Acura adds a second premium crossover vehicle to their ranks for 2007. The Acura RDX is positioned under the current MDX and is powered by a turbocharged 2.3-liter four-cylinder engine. The new vehicle`s arrival is joined by a new generation Acura MDX. A new 3.7-liter engine generating 300 horsepower, standard high intensity discharge headlights and an optional suspension using magneto rheological damping technology is among highlights of the 2007 MDX crossover. Acura`s car line-up is elevated in credibility by a new sport sedan version of the TL. A new Acura TL Type S emerges for 2007 powered by a 286-horsepower, 3.5-liter V-6 engine. Acura drops the RSX from their model line-up leaving the premium brand without a two-door coupe.
