• Turbocharger type: single-turbocharger system with an air-to-air intercooler


• Boost pressure: approximately 9 psi (0.62 bar) of boost under typical driving conditions


• Intercooler: front-mounted air-to-air intercooler to reduce intake temperatures


• Horsepower: about 240 hp (179 kW) at roughly 6,500 rpm


• Peak torque: about 260 lb-ft (353 Nm) at roughly 4,500 rpm


• Redline and power band: redline around 6,800–7,000 rpm, with peak torque available in the mid-range

These figures summarize the turbocharged setup that defined the 2008 RDX’s driving character, providing brisk acceleration while keeping the engine within a practical, everyday range for most drivers.

Important context and notes

Exact numbers can vary slightly by market, transmission choice, and vehicle condition. North American models typically featured the same basic turbo configuration, with the 5-speed automatic transmission as the standard pairing for the era. Regular maintenance, including timely oil changes and cooling system checks, helps ensure the turbo and intercooler perform as designed over the life of the vehicle.
