Over a decade after the P1 rocked the automotive world, McLaren has unveiled its latest hypercar, the W1. Like its successor, the W1 is a rear-wheel drive hybrid with a V-8 mounted within the center. But that doesn’t even come near telling the complete story. This is a much more superior automobile in each manner. Here’s what makes it so fascinating.
High-Downforce, Low-Drag Aerodynamics
So a lot of this automobile’s story is about aerodynamics, which is what you’d count on from an automaker tied to a Formula 1 workforce. McLaren quotes a most determine of two,205 kilos at 174 miles per hour, which is near the Aston Martin Valkyrie’s 2,425 kilos, and exceeds the McLaren Senna’s 1,800 kilos.
The Valkyrie is an fascinating level of comparability as a result of it’s the one different highway automobile that depends so closely on underbody, “ground effect” aerodynamics, reasonably than conventional over-body appendages. This helps maximize downforce with out including an excessive amount of drag, which might rob straight-line efficiency.
Various lively aerodynamic programs permit the W1 to succeed in a high velocity of 217 mph—the identical because the P1’s, although the W1 is able to producing way more downforce.
The entrance wing is lively, shifting in an arc so as to add or trim downforce on the entrance axle as wanted, whereas on the rear is what McLaren calls an “Active Long Tail” wing. Inspired by the long-tail bodywork of the 1997 F1 GTR race automobile, the rear bodywork can prolong by almost a foot to extend the effectiveness of the underbody diffuser.
Speaking of which, the diffuser has broad tunnels that begin curving up simply behind the cabin and in entrance of the rear axle. Like the Bugatti Tourbillon, the diffuser additionally acts as a rear bumper, robust sufficient to take severe impacts with out the necessity for a further (heavy) construction. Even the powertrain is angled down by 3 levels to permit extra room for diffuser channels.
There are different neat F1-esque particulars, for instance, the intakes formed just like the undercut aspect pods we’ve seen in F1 automobiles for just a few years now. The seats are mounted in place, serving to scale back frontal space, and as a substitute, the pedal field and wheel come towards the driving force. This means the driving force’s ft will likely be greater than their hips, as has been the case in F1 and sports-prototype race automobiles for a few years now.
F1-Inspired Suspension

Even the entrance suspension helps increase downforce and brake cooling. McLaren makes use of double wishbones, as you’d count on, nevertheless it additionally has pushrods, torsion-bar springs, and inboard dampers like an F1 automobile, shifting plenty of suspension elements out of the airflow. The wishbones and uprights are produced from 3D-printed titanium, and the decrease wishbones are mounted excessive up and formed like aerofoils, to contribute to the general downforce. There’s additionally a heave damper, one other racing-derived system, that helps stop the physique from decreasing an excessive amount of beneath load. There’s additionally no separate entrance subframe on the W1, with the suspension elements bolting on to the carbon-fiber chassis.
With a high-downforce automobile, you want a steady aerodynamic platform, and that comes from the suspension. Like the P1, the W1 has highway and race settings, the latter dropping trip peak by 1.46 inches on the entrance and 0.7 inches on the rear, and massively rising spring charges and damping drive.
The rear suspension is considerably extra standard, with conventional coilover springs over dampers, because the rear downforce is generated by the diffuser. By shifting these suspension elements additional outboard, McLaren can use wider, steeper, and subsequently simpler diffuser channels. However, McLaren additionally has what it calls “active drop-links” which work with a Z-shaped anti-roll bar to manage heave with out the necessity for a “third element” just like the heave damper on the entrance. We’ve requested McLaren for extra info on this explicit system. We additionally requested how, particularly, trip peak is adjusted.
A Brand-New Hybrid V-8

The trendy McLaren Automotive as we all know it has used a twin-turbo V-8 derived from a Nissan racing design courting again to the Eighties. With the W1, McLaren debuts its second in-house engine design after the 120-degree V-6 of the Artura, a twin-turbocharger 4.0-liter V-8 able to 916 horsepower and 664 pound-feet of torque, and a 9,200-rpm redline. For these holding observe at dwelling, that’s as a lot horsepower because the P1’s V-8 and hybrid system had mixed.
Naturally, there are neat particulars. Like plenty of the most recent ultra-high-performance combustion engines, the so-called MHP-8 makes use of finger followers to actuate the valve springs, reasonably than hydraulically actuated bucket-and-shim tappets, enabling higher-rpm efficiency. Unlike just about any engine we will consider, the V-8 eschews a metallic torsional damper for a fluid-damping system. Wild stuff, and we presume this helps save weight.
Unlike many different hybrid hypercars, the W1 solely sends energy to the rear wheels, and it does so through a brand new eight-speed dual-clutch transmission. And not like the Artura, the W1 has its electrical motor mounted to the aspect of the gearbox, working downstream of the 2 clutches. It’s powered by a 1.4-kilowatt-hour battery and makes 342 hp and 324 lb-ft by itself. Combined, you get 1,258 hp and 988 lb-ft.
The W1 has a really quick all-electric vary, however the electrical motor at all times handles reversing. It additionally provides completely different ranges of increase to the engine primarily based on the drive mode. A lift button on the steering wheel permits the driving force to deploy most energy suddenly.
Carbon-Fiber Sun Visors
McLaren
Ok, so this isn’t loopy high-tech like different components of the W1, however it’s neat. The solar visors are produced from carbon fiber, and are simply 0.1 inches thick. They’re there to remind you of McLaren’s consideration to saving weight. McLaren quotes a dry weight of three,048 kilos, so determine with all of the fluids vital for driving, the W1 weighs someplace round 3,300 kilos. Impressively mild for a hybrid with this stage of efficiency on faucet. Far lighter than the weights of the likes of the Valkyrie and Mercedes-AMG One, and hardly heavier than a 750S… which has 500 fewer horsepower and loads much less downforce.
There’s loads we nonetheless don’t know in regards to the W1, and we’re keen to listen to extra. After poring over the main points, the W1 appears to take plenty of the very best know-how and considering out there at present to maneuver the hypercar sport ahead. It could “only” have a bit over 300 hp greater than a P1, however this needs to be a a lot faster automobile.
A decade in the past, that may’ve been scarcely plausible, and albeit, it’s hardly plausible now.
