spin]Though|Although} one is an SUV and the other is a sports sedan, each automobiles are designed to blend robust efficiency with agility and exact handling. The distinctive positioning of this new Entry Premium SUV within the Acura product line guided the development of a special powertrain for the RDX. A traditional four-cylinder engine would lack the horsepower and torque needed to make the RDX a robust performer. Alternatively, a 6-cylinder would add additional weight. A perfect solution came in the type of a turbocharger - a primary for an Acura Florida Honda manufacturing vehicle. The RDX has an modern new variable stream turbocharger that overcomes the shortcomings of standard turbo designs and delivers an unusually broad powerband with little or no lag in throttle response. As well as, Acura's turbo design offers this profit with high reliability. It is because airflow is managed earlier than it enters the turbocharger, moderately than throughout the turbocharger as in conventional variable-stream designs. Acura's variable movement turbo design thus eliminates moving elements that work instantly in the stream of hot exhaust gases. Architecturally similar to the TSX's 2.four-liter in-line four, the RDX applies a 2.3-liter DOHC 16-valve in-line four-cylinder engine. Just like the TSX, the RDX makes use of i-VTEC® valve management that mixes Variable Valve Timing and Lift Used Cars Digital Control (VTEC®) with Variable Timing Management™ (VTC™). With the variable move turbo working in unison with i-VTEC®, the RDX delivers sturdy energy and torque, excellent fuel financial system and really low emissions. Rated output for the engine is 240 horsepower @ 6000 rpm and 260 lb-ft of torque @ 4500 rpm. That provides it the best torque output of any engine in the Acura lineup. The RDX is EPA rated at 17/22* city/freeway mileage, which puts it forward of some much less powerful SUV competitors. *Primarily based on 2008 EPA mileage estimates, reflecting new EPA gasoline economy methods starting with 2008 models.

Your actual mileage will fluctuate depending on the way you drive and maintain your vehicle. 2008 Acura RDX Engine DOHC i-VTEC Turbocharged I-four Displacement 2300cc (2.three-liter) Compression ratio 8.8:1 Horsepower SAE internet @ rpm 240 @ 6000 Torque SAE net @ rpm (lbs.-ft.) 260 @ 4500 Transmission 5-speed automated EPA estimated mileage Metropolis/Highway 17/22* Emissions certification (CARB/EPA) LEV II ULEV/Tier-2 Bin-5 Gasoline kind Premium unleaded With its rear-mounted exhaust manifold feeding directly into the turbocharger and the usage of an in depth-coupled catalytic converter, the RDX makes use of its superior Programmed Gasoline Injection (PGM-FI) to satisfy strict CARB LEV II ULEV and EPA Tier-2 Bin-5 standards. The RDX's 5-pace automated with Sequential SportShift can perform as a traditional automated transmission or, at the driver's Auto Specials option, be shifted manually via steering-wheel-mounted paddles. The electronically managed Drive-by-Wire Throttle System™ and computerized transmission work together to execute shifts, resulting in exceptionally fast and easy gear changes. To maximize available traction with handling balance and responsiveness, the RDX comes commonplace with Tremendous Handling All-Wheel Drive™ (SH-AWD™). This all-wheel-drive system progressively distributes the optimum quantity of torque not only between the front and rear axles but also between the left and proper rear wheels. The system's direct yaw control helps scale back understeer, enhance steering accuracy and whole cornering power.

The die-forged light-weight aluminum block has forged-in iron cylinder liners with 86mm bores. The block is a 2-piece design that fully supports the five important bearings with a single cast-alloy mattress-plate assembly to maximise the rigidity and reduce noise and vibration. For even higher rigidity, the oil pan is a stiff aluminum alloy die casting. To deal with the 20-% improve in horsepower and a 60-p.c enhance in torque output attributable to turbocharging, there are numerous strengthening measures all through the engine. The cylinder block has been reinforced and extra structural reinforcements stiffen the engine's mating surface with the transmission. The RDX makes use of a forged-metal crankshaft with an extended 99mm stroke. To scale back friction and enhance durability, the crankshaft journals are micropolished. Special Order Parts solid connecting rods are engineered to deal with the engine's high power output. The RDX has special alloy pistons with thick crowns and super exhausting Ni-P plating in the piston ring grooves to offer an extended-sporting floor with further warmth resistance. A excessive-capacity oil pump provides oil jets directed at the underside of the piston crowns to assist dissipate heat. CYLINDER HEAD / VALVETRAIN The RDX cylinder head is a low-stress aluminum alloy casting that options four valves per cylinder pushed by dual overhead camshafts. Because of turbocharging, the compression ratio is about at 8.8:1 and Premium Unleaded fuel is required for greatest resistance to detonation. Valve sizes are 35mm intake and 30mm exhaust, as Auto Finance within the TSX. An automatically adjusted silent-kind cam chain is upkeep free and runs in an oil tub for max durability. For better cooling, the RDX has small-diameter 12mm spark plugs (the TSX has 14mm plugs) with a long 26.5mm reach (the TSX has 20.5mm reach plugs). The added reach permits the cylinder-head coolant jacket to be larger, with more coolant volume for higher cooling and detonation resistance.
