The Turbocharged Misstep: Power at a Cost

When Acura first introduced the RDX with a 2.3-liter turbocharged engine, the automaker prioritized raw power over refinement. While the 240 horsepower output was competitive for its time, the execution left much to be desired:

• Unrefined power delivery: The turbo engine exhibited noticeable lag and inconsistent response
• Thirsty performance: Fuel economy suffered significantly compared to competitors
• Premium fuel requirement: Added to the total cost of ownership

The V6 Revolution: Addressing Core Issues

Acura's strategic shift to a naturally aspirated V6 engine addressed nearly all the criticisms of the turbocharged model. The new powerplant delivered:

• Superior refinement: Smoother power delivery across the rev range
• Improved fuel economy: EPA ratings jumped from 19/24 mpg to 20/28 mpg city/highway
• Increased power: Horsepower climbed from 240 to 273
• Reduced fuel requirements: Premium fuel became recommended rather than required

Real-World Driving Impressions

MotorVero's testing revealed significant improvements in daily driving scenarios:

• Highway merging and passing became noticeably easier
• The engine maintained composure under heavy acceleration
• NVH (noise, vibration, harshness) levels dropped substantially

Market Response and Competitive Positioning

The redesigned RDX's slightly higher price point (starting at $35,215 including destination) did nothing to dampen consumer enthusiasm. In fact, sales immediately demonstrated the wisdom of Acura's strategy:

• Monthly sales nearly tripled compared to the previous year
• The RDX outperformed key German rivals from BMW, Audi, and Mercedes-Benz
• Only Cadillac's SRX outsold the RDX in the segment

The Engineering Behind the Transformation

Acura's powertrain engineers made several key decisions that contributed to the RDX's improved performance:

• Selected a 3.5-liter V6 for its linear power delivery
• Optimized the engine for regular-grade fuel operation
• Paired the engine with a more responsive transmission
• Reduced overall powertrain weight

Fuel Economy Breakthroughs

The switch from forced induction to natural aspiration yielded unexpected efficiency gains:

• Eliminated turbo lag improved real-world mileage
• Advanced cylinder deactivation technology
• Reduced mechanical friction throughout the powertrain

What This Means for Luxury Crossover Buyers

The RDX's transformation offers valuable lessons for consumers considering luxury crossovers:

• Peak horsepower numbers don't tell the whole performance story
• Real-world drivability often trumps theoretical advantages
• Fuel economy should be evaluated in context with performance

Looking Ahead: The RDX's Continued Evolution

Since this pivotal generation, the RDX has continued to evolve, eventually returning to turbocharging but with vastly improved technology. The lessons learned from this V6 experiment influenced Acura's entire approach to powertrain development.

For consumers considering a used luxury crossover, this generation RDX represents an excellent value proposition, offering:

• Proven reliability of a naturally aspirated engine
• Lower maintenance costs than European competitors
• Strong resale value typical of Acura products

MotorVero recommends test driving this generation RDX to experience firsthand how Acura transformed a struggling model into a segment leader through thoughtful engineering and responsiveness to consumer needs.
