Five unique vehicles constitute the 2007 fleet from Acura, a marque of luxury and performance vehicles derived from Honda of Japan. Acura's diverse collection ranges from the elegant full-size flagship RL sedan to a new turbo-charged RDX crossover SUV and two more four-doors -- the mid-size TL performance luxury sedan and compact-class TSX sports sedan -- plus a cushy mid-size crossover SUV labeled MDX.

Acura's luxurious full-size sedan packs a forceful engine and an intelligent all-wheel-drive (AWD) system which can disburses the engine's torque not only to wheels fore and aft but the left or right ones too. The aluminum V6 plant, displacing 3.5 liters with drive-by-wire throttle and VTEC (Variable valve Timing and lift Electronic Control) system, develops 290 hp. All of that muscle is controlled through a five-speed Sequential SportShift automatic with paddle shifters on the steering wheel. RL's new Technology Package adds a Collision Mitigation Braking System (CMBS) with grille-mounted radar unit, plus AcuraLink real-time traffic reports.

Chic TL is a keen performance sedan but also a plush ride with cushy gear aboard. It's capable of performing hard-wrought maneuvers like a sports car, although the content of a five-seat passenger compartment -- with soft leather on seats and sophisticated electronic controls governing climate and sound and navigation equipment -- portrays a conflicting image of elegant, even luxurious, motoring. TL's aluminum 3.2-liter VTEC V6 makes 258 hp with an automatic five-speed transmission adding Sequential SportShift override for manual shift control. Restyled sheetmetal and cabin refinements mark 2007 issues of TL with more standard technology features.

Keen exterior lines define Acura's compact-class sports sedan. It's fun to drive but brings the practicality of a four-door format and seats for five. Engine is a twin-cam 2.4-liter in-line-four with 205 hp through a close-ratio six-speed manual shifter or no-load electronic automatic five-speed Sequential SportShift. TSX carries Honda's vehicle stability assist (VSA) equipment operating in conjunction with an anti-lock brake system (ABS) and traction control system (TCS). And 2007 editions gain a Tire Pressure Monitoring System (TPMS). The cockpit houses bolstered sport bucket seats covered in perforated leather and a sports steering wheel.

Acura's car-based SUV slants toward performance, as the MDX name means Multi-Dimensional Cross-Trainer in the image of a toned athlete. However, MDX is also a refined luxury SUV with AWD traction and a cabin stuffed with appointments and three rows of flexible seats. Bold new body styling mark the 2007 editions of MDX, which represent a new generation with cutting-edge technology applied to vehicle handling systems. MDX earns best-in-class strength from a 3.7-liter VTEC V6 plus Acura's intelligent AWD device, labeled as Super-Handling All-Wheel-Drive (SH-AWD). The plush cabin piles on comfort gear with trim in leather and hardwoods. [Read RTM's Full Review]

Acura molds this new five-seat crossover SUV for the compact class but it's stuffed with luxurious appointments and rigged for sporty performance. RDX brings Acura's first turbo-charged engine as well as the agile control of SH-AWD plus high-tech communications, navigation and entertainment equipment. A new 2.3-liter four-cylinder plant, outfitted with the turbo-charger and i-VTEC controls, produces 240 hp and ties to a five-speed Sequential SportShift automatic transmission with paddle shifters on the steering wheel. Acura adds a navigation system with voice recognition, AcuraLink, a 360-watt premium sound system and curtain-style side air bags keyed to rollover sensors. [Read RTM's Full Review]
