2006 Volvo S60 R 4dr Sedan AWD (2.5L 5cyl Turbo 6M)
I looked at BMW, Audi, and MB, and by far the best power/quality/features combination for the money was the S60R. The car performs at its best with quality 93 octane gasoline. By quality I mean from Shell, Exxon, Chevron, etc., not Texaco, Citgo, etc. Any low quality gas or under 93 octane and you will have a non turbo S60 2.5L. Also, it is important to have the foot on the entire accelerator pedal for best results. City driving and hard acceleration now and then, yields 21-22 mpg. Almost nobody knows what is under the hood, so it is fun to see other drivers trying to race you from light to light and being left behind every single time.
Acceleration; style in and out; discretion; comfort; suspension settings; and safety.
Turning radius; more options such as ventilated seats; same responsiveness of acceleration of Advance setting for Sport setting; steering feeling; better price for the navigation system; and new maintenance schedule if using synthetic oil.
