Porsche suspends ties with Maria Sharapova after drug test

Porsche has reportedly suspended ties with Maria Sharapova after the Russian tennis star failed a drug test. The German automaker stopped short of terminating its relationship with the athlete altogether as it awaits the results of a deeper investigation. The issue emerged at the Australian Open, where Sharapova reportedly tested positive for use of a drug called meldonium. Manufactured in Latvia and prescribed in many former Soviet Bloc countries, meldonium is used to treat heart conditions and improve cardiac circulation. It is not approved by the FDA for use in the United States, and the World Anti-Doping Agency added it to its list of prohibited substances at the start of this year. Sharapova admitted that she's been taking the medication for ten years now but that she did not keep up to date on the WADA's list. Since it is considered a prohibited substance, she's been excluded from participating in the Australian Open this year, and suspended from competition as of March 12. She was also scheduled to take part in the Porsche Grand Prix, a tennis event sponsored by the carmaker in Stuttgart next month which she will now apparently have to miss. One of the top-rated female tennis players in the world, Sharapova has served as a brand ambassador for Porsche since 2013. Other sponsors including TAG Heuer and Nike have also reportedly suspended their relationships with the athlete pending further investigation by the International Tennis Federation. Related Video:

Ruf RGT 4.2 offers 518 hp of naturally aspirated power

Ruf has a reputation for building some fast interpretations of the Porsche 911, and the company's latest RGT 4.2 at the Geneva Motor Show provides an interesting point of comparison compared to the new GT3 RS that's debuting there. In terms of pure power, the Ruf wins out. The company crafts a flat six with 4.2-liters of displacement making 518 horsepower and 369 pound-feet of torque with a top speed of 200 miles per hour. In contrast, the latest GT3 RS gets 500 ponies and 338 lb-ft of twist from its direct-injected 4.0-liter mill. Depending on your desires, the RGT 4.2 might have the preferred gearbox too with its six-speed manual versus the Porsche's PDK. Styling is also going to come down to personal tastes between these two. The RGT 4.2 has an almost old-school racing look with its bolted-on fender flares, five-spoke wheels, thick carbon fiber rear wing and lower front air dam. Inside, there's also an integrated roll cage. The RS, on the contrary, appears thoroughly modern with its big fender intakes at the back, slashes just behind the front wheels, CFRP hood and magnesium roof. Check out Ruf's naturally aspirated monster on the Geneva show floor in the gallery, above. The RGT 4.2 maintains a long tradition of Ruf supercars with its outrageous driving performance. Unveiled in 2000, the first RGT was characterised by its powerful, torquey normally-aspirated flat-six engine. With a significantly reduced all-up weight and sports-oriented suspension system, the RGT was an extremely impressive driving machine.Now, in 2015, the RGT remains true its original concept, though its external appearance is clearly more athletic. The wheel arches are more bulbous and the front facade presents huge round air intakes for more effective cooling. The chassis is reinforced by RUF's hallmark Integrated Roll Cage (IRC). Propulsion is provided by its virile 4.2-litre six-cylinder, normally-aspirated engine, developing 525bhp and 500Nm of torque, featuring dry sump lubrication with external oil tank.

Audi's Project Artemis woes could delay range of VW Group EVs

Two years ago, Audi's then new CEO Markus Duesmann announced his first big initiative called Project Artemis. The plan's marquee component is "to implement a new lighthouse project for Audi in record time," being "a highly efficient electric car scheduled to be on the road as early as 2024" on a brand new platform that would be shared with Porsche and Bentley. An ex-VW and -Porsche man named Alex Hitzinger, who'd also spent time at Apple working on the tech company's electric car, was brought on board to lead Project Artemis and come up with new ideas. Parent Volkswagen Group said it wanted to become "as agile as in a racing team," removing the bureaucratic molasses and bottlenecks interfering with getting the best product on the road in the best time. However, in any grand venture, failure comes before success. Automobilwoche reports that Artemis is struggling through issues large enough to push the product plans back by years. The issue, as it was with the ID.3 lineup on the eve of that car's launch, is software. Well, that's the latest, largest problem; Artemis has already been through copious struggles before getting to the software bit. Two months after Hitzinger came on, in December 2020, VW raised its EV volume target from 50% to 70% by 2030. That necessitated a rethink of the VW Group's entire platform strategy considering the far greater production scale. Hitzinger only lasted six months in the job, ousted in May 2021, supposedly because Audi believed his ideas were "not suitable for profitable series production" among other reasons. By that time, the pace of software development was already said to be six months behind schedule, with the Car.Software division working on VW.OS 2.0 "not yet running at the speed hoped for." Internal frictions were noteworthy and costly as well. VW's commercial division plant in Hanover was meant to build Artemis vehicles for Audi, Porsche and Bentley, but Automobilwoche reported in January of this year that Porsche paid a ""small three-digit million amount" — like $100 million or so — to get out of the deal mandating its vehicles come from the Hanover facility.    So Audi effectively brought Artemis in-house to lead vehicle development, and Car.Software turned into Cariad to get VW.OS and VW.AC, which stands for Automotive Cloud, to market.  The first Audi vehicle under Project Artemis was planned to arrive by the end of 2024, a production version of the Grandsphere concept.
