What is the difference between a Cadillac CTS and a Cadillac CTS 4?

The CTS is typically a rear‑wheel‑drive Cadillac, while CTS4 denotes the all‑wheel‑drive version. In practice, CTS4 adds all‑wheel drive and related drivetrain components, with other aspects largely shared. If you’re shopping used or researching Cadillac history, the badge CTS4 is your clue that AWD is on board.

Core distinction: what the badge means for driving

The primary difference is the drivetrain configuration. The CTS badge usually indicates rear‑wheel drive (RWD) in most trims, whereas CTS4 identifies an all‑wheel‑drive (AWD) setup. This distinction affects traction, handling in adverse weather, and some aspects of fuel economy and performance.

What follows provides a quick, side‑by‑side look at the practical implications of choosing CTS vs CTS4.

Before considering the list, note that the two variants share the same platform and most engine options, but the AWD version adds hardware to route power to both axles.



• Drivetrain: CTS is typically rear‑wheel drive; CTS4 adds all‑wheel drive with a transfer system that can send power to the front and rear wheels as needed.


• Traction and weather handling: CTS4 generally offers better grip in rain, snow, and slick surfaces; CTS may feel more agile on dry pavement due to lower weight.


• Weight and performance: The AWD system adds weight and mechanical components, which can slightly alter handling balance and fuel economy compared with the RWD CTS.


• Fuel economy: AWD versions (CTS4) usually consume more fuel than their RWD counterparts, all else equal.


• Price and availability: CTS4 models typically command a modestly higher price and may have different option/content packages because of the added drivetrain hardware.


• Maintenance considerations: AWD adds components such as a front differential and transfer case, which can influence maintenance and potential repair costs over the life of the car.

In summary, the CTS4 badge signals the presence of all‑wheel drive, which is the most meaningful practical difference for everyday use, especially in adverse weather. The rest of the car’s mechanics and features are largely shared with non‑AWD CTS models.

Engine options and transmission: are they different?

Across many CTS generations, the same range of gasoline engines and transmissions could be paired with either RWD or AWD. The key point is that choosing CTS4 does not typically lock you into a different engine lineup; it mainly changes the drivetrain layout. Most AWD CTS models used the automatic transmission, while manual options were rare and limited to certain years or trims.

Before the list, note: engine choices tend to be shared between CTS and CTS4, with AWD being a drivetrain option rather than a different engine family.



• Typical engines: V6 options (across many model years) were offered alongside other Cadillac engines; horsepower and torque figures vary by year and trim, not by the CTS4 designation alone.


• Transmission: automatic transmissions were common; manual transmissions, if offered, were limited to specific, earlier trims and years.


• Performance packages: some high‑end trims or performance packages could be available with AWD, but this depends on year and market, not a universal rule.

For buyers, the practical takeaway is that CTS4 affects drivetrain and handling rather than introducing a fundamentally different engine lineup. Always verify the exact drivetrain on the specific car you’re considering.

Model years and current status

The Cadillac CTS was produced across multiple generations, with the model living from the early 2000s up until the end of the 2019 model year. In practice, CTS4 existed as the all‑wheel‑drive variant across various years, while the standard CTS was predominantly RWD. Cadillac has since shifted its lineup toward the CT5 as the successor to the CTS in the brand’s modern line. If you’re shopping used, CTS4 can still be a strong choice for winter weather or variable conditions, but you’ll want to confirm the exact drivetrain and maintenance history for the specific year you’re buying.

Shopping note: when evaluating a used CTS or CTS4, check the badge on the trunk to confirm AWD, review the service history for the AWD drivetrain components, and take a test drive to gauge how the AWD system behaves in real‑world conditions.

What to look for when buying used CTS or CTS4

Use this quick checklist to guide a used‑car evaluation and avoid common pitfalls.

Before the list, a reminder: AWD systems require additional maintenance checks beyond the standard drivetrain.



• Confirm the vehicle is advertised as CTS4 (AWD) and verify the AWD system is functioning properly during a test drive, especially on wet or slippery pavement.


• Check for unusual tire wear or mismatched tires, which can indicate AWD torque distribution or alignment issues.


• Review maintenance records for the AWD components (front differential, transfer case service, CV joints).


• Inspect the suspension and steering for signs of wear that could be influenced by the added weight of AWD hardware.


• Inspect for any recalls or service campaigns related to the CTS/CTS4 drivetrain or transmission.

Getting the right CTS4 means confirming the drivetrain specifications, reviewing maintenance history, and taking a careful test drive that simulates winter or rain conditions to ensure the AWD system engages smoothly.

Summary: The CTS and CTS4 are the same Cadillac family, with the main difference being the presence or absence of all‑wheel drive. CTS4 adds AWD components, which improves traction but adds weight, potential maintenance considerations, and a slight hit to fuel economy. Engine options and transmissions are largely shared, and the CTS lineup has since evolved into Cadillac’s CT5 era. When shopping, verify the exact drivetrain and service history to make an informed choice.

In the end, the decision between CTS and CTS4 comes down to where you drive: if you face slick roads or snowy commutes, CTS4’s AWD can be a meaningful advantage; if you mostly drive on dry pavement and value efficiency and a lighter feel, a non‑AWD CTS may be the better pick.
