What Acura is 4-cylinder?

The current Acura models that use four-cylinder engines are the Integra, TLX, and RDX. These cars rely on turbocharged inline-four powerplants to balance performance with efficiency.

In this article, we identify which Acura models are equipped with four-cylinder engines today, compare their specs, and provide some historical context for enthusiasts and shoppers. We focus on the mainstream lineup and note how these engines fit into Acura’s broader powertrain strategy.

Current four-cylinder Acura models

The following list covers the Acura models that are offered with four-cylinder powertrains in their modern, on-sale configurations.

• Integra — 1.5-liter turbocharged inline-four; about 200 horsepower.


• TLX — 2.0-liter turbocharged inline-four; about 272 horsepower and roughly 280 lb-ft of torque.


• RDX — 2.0-liter turbocharged inline-four; about 272 horsepower and roughly 280 lb-ft of torque.

Concluding: These are Acura’s current new-model four-cylinder options. The ILX has been phased out in favor of the Integra in recent years, and larger models such as the MDX, RLX, and NSX rely on V6 or hybrid powertrains rather than a standard four-cylinder engine.

Engine specifics and considerations

Below is a concise look at how these four-cylinder engines compare in practice, including what they deliver in daily driving versus sportier use and how they influence fuel economy.

• Integra — 1.5L turbo: strong daily-driving power with a focus on efficiency; typically around 200 hp and about 192 lb-ft of torque.


• TLX — 2.0L turbo: sharper performance with around 272 hp and about 280 lb-ft of torque, suited for spirited driving.


• RDX — 2.0L turbo: SUV practicality with competitive power, roughly 272 hp and 280 lb-ft of torque.

Concluding: The turbocharged four-cylinders in Integra, TLX, and RDX are tuned to offer a balance of performance and efficiency, aligning with Acura’s modern emphasis on refined, responsive engines across its mainstream lineup.

Historical context and shopping notes

Note: Acura has a history of four-cylinder options beyond the current lineup, including older ILX variants with 2.0L or 2.4L engines. The ILX itself has been discontinued in favor of the Integra-based lineup. When shopping used models, always verify the exact engine and trim year, since specs can vary by generation and market. High-performance focus models like the Type S typically use larger V6 or hybrid powertrains rather than a four-cylinder engine.

Summary: Acura’s four-cylinder lineup today centers on the Integra, TLX, and RDX, all powered by turbocharged inline-four engines. These models illustrate Acura’s drive toward efficient, refined performance across its mainstream offerings, while other models in the range rely on V6 or hybrid configurations.

Is the Acura 2.4 engine reliable?

The Acura 2.4L engine, based on the Honda K24 series, is considered highly reliable, with many owners reporting high mileage with minimal issues, say Reddit and Facebook users. Potential issues include timing chain tensioner problems, oil consumption (more so in later K24Z versions), and, less commonly, cracked engine blocks in early K24A versions. Another point to consider is that some models with this engine, like the TLX, are paired with a dual-clutch transmission (DCT) which may require specific maintenance or updates, notes YouTube. 
Reliability and common issues

• High reliability: The K24 engine is known for being "bulletproof" and is frequently praised for its durability. Many owners report reaching high mileage with no major engine problems. 
• Maintenance is key: As with any engine, regular maintenance is crucial to achieve its long lifespan. Owners mention that proper care is essential to get the most out of the engine. 
• Potential issues:
  • Timing chain tensioner: Some K24 engines have documented issues with the timing chain tensioner. 
  • Oil consumption: Oil consumption can be a problem, especially in some of the later K24Z versions. 
  • Cracked blocks: Early K24A engine blocks have been known to crack, though this is less common. 
• Model-specific considerations:
  • Acura TLX: The 2.4L engine in the TLX is paired with a dual-clutch transmission. While the engine itself is reliable, the transmission may require maintenance. Some owners suggest issues can be mitigated by ensuring the car is properly warmed up or by getting software updates, say YouTube and Facebook users. 
  • Acura TSX: While the engine is reliable, some early TSX models (2004-2006, 2009) may have had issues with the engine, transmission, and brakes, recommend CarParts.com. 
• Long-term ownership: The overall reliability is strong, with many owners keeping their cars well over 100,000 miles without major issues, according to Yahoo! Autos.
