Bosch develops 48V electric powertrain for motorsport kart prototype with FIA and DMSB; new boost recuperation system

May 27, 2016

FIA Electric, the New Energy Commission, and the German Motorsport Association (DMSB) presented an electric racing kart prototype—the “e-kart”—in Berlin. Bosch Motorsport developed the powertrain system together with these motorsport organizing bodies, as well as with Germany’s largest kart manufacturer Mach 1 Kart.

For this application, Bosch motorsport engineers developed a new boost recuperation system (BRS), the first generation of which will go into production at the company starting in 2017. The electrical components of the BRS support the internal-combustion motor in compact vehicles with up to 10 kW of additional power, which reduces fuel consumption and CO2 emissions by up to 15% on the street. It also provides the internal combustion engine with an additional 150 N·m (111 lb-ft) of torque during acceleration.

NVIDIA DRIVE PX 2 platform to power world’s first robotic motor sports competition

April 06, 2016

At CES 2016 in January, NVIDIA introduced NVIDIA DRIVE PX 2—its new generation high-performance computing platform for in-vehicle artificial intelligence applied to the complexities inherent in autonomous driving. (Earlier post.) This week, at NVIDIA’s GPU Technology Conference, the company announced that the DRIVE PX 2 platform will be used in the cars that will compete in the Roborace Championship, the first global autonomous motor sports competition.

DRIVE PX 2—which delivers processing power equivalent to 150 MacBook Pros—uses two next-generation Tegra processors plus two next-generation discrete GPUs, based on the Pascal architecture (earlier post), to deliver up to 24 trillion deep learning operations per second. Deep learning operations are specialized instructions that accelerate the math used in deep learning network inference. That’s more than 10 times the computational horsepower than NVIDIA’s previous-generation DRIVE PX.

Toyota GAZOO Racing introduces TS050 hybrid racer for 2016 WEC season; moves up to 8MJ class with Li-ion battery

March 24, 2016

Toyota GAZOO Racing revealed the all-new TS050 HYBRID LMP1 racer—Toyota’s third new car since joining WEC in 2012—for the 2016 World Endurance Championship (WEC) competition. Following an unsuccessful defense of its World Championship titles in 2015, Toyota set itself tough performance targets in order to compete once again at the front of the field, featuring fellow LMP1-Hybrid manufacturers Porsche and Audi.

The TS050 HYBRID features a significant change in powertrain concept. A 2.4-liter, twin-turbo, direct injection V6 gasoline engine is combined with an 8MJ hybrid system, both of which are developed by Motor Sport Unit Development Division at Higashi-Fuji Technical Center.

Porsche presents new 919 Hybrid LMP1 racer; 800V battery technology

March 23, 2016

Two days before the official Prologue for the FIA World Endurance Championship (WEC) at Paul Ricard, France, Porsche presented its new 919 Hybrid LMP1 race car for the 2016 season.

This season, Porsche will fully exploit the WEC regulations by deploying three different aerodynamic packages to make the car best suited to the respective race tracks. (Three aerodynamic specifications are the maximum allowed.) The weight of the four-cylinder turbo engine, as well as its fuel consumption, was further reduced, while the efficiency of the two energy recovery systems of the hybrid drive have been improved. For 2016, the components of the electric drive have also become more powerful and efficient.

Audi unveils redesigned R18 diesel hybrid Le Mans racer for 2016 season

March 22, 2016

Audi unveiled its redesigned R18 diesel hybrid Le Mans racer for the 2016 World Endurance Championship (WEC) season. Among the new features in the R18 are a more radical aerodynamics concept, including a new safety cell; a Li-ion battery replacing the flywheel energy storage system; and a revised V6 TDI diesel engine. As a result, Audi’s LMP1 sports car is more powerful and more efficient than its predecessor; the new R18 consumes less fuel than any of the generations before it.

The new hybrid TDI powertrain delivers power output of more than 1,000 hp (746 kW), along with 10% less consumption that its immediate predecessor. The current V6 TDI consumes 32.4% less fuel than the first generation did in 2011.

New Audi R18 makes its debut; fundamental redesign of diesel hybrid racer with Li-ion battery storage

November 29, 2015

The new Audi R18 made its world premiere on the occasion of the Audi Sport Finale at the Audi Training Center Munich on Saturday. Audi Sport has fundamentally re-designed the Audi R18 for the 2016 season.

The LMP1 race car that will compete in the Le Mans 24 Hours and in the FIA World Endurance Championship (WEC) in 2016 features innovative aerodynamics; represents the next stage in lightweight design; and has a modified hybrid system with lithium-ion batteries for energy storage, plus an efficiency-optimized TDI engine. The 2015 R18 e-tron quattro racer featured an encapsulated WHP flywheel energy storage system that sat in the cockpit alongside the driver. (Earlier post.)

Qualcomm & Mercedes AMG Petronas F1 Team partner on racecar data sharing over 5 GHz 802.11ac Wi-Fi; planned migration to 802.11ad (WiGig)

October 24, 2015

Qualcomm Incorporated through its subsidiary, Qualcomm Technologies, Inc., and the Mercedes AMG Petronas Formula One Team, have collaborated to enable the wireless download of racecar telemetry data via Wi-Fi using 5 GHz spectrum during Formula One practice sessions. This technology implementation marks a significant improvement over previous wired data offloading processes. The telemetry includes data from thermal imaging tire cameras, which is used to improve speed, efficiency and vehicle safety.

The system deployed by the Mercedes AMG Petronas Formula One Team and Qualcomm Technologies comprises several Qualcomm Snapdragon 805 processors with Qualcomm VIVE 802.11ac Wi-Fi, along with multiple access points, one in the pit lane and one in the garage, to improve the speed of connectivity and data transfer.

Williams: Formula E battery power to increase to 170 kW for season two; 70 kWh pack for Evoque-E

September 11, 2015

Williams Advanced Engineering, the sole supplier of the battery packs for the FIA Formula E Championship, confirmed that the maximum power output of the batteries for the racers will increase to 170kW during each race in season two of the Championship.

The 28 kWh (maximum usable) battery packs, which use cells from XALT Energy (earlier post), were initially designed to meet season one technical specifications from the FIA and operated during a race at a maximum power of 133 kW. Following successful pre-season testing this was increased to 150kW for the start of season one to increase the performance of the cars.

Nissan to address KERS issues of GT-R LM NISMO before returning to FIA World Endurance Championship

August 07, 2015

Nissan will delay its return to the LM P1 class of the FIA World Endurance Championship and instead focus on technical issues that challenged its race team during the Le Mans 24 Hours in June. Issues with the kinetic energy recovery system (KERS) meant that the Nissan GT-R LM NISMO (earlier post) had to run at the Le Mans 24 Hours on engine power alone. The next race for the Nissan GT-R LM NISMO would have been the 6 Hours of Nürburgring, round four of the FIA World Endurance Championship, on 30 August.

The Nissan GT-R LM NISMO represents an innovative interpretation of the sport’s technical regulations: a front-engined, front-wheel-drive car that powered by a V6 3.0-liter twin turbo gasoline engine and a mechanical flywheel Energy Recovery System (ERS) that runs in the 2MJ class.
