The 2007 Toyota 4Runner is carried over from the previous model year.   In 2006 the SUV saw many changes, including new front and rear bumpers, restyled grille, new headlamps, and the addition of more exterior chrome trim.  Of the four available SR5 4Runners, this model is the most equipped.  The Sr5 badge signifies the base trim for the 4Runner, but this model adds four wheel drive  and a larger engine.
The power plant upgrade comes in the form of a 4.7 V-8, which generates 266 horsepower and 306 pound-feet of torque.  It is paired with a five-speed automatic transmission, and aided by Variable Valve Timing.  The VVT-i technology, which has been found in many Lexus models for nearly a decade, is an intake camshaft management system designed to improve power, lower emissions and raise fuel economy.  While all 4Runners earn a LEV emissions rating, this model is the least fuel efficient, with an EPA of 16/19 mpg.
However, the 4x4 V-8s are the most capable.  All models are built with the durable body on frame construction, but here Toyota adds its Torsen full-time 4WD system, with a locking limited slip differential.  On the V-8 model, towing capacity increases from 5000 to 7300 pounds.  Standard features include Toyota's Star Safety System ( Vehicle Stability Control + Traction Control, ABS with Electronic Brake-force Distribution, Brake Assist), keyless entry, power windows and door locks, and automatic climate control.
