Karma shows 3 plug-in vehicles at Shanghai auto show

California-based Karma Automotive presented 3 new vehicles
at the recent Shanghai auto show. Karma’s “Shanghai Big Three” are: the 2020
Karma Revero GT, a PHEV that features a BMW three-cylinder in-line gas engine;
the Karma Pininfarina GT coupe, a version of the Revero GT with a new body
style, panels and interior designed by Italian design house Pininfarina; and the
Karma SC1 Vision Concept, a fully electric roadster.

“This is the first major auto presence for Karma in China, and marks a significant moment by ushering in a new era for the company,” said Karma CEO Dr. Lance Zhou.

Karma, which was salvaged from the former Fisker in 2014 by
the Wanxiang Group, now employs nearly 1,000 people at four sites in
California, Michigan and Hangzhou, China.

Dr. Zhou explained the company’s “open-platform” philosophy: “We will use partnerships with like-minded collaborators to accelerate our progress by acquiring and developing key technologies important to connectivity, performance, artificial intelligence, shared mobility platforms and electrification. Partners can use our product platform as an incubator to test and prove their new innovations, and likewise, our engineering and design resources can be offered to help other partners advance their needs.”

Tesla investor provides a look inside new Roadster

2020 Tesla RoadsterAt Tesla’s self-driving event for investors on Monday afternoon, the company revealed another tidbit: a glimpse of its upcoming second-generation Roadster. The company parked the new Roadster at the event, and for the first time let outsiders (at least those who have invested significant sums) open the doors and sit in it. The prototype was not…

Tesla unlocks even more power (150 kW) out of existing Superchargers, expands rollout

At the launch of Supercharger V3 earlier this year, Tesla announced that it will also unlock more power in existing Supercharger stations (from 120 kW to 145 kW).

Tesla confirms today that it will actually be able to push the power output even higher (150 kW) and it started expanding the rollout of other charging features announced at the event. more…

Lots of news to digest as Tesla demos latest Autopilot system

At the recent Autonomy Investor Day, Tesla highlighted the
progress it’s been making on its Autopilot system, and discussed its vision for
the future of self-driving. Elon Musk and several other company execs,
including Director Peter Bannon, Senior Director of Artificial Intelligence
Andrej Karpathy, and VP of Engineering Stuart Bowers, made presentations for an
audience of key investors, some of whom also got to test-drive (or test-ride) a
prototype of the latest tech.

Visually-oriented folks can watch the entire presentation, which runs nearly four hours, or a short summary provided by Tech Insider.

Tesla has not yet delivered the promised coast-to-coast driverless drive, but it did release a video showing a Model 3 driving on a mix of highways and local roads around Tesla’s Palo Alto headquarters, with no human hands on the wheel.

Much of the day’s news had to do with the Tesla Full
Self-Driving (FSD) computer (formerly known as the Autopilot 3.0 upgrade), the
brain of the new system, which is now included in all Teslas being produced. Tesla
designed the FSD computer solely for self-driving tasks, and limited power
consumption to 100 watts to avoid impacting the vehicle’s range. It includes
two totally redundant systems on a single circuit board – if any aspect of the
system fails, Musk says, the car will keep driving.

Noting that automaker Tesla has never before designed its
own chip, Musk claims that the FSD is “the best chip in the world…by a huge
margin.”

Competitor NVIDIA quickly disputed that claim. “NVIDIA is
the standard Musk compares Tesla to – we’re the only other company framing this
problem in terms of trillions of operations per second, or TOPS,” wrote NVIDIA VP
of Autonomous Machines Rob Csongor in a
blog post
. “But while we agree with him on the big picture – that this is a
challenge that can only be tackled with supercomputer-class systems – there are
a few inaccuracies in Tesla’s Autonomy Day presentation.”

“Tesla’s two-chip FSD computer at 144 TOPs would compare against the NVIDIA DRIVE AGX Pegasus computer which runs at 320 TOPS for AI perception, localization and path planning,” Csongor writes. “Additionally, while [NVIDIA’s] Xavier delivers 30 TOPS of processing, Tesla erroneously stated that it delivers 21 TOPS.”

Noting that self-driving will require “massive amounts of
computing performance,” Csongor concedes that Tesla has raised the bar. “Every
other automaker will need to deliver this level of performance. There are only
two places where you can get that AI computing horsepower: NVIDIA and Tesla. And
only one of these is an open platform that’s available for the industry to
build on.”

Tesla’s latest Autopilot hardware suite includes 8 cameras,
12 ultrasonic sensors, radar, GPS, an inertial measurement unit, and sensors
that measure the angle of the steering wheel and accelerator pedal.

One feature it does not have is lidar, a technology that uses
pulsed laser light to measure distance to a target, and that is favored by most
other companies that are working on autonomous driving. In his presentation,
the ever-iconoclastic Musk dismissed lidar in terms reminiscent of those he has
used to describe hydrogen fuel cells. Lidar is “a fool’s errand,” he said. It’s
“expensive” and “unnecessary,” and “anyone relying on lidar is doomed.”

Some autonomy experts agree with Musk. Gizmodo reports that Cornell researchers argue in an upcoming paper that a pair of cheap cameras mounted behind a vehicle’s windshield can produce stereoscopic images that can be converted to 3D data almost as precise as that generated by lidar, at a fraction of the cost.

Above all, Tesla is relying on the vast neural network of real-world driving information recorded by the thousands of Autopilot-equipped Tesla vehicles on the road. Using various AI techniques, Tesla is teaching its system to recognize and react to the vast variety of situations that might be encountered in the wild.
