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:

In case you forgot, the Dubai Police supercar fleet is the coolest

Ever wonder why the Dubai Police have a fleet of vehicles worth millions and millions and millions of dollars? Why it has a Bugatti Veyron and a Bentley Continental and a Mercedes-Benz SLS AMG with sirens and light bars? Well, here's the reason. This video shows the fleet on display on the Emirate's roads and highways, while also reaching out to the people the police are meant to protect. It's an impressive display of machinery, to be sure. Alongside the Bentley, Bugatti and Mercedes, we spy a Ferrari FF, a Brabus G-Wagen, a BMW M6, a Nissan GT-R, an Audi R8 and a McLaren MP4-12C (although the latest Dubai Police car, the Lexus RC F, is absent). The video even has a very cinematic look and feel to it, which works well with the night scenes and the blues-and-twos of the exotics cruisers.

2020 McLaren GT Suspension Deep Dive | A grand tour underneath

This is not the first Suspension Deep Dive I’ve written that featured a McLaren. The last one happened just over 10 years ago, if you can believe it, after a colleague and I had the chance to photograph an early naked rolling chassis of the MP4-12C before it went on sale. But this McLaren GT came to me as a fully operational machine, which allowed me to scrutinize it in my own driveway. That meant using my own tools, of course, which was frankly nerve-wracking when it came time to lift it. But it wasnÂ’t as bad as IÂ’d feared, as the jack points (more like zones) were clearly marked with stickers that depicted a floor jack icon that looked encouragingly like my own aluminum race jack. WhatÂ’s more, IÂ’d recently bought soft rubber jack and jackstand pads meant for safely supporting vehicles such as this. Thing is, the GT sat so low that I couldnÂ’t slide my floor jack underneath without additional measures. In front, this simply meant raising the carÂ’s nose lift, which weÂ’ll see later. But the rear has no such system. To gain the needed clearance I had to drive this quarter-million-dollar GT up onto a 2x6 laid flat on a square of plywood as if I were leveling a motorhome to make the fridge work properly. Yes, really.   Even with the front wheel safely removed, the GTÂ’s huge carbon-ceramic brake rotor blocks most of the view and makes it hard to see much of anything else. The main exception is the top end of what looks like a somewhat familiar damper assembly.   Like the MP4-12C and 720S, the McLaren GTÂ’s shocks are inverted to minimize unsprung mass. The damperÂ’s narrow shaft (green arrow, and hidden by a protective telescopic boot) makes up the moving end at the bottom, while the more massive business end and its horizontally arrayed and electronically controlled damper valves (yellow) are fixed to the chassis at the top. The higher of the two lumps is the compression valve, the lower one is the rebound valve. The McLaren GT parts ways with the MP4-12C and 720S at this point in a big way. Those Super Series cars have a kinetic hydraulic roll stabilization system, in which transverse piping links the compression valve on this side to the rebound valve on the opposite side, and vice-versa. But here we see a traditional stabilizer bar (red) of the same sort as the 570GT and 570S, albeit with a different specification that befits the GTÂ’s role as, well, a GT.
