The inside story on why McLaren will make an F1 successor

While official details are still few and far between, Flewitt confirmed the BP23 will be the fastest, most powerful car McLaren has ever built. McLaren's car-building division is keeping busy these days. It introduced the brand-new 720S during the Geneva Motor Show and its research and development department is currently working on no less than nine vehicle programs. Company CEO Mike Flewitt reiterated one of them is a long-awaited (and oft-rumored) supercar with three seats. Codenamed BP23 internally, the model will join McLaren's Ultimate Series lineup as an homage to the emblematic F1, the brand's very first road-going model. Flewitt explained the project started out as a one-off model commissioned by a collector and designed by McLaren Special Operations (MSO), a skunkworks team in charge of turning money-no-object customers' wildest dreams into road-going realities. It's difficult to keep a secret in the auto industry, especially when it comes to high-end cars, so news of a modern-day three-seater quickly spread outside of the company's headquarters in Woking, England. McLaren soon received an order for a second, identical car, and MSO agreed to build it. The orders kept pouring in. Production was bumped to 12 examples, up again to 46 to meet considerable demand, and finally capped at 106. The number was chosen because precisely 106 examples of the BMW-powered F1 were built from 1992 to 1998.

It won't feature aggressive-looking spoilers, splitters, and big wings; instead, it will boast a fluid, streamlined design fine-tuned to achieve the lowest possible drag. All 106 examples will be coupes, and a convertible model has been categorically ruled out. The only technical information currently available is that power will come from a V8-electric hybrid drivetrain. However, Flewitt noted the BP23 is not being developed with racing in mind, so McLaren won't offer a track-oriented, GTR-badged version of the car like it did with the F1 and, later, the P1. Expect a luxurious, well-appointed cabin in which the driver sits front and center, and two passengers travel in individual back seats. The extensive use of carbon fiber will keep weight in check. The BP23 – a name that most likely won't be retained on the final model – is scheduled to enter production in 2019.

More details on Lanzante's F1-engined Porsche 930 restomod

Not long after last year's Porsche Rennsport Reunion, we posted on Lanzante Engineering's restomod project with the original Porsche 911 Turbo. McLaren Formula One used TAG-branded Porsche engines for four years in the 1980s to win two constructor's and three driver's championships. McLaren sold 11 of those engines to Lanzante — nine of which have been raced, one with a win to its credit — and Lanzante is installing them into the original chassis of some 930s. PistonHeads stopped by the shop to find out more. By the end of its service in the MP4/3, the TAG-Porsche TTE P01 motor rang up 1,060 horsepower in qualifying and 960 hp in the race, revving to a 12,600-rpm redline. Porsche engine legend Hans Mezger had led the development, coaxing those numbers from just 1.5-liters of V6 aided by two large KKK turbos at a max of four bar. All that was fine for a time when F1 ran with unlimited testing and unlimited parts, but a modern owner doesn't want to pay five techs to live in his garage and keep his car running. Lanzante asked Cosworth to make the engine more drivable and reliable. Cosworth installed a new crankcase, adjusted the air-fuel mixture, and installed smaller turbos for quicker power delivery, decreasing max boost by 25 percent to three bar (43 psi). The redline has come down to 9,000 rpm, for final output figures of 503 hp and 310 pound-feet of torque. According to PistonHeads, power climbs a "steady incline to redline," and more than half the rev band delivers maximum torque. The 503-hp rating doesn't sound like much today, when a Mustang gets more than 700 hp. Yet the first 930 Turbos got 296 hp and 243 lb-ft from a 3.0-liter flat-six with one big KKK turbo. The most powerful 930 Flatnose worked up 330 hp and 347 lb-ft from a 3.3-liter flat-six. Lanzante's taken out a ton of weight, though. The TAG engine is already 220 pounds lighter than the 930's 3.3-liter; a new carbon fiber hood and engine cover, and aluminum door skins shed more pounds. The total package weighs roughly 2,430 pounds, which is more than 500 pounds lighter than the original Porsche Turbo. That includes the extra pieces needed to make an F1 engine power a passenger car. Lanzante had to swap in a 930 Flatnose front bumper, which replaces the fog lights for oil coolers. The team put radiators at the front of the car as part of a brand new water cooling system. The climate control is entirely electric, because F1 cars didn't come with HVAC.
