Recharge Wrap-up: Ford's "snowtonomous" Fusion Hybrid, Porsche eyes battery makers

Bosch and Panasonic are vying to be the battery supplier for Porsche's electric sports car based on the Mission E concept. While Bosch's costs may be higher, its solution would offer simpler logistics. Panasonic is already well established as a battery maker, providing the packs for the Porsche car's rival, Tesla. "We're in the final stage of making a decision," says Porsche CEO Oliver Blume, declining to comment on specific manufacturers. Neither Bosch nor Panasonic provided comment.

The project involves the installation of 1,000 EV chargers powered by 10,000 photovoltaic panels. The Renault Zoes would be used as part of a carsharing program powered by the solar chargers. Renault and its partners will also implement a vehicle-to-grid system to provide energy during peak demand from the solar chargers and connected EVs. Read more in the press release from Renault. Ford has been testing an autonomous Fusion Hybrid prototype that is capable of driving itself in snowy conditions. Ford uses 3D mapping to scan the drive route. Its LiDAR laser mapping can even detect single falling snowflakes. It collects and processes up to 600 gigabytes of data per hour, comparing its environment to saved maps, a process that helps establish location more precisely than GPS. In addition to the LiDAR systems, the car is also equipped with cameras and radar to help it navigate. Eventually, the car could even be able to clean off its sensors when it detects loss of performance from ice and dirt. Read more in the press release below. FROM AUTONOMY TO SNOWTONOMY: HOW FORD FUSION HYBRID AUTONOMOUS RESEARCH VEHICLE CAN NAVIGATE IN WINTER DEARBORN, Mich., March 10, 2016 – Driving in snow can be a slippery challenge, with the potential for one blizzardy gust to white-out your field of view – a situation faced by the majority of people in the United States. So if self-driving cars are to become a reality – and they almost certainly will – they must be able to navigate snow-covered roads. In its quest to bring self-driving vehicles to millions of people around the world, Ford reveals six facts about its technology that allows for a car to drive itself in snow. 1. Mapping the way: Ford first creates high-resolution 3D maps using LiDAR technology to scan the area its autonomous vehicle will later drive in the snow.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

2014 Porsche Panamera 4S Executive

If the idea of a Porsche sedan (or, long hatchback) is still off-putting to you, then you might want to look away now. For 2014, the polarizing Panamera has received a midcycle refresh bringing slightly different styling, as well as adding two new models to the lineup, the S E-Hybrid and the stretched-wheelbase Executive. Having focused most of my recent trip to Germany on a First Drive of the intriguing plug-in Panamera, I also got to spend some time with the roomier Executive model.
Offered in both 4S and Turbo guise, the Panamera Executive has been stretched by almost six inches for the sole purpose of improving rear passenger space. Although it's hard to imagine anyone would willingly buy a Porsche and opt to sit in the back seat, I'd have to say that if I'm going to be chauffeured around in a car, why not make it a Porsche? For the most part, though, I'm guessing that many Panamera Executive sedans will be owned by people who want to one-up their buddy driving a stretched BMW 7 Series or Mercedes-Benz S-Class.
