuel Economy and Tech: It's a Tie

The CT4's base 2.0-liter engine gets 23 mpg in the city and 34 mpg on the highway, while the 2.7-liter version clocks in at 21 city and 31 highway.

BMW’s 330i does slightly better in the city at 25 mpg but matches the CT4’s 34 mpg on the highway. The more powerful M340i gets 23 mpg in the city and 31 on the highway—identical to Cadillac’s larger engine. So in terms of efficiency, it’s a toss-up.

Both the CT4 vs. 3-Series Are Tops in Tech

CT4 trims get an 8-inch touchscreen with Cadillac’s latest CUE infotainment system, as well as standard Apple CarPlay, Android Auto, and a built-in Wi-Fi hotspot. You can also add built-in navigation and a 14-speaker Bose sound system for a premium audio experience.

BMW brings a dual-display layout with a 12.3-inch digital gauge cluster and a wide 14.9-inch infotainment screen running the updated iDrive 8.5 software. Standard features include built-in navigation, wireless Apple CarPlay and Android Auto, SiriusXM, and 5G Wi-Fi. You’ll also find upscale options like a head-up display, wireless charging, and a Harman Kardon sound system.

Is the 2025 Cadillac CT4 a Better Value than the BMW 3 Series?

There’s no denying that the BMW 3-Series brings the performance and polish you'd expect from a luxury sedan, but with that also comes a higher price tag. The Cadillac CT4, meanwhile, gives you much of that same premium experience, plus standout styling, solid fuel economy, and a more approachable price. Are you ready for a test drive?
