McLaren EV supercar: Here's the math that says it's 5-10 years off

It emerged last December that McLaren had built an all-electric testbed for a future EV supercar, to go along with the English automaker's $1.4 billion investment in electrified powertrains. But as we told you a few weeks ago, McLaren CEO Mike Flewitt said that such a car was, as a practical matter, years away from production. Now COO Jens Ludmann has put some numbers to the carmaker's quest, saying, "[The] Senna has 800 PS [Pferdestarke] on 1,200 kg, that's about the power to weight that we're looking for." He's talking about 789 horsepower in a package lighter than a base Honda Civic Coupe. The issue isn't energy capacity, it's energy density. Said Ludmann, "[The] battery technology should achieve 500 watt-hours per kilogram. That is a level where it really makes sense. Today we are around 180 watt-hours per kilogram." McLaren Engineering provides batteries for Formula E rated at 216 Wh/kg, but those packs aren't suitable for a consumer road car. According to what the company's learned from the battery industry, we're 5 to 10 years away from 500 watt-hours per kilogram for a roadworthy vehicle. In 2015 Rimac unveiled a battery it made for the Koenigsegg Regera. Said to be the most energy-dense car battery at the time, it boasted a power-to-weigh ratio of 60 Wh/kg. Figure that the battery industry's adding 40 Wh/kg per year — which gets us from 2015 to Ludmann's 180 Wh/kg current state of affairs. Using that measure, we're 8-10 years away from 500 Wh. McLaren wants its theoretical EV owner to be able to do 30 minutes or 10 hard laps at the track, be "as exciting as a 675LT," and recharge in 30 minutes for another half-hour track session. That battery would need exceptionally high energy density, and the cells and electronics would need to stand up to constant high power output and extreme discharge cycles. To enable that with today's battery tech, you'd end up with a vehicle that could do 500 miles in everyday road use, be far too heavy for McLaren's aims, and take far too long to charge. Ludmann told Wheels magazine everything else about the EV supercar is "all resolved — easy." While we dig in for what could be a lengthy wait, we'll have to be satisfied with the McLaren hybrids that should start showing up in a couple of years. Related Video:

McLaren reveals top-exit exhaust of new model, announces launch date

McLaren just released some more tidbits of info about its next car, including a new teaser image. This one explains the lack of the exhaust in the last photo: The exhaust comes out of the top of the engine cover. Two big outlets sit at the back and center of the engine cover, and it looks like they're just ahead of the retractable rear spoiler. They certainly look cool, probably sound cool, and we wouldn't be surprised if there's a performance reason behind this placement. Besides the sneak peek at the exhaust, McLaren made a few broad statements about the car. It said that it will be more powerful and lighter than whatever it's based on.The company also indicated earlier that the car will be very hardcore and uncompromised. From the previous teaser, we're fairly certain the car is based on the Sports Series McLarens that include the 570S, 570GT and 570S Spyder in the U.S., and the 540C in other markets. Since the names of the cars are based on horsepower, and this one will make more than the current 570 models, it probably won't use the 570 moniker. We also won't have to wait too long to see the car revealed. The company will show it off on June 28 at 7 a.m. Eastern time. We'll then get to see it in action when it heads up the hill at Goodwood Festival of Speed on July 12. Related Video: This content is hosted by a third party.

Ferrari, BMW lend expertise to Olympic bobsled, skeleton, luge

LONDON — There are plenty of reasons why the sport of bobsleigh is sometimes referred to as Formula One on ice, but few as obvious as Italy's World Cup sleds. Resplendent in Ferrari red, and with a set of team sponsor Pirelli's P-Zero tyres painted on the sides, they are even liveried to look like racing cars. Ferrari, Formula One's most glamorous and successful team, have worked with the Italian federation, whose sleds run without sponsor branding at the Olympics, since 2010 and in the run-up to next month's Pyeongchang Winter Games. Former rival BMW, title sponsor of the World Cup, has long partnered the U.S. bobsleigh team, while McLaren teamed up with Britain's bob and skeleton athletes for the 2014 Sochi Games in Russia. "There's always the link between the Formula One companies, or any motor company, and skeleton and bobsleigh," says Rachel Blackburn, the engineer who has been involved in Britain's skeleton program since 2006 and who used to work for McLaren. "There's the Ferrari sleds and the BMW sleds ... when we were at McLaren it kind of made a good story," she told Reuters by telephone from her home in Dubai. That somewhat manufactured rivalry has died down in the years since Sochi, with McLaren no longer involved and Ferrari's presence low key. But the worlds of grand prix motor racing and sliding sports still have plenty in common. Bobsled, luge and skeleton are among the fastest of Olympic sports, with bobsleds reaching speeds over 90 mph. Drivers are subjected to gut-wrenching G-forces, and crashes can be fatal. And then there is the ongoing debate about cost controls, the direction of future rules, preserving a level playing field and obsessive secrecy — all endlessly recurring themes in Formula One. 80 mph on a tea tray Blackburn said skeleton, where riders hit 80 mph on what has glibly been compared to an oversized tea-tray, sits somewhere between Americas Cup yachts and Formula One cars in terms of speed and aerodynamics. "Applied engineering is far more interesting than the pure stuff, so when its applied to something that's fun and exciting it does make it a lot easier to solve problems," she said. "There is the Americas Cup, sailing, Formula One and the high speed ice sports as well. It's the same concept.
