Mercedes F1 boss Toto Wolff takes a stake in Aston Martin

LONDON — Mercedes Formula One boss Toto Wolff has taken a stake in British sportscar maker Aston Martin, whose executive chairman Lawrence Stroll runs the Racing Point F1 team, according to company filings. A Mercedes F1 spokesman said Wolff's move was purely an investment on the Austrian's part and would be diluted by a rights issue on Monday from 4.77% to less than 1%. "Fully diluted following the pending rights issue, this investment will represent a 0.95% stake in the company," he added. "It is a financial investment and Toto's partnership and executive role with Mercedes are unaffected by the transaction." Swiss billionaire Ernesto Bertarelli has also bought a 3.38% stake which will be similarly diluted. Wolff previously had a 16% shareholding in former champions Williams but sold that after he joined the Mercedes team, where he serves as principal and owns 30%. Canadian billionaire Stroll, whose son Lance drives for Racing Point alongside Mexican Sergio Perez, is close to Wolff. The Silverstone-based team — to be renamed Aston Martin next year — use Mercedes engines and gearboxes. Mercedes-Benz's parent Daimler also has a small stake in Aston Martin. "It's clear that Aston are now Mercedes' B team," the Daily Mail quoted one Formula One insider as saying. Wolff's future at Mercedes has been the subject of some media speculation, with the 48-year-old linked variously to senior management roles with Liberty Media-owned Formula One and at Aston Martin. His Aston Martin shares were bought from Yew Tree Overseas Limited, a vehicle controlled by Stroll who acquired a roughly 25% percent holding in Aston Martin with a consortium of investors. Mercedes have won the past six Formula One drivers' and constructors' titles but have six times world champion Lewis Hamilton out of contract at the end of the 2020 season, which has yet to start due to the COVID-19 pandemic. Hamilton, who has also been linked to Ferrari, had told reporters before the global crisis changed the sporting and financial landscape that his decision would depend on Wolff's plans. The Briton is now expected to stay at Mercedes, with a radical overhaul of Formula One's sporting and technical regulations postponed to 2022. Related Video: Motorsports Aston Martin Mercedes-Benz

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

Recharge Wrap-up: Mercedes gets F1 efficiency, EV charging in Vermont, VW e-Golf to use Bosch

Efficiency equals performance, especially in the case of Formula 1 racing. The Mercedes AMC Petronas team points to several key efficiency technologies it uses to get the most out of its cars. And if their utter dominance so far this season is testament to this relationship, perhaps we should pay attention. Mercedes highlights hybrid tech, turbocharging, aerodynamics, lightweight construction, tribology (both in making internal components and lubricants more slippery) and simulation as crucial to getting around the track faster than anyone else. These just happen to be some of the same things that make the cars we drive on public roads more fuel-efficient. Learn more in the press release below. It's a good read. Brammo, maker of sweet electric motorcycles, is teaming up with TEAM Industries to make drivetrains for electric vehicles. TEAM, which specializes in drivetrain technology, will also become an investor in Brammo as part of the partnership. "The electric vehicle market is a growth market," says TEAM CEO and President David Ricke, "and TEAM and Brammo will be providing a wide range of solutions for OEM manufacturers." Read more over at EV World. Vermont celebrated the installation of a new EV charging station as part of a Green Energy Corridor between Boston and Montreal. When finished, drivers will be able to make the whole trip in an EV with access to charging along the way. For $5, customers can charge their vehicle in about 30 minutes at the Red Hen Baking Company in Middlesex. There are currently only about 700 EVs on the road in Vermont. The state has a goal to get 90 percent of its energy from renewable sources by 2050, and getting more EVs on the road is crucial to that mission. Vermont hopes that expanding the charging infrastructure will convince more people to go electric. Read more at Vermont Public Radio's website. For it's new e-Golf, Volkswagen will use Bosch chargers for home installation and ChargePoint stations at its dealerships. Bosch will have various 240-volt options for the home, and will also provide installation. e-Golf customers will also get a free ChargePoint membership, and will have access to the company's network of charging stations worldwide. The 2015 e-Golf goes on sale in the US later this year. Read more in the press release below.
