McLaren's chief test driver, Kenny Brack, has taken the McLaren Hyper-GT prototype up to 250 mph at Kennedy Space Center in Cape Canaveral, Florida.

The Speedtail prototype has undergone its final high-speed testing as part of its development and validation process. The car, nicknamed "XP2" reached that 250 mph maximum speed over 30 times on the space shuttle landing runway at the Johnny Bohmer Proving Grounds. Other test facilities where the feat was achieved include Idiada in Spain and Papenburg in Germany.

"It's fitting that the Speedtail's high-speed test program concluded with multiple maximum-speed runs at a location so strongly associated with pushing the boundaries of extreme performance and engineering excellence," said Mike Flewitt, CEO, McLaren Automotive. "The Speedtail is a truly extraordinary car that epitomizes McLaren's pioneering spirit and perfectly illustrates our determination to continue to set new benchmarks for supercar and hypercar performance."

XP2 is 17-feet long and made of carbon fiber, It's a three-seater and has the lowest aerodynamic drag coefficient of any vehicle McLaren has ever produced. The lower the drag coefficient, the better the vehicle is able to slip through the air, allowing it to be more efficient with its power usage.

The model is powered by a gas-electric hybrid powertrain that delivers more horsepower and torque than any McLaren road-worthy vehicle to date. It can get from zero to 186 mph in less than 13 seconds thanks to its 1,055 horsepower and 848 pound-feet of torque.

The car's battery pack has a density of 5.2 kW/kg making it the best power-to-weight ratio of any automotive high voltage battery system. Like a traditional hybrid powertrain, the batteries recharge as the vehicle is driven. However, the battery can also be trickle charged via a wireless charging pad. This pad is standard equipment with the production model and allows the car to stay charged even when it's not in use.

The first customer-ready models of the 106 McLaren Speedtails that will be hand-assembled at the McLaren Production Centre in Woking, England. They will be assembled to order and deliveries will be scheduled starting in February 2020.

All of the Speedtails have already been sold. The asking price? Right around $2.1 million each.

The IIHS may increase the speeds it uses to test advanced driver aids.

Insurance Institute for Highway Safety

The Insurance Institute for Highway Safety (IIHS) recently announced that it is considering changing the speeds it uses to test vehicle-to-vehicle front crash prevention systems. The agency currently tests the systems at 12 and 25 mph, but says that the speeds don't accurately represent the types of crashes the safety tech is meant to prevent.

Automatic emergency braking (AEB) is designed to notify of a possible collision and help respond with automatic application of braking. Just like a human using the brake pedal, it can stop the car, but higher speeds make it difficult to stop in time. The new tests would be conducted at 35 to 45 mph, which is the range where a large number of rear-end crashes occur. As Automotive News noted, an IIHS study showed 43 percent of rear-end crashes occur at speeds of 45 mph or less, so it's important to have a test that shows how well the tech performs at those levels.

A whopping 85 percent of 2022 vehicles earned a "Superior" rating in the current testing regime, so the IIHS will remove it from 2023 testing and Top Safety Pick award evaluations. Their view is that, since the majority of vehicles meet the criteria, it's no longer an accurate way of evaluating performance. In its place, the agency introduced a night test for automatic emergency braking systems that will begin next year.

The Z06 isn't on sale yet, but it's already raising money for charities.

Chevrolet

Just a couple years ago, the Chevrolet Corvette got a major overhaul that completely changed its design, personality, and performance. The car moved to a mid-engine layout for the first time, and its V8 produces thundering performance at a reasonable price. As it has always done with the Corvette, Chevy's laying out special editions for the car, and one of the first in the new generation will be the 2023 Corvette Z06. An early Z06 sold at a Barrett-Jackson auction this weekend to raise money for charity, and the final dollar amount crested the $1 million mark.

The car crossed the block at the Palm Beach Auction, which took place on April 9. It's the first production model of the car, which builds on the mid-engine eighth-generation Corvette. It's powered by a 670-horsepower 5.5-liter flat plane-crank V8, which sends its power to the rear wheels through an eight-speed dual-clutch automatic transmission. The engine revs much higher than a standard V8 and features a distinct sound. Chevy says the Z06's engine offers the most horsepower of any naturally aspirated V8 on sale.

The car's $1 million price tag raised money for the Thurgood Marshall College Fund. The organization supports training of educators at Historically Black Colleges and Universities (HBCU) and Predominantly Black Institutions (PBI). This auction, together with the first retail version of the car auctioned earlier this year, brings the Corvette's total charity haul to $4.6 million in 2022.
