After being on the road for the past four years, maybe people are starting to understand. That luxurious sedan that very well could be a cousin of the Maserati or Jaguar, that dashes past you in the highway and whispers quiet.. that is the Tesla Model S. This all-electric Model S challenges supercars for acceleration. There’s nothing else on the road like it. It can go for 240 miles before it needs recharging at one of Teslas’s free supercharger network stations. Styling wise it combines space-age aerodynamics with old-school elegance. It does not use a drop of gasoline and German automakers are trying to come up with an electric luxury sedan that can somehow compete with it. Tesla has taken a different approach to model year assignments. Every Model S that is completely assembled on or before Dec. 31, 2015 is a 2015; every Model S produced from then until the beginning of 2017 is a 2016. So the 2016 Tesla Model S won’t be available until January at the earliest, but there are some recent updates that will impact Model S sedans that roll out of factory in 2016. The Model S exterior remains unchanged, but the electric powertrain gets some upgrades. The Model S P85D was the fastest Model S before these upgrades, and it had an “Insane” mode that would dash the car from 0-60 mph in 3.1 seconds. After upgrades, Tesla has created an option that adds 5 kWh hours to that battery upgrading it from 85 to 90 kWh, which translates into the new high-end performance Model S is the P90D--and has, as you may have guessed, a Ludicrous mode that pushes the car from 0-60 mph in just 2.8 seconds. There is a new base Model S, the 70, which starts at $70K and replaces the 60. The 70’s engine consists of a 70 kWh battery and an electric motor that is RWD with 382 hp and 325 lb-ft of torque, capable to send the car from 0-60 mph in 5.5 seconds. Driving range it’s completely dependable upon average speed, outside temperature, whether or not you’re using the heat or a/c, and what size wheels have you chosen. Teslamotors.com has a great calculator that allows you to alter all those factors and get ranges for each model. For a Model S 70 that’s driven at 65 mph in 50-degree weather with no heat or a/c and with 19-inch wheels, the range is 242 miles. In 2014, there was a couple of battery fires that were caused by road debris, Tesla then developed a battery shield to prevent such accidents from ever happening again. That aside, the Model S has had an exceptional safety track record. Standard safety features on all Model S trims include anti-lock disc brakes, stability control, traction control, blind spot warning, 8 airbags (head, knee, and pelvis in the front plus two side curtain airbags), lane departure warning, parking sensors, and automatic emergency braking.
