Recharge Wrap-up: Renault Zoe driving video, BYD Buses in Campinas

A new video shows drivers how to get the most range out of the Renault Zoe. By managing one's driving style, as we all know, one can minimize energy consumption. The Zoe's Econometer and R-Link screen give feedback about the rate of consumption, which helps let the driver know that they should hold back in the throttle. The R-Link system shows the distribution of energy in real time. It also analyzes the driving route and gives feedback at the end of the session. The Zoe also has an Eco button that automatically limits consumption regardless of driving style. Pre-programming climate control can also help improve range. These are all features we're more or less familiar with, but see how they work in the Renault Zoe in the video above. Tesla has announced it will release its second quarter results on August 5. After the automaker releases its financial information on that day, it will hold a live question and answer conference call webcast to discuss those results and outlook at 5:30 Eastern. The second quarter ended June 30. Read more at MarketWatch. Campinas, Brazil will add 10 BYD electric buses to its fleet. It is the first city in Brazil to have a zero-emissions bus fleet. Campinas will be using BYD's 39-foot, four-door K9 battery electric bus, but the K11 articulated electric bus will also begin testing in the city soon. Campinas Mayor Jonas Donizete likes the electric buses because "they are very comfortable, almost noise-free, and great for the environment," and they will help reduce the city's air and noise pollution. BYD plans to open factories for electric buses and solar panels in Campinas over the next year, investing about $108.5 million from 2014 to 2017. Read more in the press release below. BYD to Deliver 10 Electric Buses to Campinas Public Transport Fleet 07/22/2015 (Campinas, Brazil): BYD do Brasil and Campinas City Administration announced this month, the addition of 10 battery-electric buses to the city's public transportation bus fleet. Campinas is a city in the interior of the state of Sao Paulo, Brazil, and will be the first in the country to have a fleet of fully electric, zero emission buses operating in its streets. The model chosen to integrate the fleet in Campinas is the BYD K9, a 12-meter, 4-door, low-floor urban bus, with universal accessibility for passengers with limited mobility.

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.

Tesla working to eliminate side mirrors

Of all the concept car technologies, one of our favorites has been the deletion of side-view mirrors in favor of video cameras. Besides improving the look of the car, it'd lower drag and improve fuel economy. However, cost, available technology, and most importantly, the government, stand in the way of this tech making it onto a production model.
It's that last facet that Tesla is seeking to change. As Automotive News explains, when the Model X debuted in concept form, it was without wing mirrors. But when the production car was revealed, it had the conventional mirrors, largely because the camera'd car violated the National Highway Traffic Safety Administration's Federal Motor Vehicle Safety code (Standard 111, to be precise).
Now comes word that Tesla has actively been lobbying the NHTSA to do away with the standard. It's got breathing room at the moment. We reported a few months ago that the federal mandate regarding backup cameras had been pushed back to 2015. That gives Tesla plenty of time to work the safety administration over regarding the mirror replacement, getting the new tech approved in the next mandate.
