Watch a vintage McLaren F1 car fall from the sky in Monaco

All hell broke loose during last week's Monaco Historic Grand Prix after a crane dropped a vintage racecar right in the middle of a track. During a race. Then things got worse. The track was already under a full-course yellow with a safety car when the corner workers unsuccessfully tried to hoist the already stricken McLaren M23 off the track at Mirabeau. But before they could communicate what had happened to the head marshals, the safety car was back in pit lane and the field was moving up to speed. What happened next could best be described as chaos. In the coverage from Motors TV, you can just barely see the Renault Megane safety car rampaging through the pits trying to intercept the field of vintage F1 cars before they make the turn at Sainte Devote. It's ultimately unsuccessful, which leads to the bizarre sight of a bright yellow French hatchback trying to slice through a field of priceless cars on one of the tightest, most difficult tracks on the F1 calendar. The drivers, getting frantic communications from the pits about the danger at Mirabeau, do their best to slow down and get out of the Megane's way. An Avon slows a little too quickly and gets whacked by a lovely Tyrell. Like we said, chaos. Check out the action up top.

One of only two McLaren F1s in LM-Specification headed for auction in Monterey

Of all the McLaren F1s out there (106 of them, including racecars and other variants), this 1994 F1 in LM-Specification is about as special as they get. Incredibly, it’s going up for auction in Monterey at the RM SothebyÂ’s auction house during Monterey Car Week. Why a McLaren F1 owner would ever want to sell their car is beyond us, but weÂ’re sure the millions of dollars on the other side of the gavel look pretty alright. This F1 happens to be one of two in existence in LM-Specification. In case you werenÂ’t familiar with the model, McLaren upgraded two standard F1 road cars to this particular specification at the factory after the production run had finished. That means the engine was upgraded to the unrestricted 680-horsepower GTR spec. An extra-high downforce kit was also added, consisting of a huge rear wing, revised nose and different front fender vents. Other differences between this and a normal F1 include race-spec dampers and springs adjusted to their softest settings, 17-inch wheels, a transmission cooler, two more radiators and a modified exhaust system. What it doesnÂ’t have is the barren interior from the hardcore LM. Instead, McLaren gave it an upgraded air conditioning system, radio, new headlights and a different steering wheel. That means you have the more aggressive performance with a slightly more comfortable living space, a combination we like. McLaren says it made all these changes over two rounds of modifications in 2000 and 2001. The car was also repainted from its original blue to the silver you see now in that timeframe.  This particular F1 has 13,352 miles on the odometer, and it has been given a full written history and evaluation by MSO. WeÂ’re sure itÂ’s going to nab many millions of dollars. To whoever ends up purchasing this fine McLaren, we envy you greatly.

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:
