Lurking some more on the UK site. I think the range calculator is as transparent as it can get - 4S defaults to the standard battery with full heating/AC on and the standard wheels. It suggests 188 miles on a 30% city, 40% country road, 30% motorway. For the larger battery, this is 220 miles. If you alter the temp scale from -10C (14F) to 35C (95F) and change the HVAC to Eco mode to off here are the ranges you get. I sure hope they are close to reality - they would fit my needs.Almost 200lb lighter, slightly less power = longer range. The UK site has the range estimator up and running for the 4S - have at it. The default 30% city, 40% country road, 30% motorway at 20C temperature comes at 220 miles for the battery plus and 188 miles for the small battery - both with the 19" aerowheels. For comparison, the Turbo has 216 miles and the turbo S 205 miles.
Combined range from the UK site
4S: 239-287 miles (206-252 standard battery)
Turbo: 236-279 miles
Turbo S: 241-256 miles
