Here’s how Gordon Murray’s track-focused T50s can drive upside down

Many automakers have claimed that their supercars produce enough downforce to drive upside down, but in a new video Engineering Explained’s Jason Fenske shows how Gordon Murray’s T50s might be the first car actually capable of pulling the stunt off.

The T50s is the track-only version of the recently-unveiled T50 supercar. Like the road-going version, the T50s has a rear-mounted fan inspired by Murray’s Brabham BT46B “Fan Car” Formula One racer. But while the T50 has six modes for this fan, the T50s only has one—high downforce.

In the T50s, the fan spins at a constant 7,000 rpm to continuously generate that downforce. The car gets a number of other aerodynamic add-ons as well, including a roof scoop that works as a ram-air intake for the engine, a stabilizing fin like the ones used on Le Mans prototypes, and a large rear spoiler.

How does that allow the T50s to drive upside down? In order for that to happen, the downforce needs to cancel out the force of gravity, preventing the car from falling. The T50s might have enough downforce for that, and it can run at the sustained high speeds needed to continue generating that downforce, Fenske said, adding that Car and Driver estimated a top speed of 210 mph would be required.

At 210 mph, the T50s should behave like a regular car driven at average speeds, but only as long as it’s driven at a steady speed in a straight line, Fenske said. Any braking or steering would upset the balance needed to keep the car upside down. Driving upside down would also require changes to the oil and fuel systems, which aren’t designed to work inverted, Fenske noted.

Watch the full video for more details on the T50s and its downforce-generating abilities. In addition to more aero aids, the T50s gets a more powerful version of the T50 road car’s 3.9-liter Cosworth V-12, with 690 horsepower (or 720 hp with ram air). However, it also swaps the road car’s manual transmission for a paddle-shifted gearbox. Just 25 cars will be built, priced at $3.6 million each. Production is scheduled to start in 2023, or a year after the road car.

Ferrari Portofino M, Nissan Z Proto, Engler FF: This Week’s Top Photos

Ferrari’s Portofino was transformed into the Portofino M this week. The transformation included the addition of an 8-speed dual-clutch transmission and some extra horsepower, with the new mechanicals basically lifted out of the Roma.

Another upcoming vehicle spotted testing was the next 911 GT3 based on the 992 generation of Porsche’s sports car icon. The latest shots show the new GT3 testing alongside its predecessor, providing an excellent contrast between the two designs.

Nissan is working on a redesign for its Z sports car, the long-awaited Z35 generation. It’s expected to arrive in 2022 as a 2023 model and Nissan gaven us a preview this week with the Z Proto.

Engler FF

A company in the United Kingdom unveiled a quad bike powered by a 1,100-horsepower V-10. If you’re brave enough to push it to the limit, you’ll be able to rocket to 62 mph from rest in 2.5 seconds and keep accelerating until you reach over 217 mph.

A vehicle with similar performance to the Engler is McLaren’s Senna GTR. Five lucky customers will soon take delivery of an extra-special version packing more power and a bespoke, hand-painted livery. The individual liveries each pay homage to one of the five F1 GTR race cars that competed at the 1995 24 Hours of Le Mans and finished the race.

Cadillac Super Cruise users are about to get a $25 per month surprise: 3-year trial expiring

Always read the fine print. That’s the lesson Cadillac Super Cruise users are about to learn.

First reported by Motor Trend in September, Cadillac’s Super Cruise hands-free driver assist systema Level 2 system—comes with a three-year trial before requiring a subscription for continued use.

For the earliest adopters, that trial is about to end. Super Cruise was first offered on the 2018 Cadillac CT6 (it was standard on the Platinum trim and part of a $5,000 package on Premium Luxury models), with vehicles arriving in showrooms in September of 2017.

Cadillac spokesman Stefan Cross confirmed to Motor Authority the original trials are about to end and owners are being notified on 30 days before the three-year trial expires.

Cross told Motor Authority that 2018 CT6 Super Cruise owners will get an extra year on the initial three-year trial.

“Looking at the original disclosure and current disclosure, both say owners will need an active Super Cruise subscription and OnStar plan,” said Cross. And it was displayed on the window sticker under the Cadillac Owner Benefits section.

Super Cruise is more than the hardware embedded into the vehicle. “Super Cruise requires both OnStar and connectivity to operate,” Cross said. The mapping data and updates all require a connected service plan.

Cross said customers can purchase a stand alone Super Cruise plan for $25 per month or add Super Cruise to certain OnStar bundles for $15 per month.

“At this point customers will have the option to renew to keep Super Cruise working properly or let it lapse,” Cross notes, with different pricing options for customers, including a standalone subscription option. “It won’t be a one-size fits all.”

Super Cruise received a large update in 2019 that allowed it to work on 200,000 miles of highway in the U.S. and Canada. The update added 70,000 miles of map data to the CT6 sedans that featured Super Cruise.

When the system arrives on the 2021 CT4 and CT5, along with the 2021 Escalade, it will gain the ability to change lanes with the tap of a turn-signal stalk.

Update: This article has been updated with Super Cruise subscription pricing.
