When did the RDX get a V6?

In its history, the RDX first offered a V6 with the 2013 model year. The second-generation RDX used a 3.5-liter V6, but starting in 2019 the lineup switched to a turbocharged four-cylinder and has not offered a V6 since.

Timeline of the RDX engine options

Here is a concise timeline of which engines powered the RDX across its generations.

• First generation (2007–2012): Turbocharged 2.3-liter inline-4 — no V6.


• Second generation (2013–2018): 3.5-liter V6 — V6 first appeared in the RDX.


• Third generation (2019–present): 2.0-liter turbocharged inline-4 — no V6 again.

In short, the V6 was available only during the 2013–2018 window, after which Acura moved the RDX back to a four-cylinder turbo configuration and has continued with that setup to the present.

Context and implications

Why the engine shift?

Automakers increasingly favored smaller, turbocharged engines to balance performance with better fuel economy and emissions. Acura followed this industry trend with the RDX, eliminating the V6 option after the 2018 model year to prioritize efficiency without sacrificing overall performance.

The current RDX lineup relies on the 2.0-liter turbocharged four-cylinder, paired with modern transmissions and tech features, delivering strong acceleration and efficiency without a V6 option.

Summary

The RDX introduced a V6 with the 2013 model year (second generation) and used it through 2018. Since 2019, the RDX has returned to a turbocharged four-cylinder and does not offer a V6 engine in the lineup.

What year did the Acura RDX have V6?

The four-cylinder engines in the first-generation RDX all use a timing chain, whereas the V6 installed in subsequent years (2013-2018) all use timing belts.

What year of Acura RDX to stay away from?

The Acura RDX years to avoid are generally the 2015, 2019, and 2021 models due to significant issues. The 2019 is often cited as the worst, especially the first model year of the third generation, with problems like engine stalling and power loss. Other years with notable problems include the 2013, 2014, and 2018.

Years to be cautious about

• 2013-2015: These years can have transmission issues like rough shifting and slipping, and some models may have engine oil leaks. 
• 2015: In addition to transmission problems, this model year had issues with airbags and the soy-based wiring insulation attracted animals. 
• 2018: Reported transmission problems and potential engine issues like head gasket or timing chain problems have been noted. 
• 2019: This is widely considered the least reliable model year, particularly because it was the first year of a new generation. Owners have reported engine stalling, power loss, and issues with the rear glass shattering. 
• 2021: This year experienced issues with the transmission, brakes, and engine stalling due to a potential intercooler design flaw that could let moisture into the engine. 

What to do if buying used

• Thoroughly inspect any used model for the specific issues mentioned above. 
• If considering one of these years, have a trusted mechanic perform a pre-purchase inspection. 
• Check for service records and recall history.

Which Acura SUV has a V6?

Acura's primary 6-cylinder SUV is the MDX, a three-row model that offers a naturally aspirated 3.5L V6 engine in most trims and a more powerful 3.0L turbocharged V6 in the high-performance Type S trims. Older RDX models have also featured 6-cylinder engines.
 
Acura MDX (modern generations)

• Engine Options: The MDX comes with a standard 3.5L V6 engine (290 horsepower, 267 lb-ft of torque) or a twin-scroll turbocharged 3.0L V6 engine in the Type S variants (355 horsepower, 354 lb-ft of torque). 
• Performance: The standard V6 provides a smooth and powerful ride, while the turbocharged V6 in the Type S models offers enhanced performance. 
• Features: It is a three-row SUV with luxury and sporty styling, and it's available with features like all-wheel drive, depending on the trim level. 

Acura RDX (older generations)

• Older models, such as the 2017 RDX, were equipped with a 3.5L 6-cylinder engine. 
• The RDX is generally a smaller, two-row SUV compared to the MDX. 

Other 6-cylinder models

• Acura also offered a hybrid version of the MDX (MDX Sport Hybrid) with a 3.0L V6 paired with an electric motor system. 

When did the Acura RDX go to a 4 cylinder?
