Mazda Road to 24 winner selected

The ‘Mazda Road To 24 Shootout’ gives the winning driver the chance to step up from amateur racing to a funded drive in the 2020 Global Mazda MX-5 Cup.

Last week at the Michelin Laurens Proving Ground in Mountville, South Carolina, six drivers competed for the $100,000 to compete in the 2020 Battery Tender Global Mazda MX-5 Cup presented by BFGoodrich.

From a deep field of drivers with varying backgrounds in amateur sports
car racing, Jared Thomas from North Vernon, Indiana was selected as the winner.
Thomas is a Senior at Indiana University Purdue University Indianapolis
majoring in Motorsport Engineering and represented his school in 2018 at the 61st
Annual Purdue Grand Prix, winning the event. Thomas has competed in Spec Miata
since 2017, with a highlight performance of second place at the 2019 NASA
Nationals at Mid-Ohio Sports Car Course.

Thomas will compete in the 2020 Global Mazda MX-5 Cup in the Soul Red
Crystal Global Mazda MX-5 Cup and will contend for the $75,000 Rookie of the
Year title.

“First and foremost, I just want to thank Mazda, Michelin and
BFGoodrich, and my competitors here today,” said Thomas. “This is definitely
one of the hardest things I’ve ever done in racing and something in my life
that I will always remember. I am able to share this with my Dad, who helped me
to build my Spec Miata and has been with me since the very beginning at age
five, gave me all of the opportunities and has been there at each step.

“Mazda really made sure in preparing for the Shootout that we had a
business plan, and they made us work really hard on it. So we we’ll stick with it,
work on it and continue to make …continue reading

Porsche developing next-generation quad-motor electric powertrain

Porsche Engineering have revealed they are working on a torque control system for a next generation four-motor all-wheel-drive electric SUV powertrain that provides maximum stability and safety in every situation—without additional sensors on board.

What makes a four-motor powertrain desirable isn’t so much more power, but more control. Each motor can be controlled individually and immediately, rather than relying on analogue mechanical differentials and inefficient hydraulic braking systems that don’t react as fast or as precisely. Solid state digital control is good for safety and stability in inclement weather and for improved performance and handling in dry weather. Basically, it’s the most high performance, responsive, adjustable and energy efficient torque-vectoring system possible.

An electric all-wheel-drive vehicle with multiple motors has a fundamental advantage over gasoline or diesel engines: The front and rear axles, indeed all four wheels, have their own electric motors, enabling extremely variable distribution of the drive power. “It’s almost as if you had a separate gas pedal for each axle or wheel,” explains Ulf Hintze of Porsche Engineering.

In a possibly related development, Porsche recently increased their ownership stake in Rimac to 15.5% following their 2018 investment for 10% of the business. Rimac developed a quad motor all-wheel-drive torque vector system for their Concept One hypercar.

The e-tron SUV concept unveiled by sister company Audi back in 2015 was originally intended to be powered by three electric motors. Unfortunately the dual motor rear eAxle didn’t make it into the production version.

Press Release:

Thanks to variably distributable drive power, electric vehicles with separately powered wheels can remain stable even in critical situations— as long as the torque control reliably detects deviations from the target state and reacts immediately. Porsche Engineering has developed and tested a solution for e-SUVs that does precisely that. Without additional …continue reading
