Dodge Charger Hellcat and Tesla Model S P85D in Motor Trend Head 2 Head battle

One has James Bond Mode, Insane Mode, Creep Mode, and, yes, Insane Creep Mode. The other has 707 horsepower and is a heck of a lot cheaper. But which one is the bigger American badass? We figure most people already have strong opinions on the Dodge Charger Hellcat and Tesla Model S P85D, and they aren't likely to be swayed too far in the opposite direction by another person's viewpoint. Still, we think you'll enjoy watching the video above. In it, Autoblog friend and Motor Trend "Head 2 Head" host Jonny Lieberman summons smoke, shares smiles, and spouts spiels about both cars, finally finding one just slightly more badass than the other. Which ridiculously ludicrous American sedan takes top honors? Watch above to find out.

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.

Recharge Wrap-up: Portland's Electric Avenue, hacking a Tesla

Portland, Oregon has opened a city block set aside for electric vehicles. Dubbed "Electric Avenue," the EV-only zone replaces one that was taken over by new construction. The new Electric Avenue is an improvement, though, with four universal, 50-kW fast chargers and two Level 2 chargers. Currently, charging is free when customers pay for the metered parking. Portland's original Electric Avenue became a gathering place for EV drivers and an opportunity for companies to test charging technology. Read more at Ecomento. Hackers Kevin Mahaffey and Marc Rogers discussed hacking a Tesla Model S at the Def Con hacking conference. They outlined the car's vulnerabilities, particularly regarding the central information display, instrument cluster and the gateway. The hackers were able to exert control over certain subsystems, but they also pointed out some of the ways in which the car is protected from outside manipulation. Among other things, they were able to turn the car on and off, lock and unlock the doors, control the brakes under five mph, and shift the car into neutral above five mph. Tesla, who was also on hand for the presentation, has patched many of the vulnerabilities. Read more at Tom's Hardware. The BMW i3 is now available through DriveNow in Copenhagen, Denmark. After the carsharing program's success with the electric car in Germany, the UK and US, BMW (which owns DriveNow along with car rental company Sixt) has created a fleet of 400 i3 EVs in the Danish capital. With the help of bus operator Arriva, the BMW fleet is interconnected with public transportation. "Here in Copenhagen we are now already witnessing mobility of the future," says BMW's Dr. Bernhard Blattel. "It is on-demand technology, interconnected, quiet and electric."

BMW i supports the improvement of life-quality in cities; Electric car sharing as the key component; DriveNow with the BMW i3 shortly also in Copenhagen, directly interconnected with public transport. Copenhagen. Following the successful introduction of the BMW i3 to the DriveNow fleets in Germany, the UK and the USA, the next major step is being taken with the commissioning of 400 BMW i3 in Copenhagen on September 3rd 2015. What is new here is an all-electric fleet which is also interconnected with public transport.
