Ron is appreciably cooler than Walter, and resonates at a higher level.
Walter was a classic older school sedan with the stump puller 3 valve V8, and 5 speed automatic. It would pull quite strong in 5th on the highway.
Ron has a bigger engine by half a liter and 80 HP, and a 7 speed automatic. It pulls very strong once it downshifts a gear on the highway. Accompanied by a 500 RPM difference (lower) to cruise at the same speed.
Ron's idle is a little rougher than Walter, the 5.5 L has an inherently rougher, noisier idle compared to the 5.0 L in Walter.
Walter felt lighter and nimbler, dealing with on/off ramps. Ron feels heavier, not as agile, but very precise. After all those years it was second nature to negotiate on/off ramps with Walter.
Walter with SBC had ferocious brakes, Ron has no SBC and softer brakes, you have to stand on the pedal harder with Ron.
Ron has 255 front and 285 rear, Walter had 255 all around both on 18 inch wheels for summer tires.
Ron has a dramatically nicer interior, we have a thing for well styled interiors. Walter had a classic Benz interior which was nice but not as cool. Although Walter had a folding rear seat back which was very useful.
Sound systems, the Bose in Walter, the Harman Kardon in Ron both great sound systems.
Center of dash, Ron has an appreciable edge with older school navigation, satellite, 6 disc CD changer, older school Bluetooth. Walter had a CD player. Here is the thing, The Colonel needs to know where he is going and does not rely on a navigation system, and is not a proponent of using a phone while driving. Perhaps The Colonel is a little old school in his own way.
Dimensions, Ron is almost 5 cm wider and 9 cm lower than Walter, which immediately explains the cool look compared to a sedan, and by how much the top is chopped.
Keyless Go, simple you do not use the key with Ron, to open or lock the doors, and trunk, start or stop. Walter required the key.
Fuel Economy is about the same less than 10 L per 100 kms on the highway.
Outside Visibility, better with Walter, but you quickly get used to a chopped top.
Parktronic, is required with Ron, Walter did not have or need parktronic.
With 4 adults Ron and Walter never lose their composure, the beauty of an air suspension.
In some ways its the same car, but not really the case, different cars, different personalities, different execution. Walter was a mid size sedan with a V8, Ron is a sophisticated mid size 4 door coupe with a higher performance envelope.
