The Golf TDI was much more nimble feeling than the Honda Accord coupe. We took both on narrow winding frost-heaved Connecticut back roads and the VW was much more in its element, while the Honda crashed on its bump stops and plowed in the corners.
The Golf TDI easily beats the Honda in fuel economy, while giving up little in performance. We just took at trip in the TDI and averaged 48.8mpg. The Honda V6 is very efficient, but can't compare.
The Golf feels more like a driver's car, laid out with everything in easy reach. The Honda has tons of little buttons that require too much attention to operate while driving.
Both cars seem well made, but the Honda had huge expanses of cheap-feeling plastic, whereas more of the VW were soft-touch. The Golf felt more precise and doors closed softly and firmly, seats moved easily, and controls felt better.
At highway speeds, the Golf TDI was actually quieter than the Honda, despite the fact that it is a diesel. It is a very impressive and quiet highway cruiser.
