Gordon Murray Automotive is making the world's lightest, most driver-focused supercar

A new car from Gordon Murray Automotive (GMA) promises to be the lightest, most driver-focused supercar in the world. The formula GMA is using eschews the current trend of increasing power and quickness.

Traditionally, automakers focus on getting the power-to-weight ratio in a vehicle just right for their audience. A lightweight car doesn't need a lot of horsepower to get where it's going in a jiffy. Heavy vehicles need a substantial amount of power just to get going.

GMA's T.50 model will have 100 horsepower to propel every 150 kg of car. The total weight of the vehicle is just 980 kg (2001.8 pounds). The company is installing a 650-horsepower V12 engine in the T.50.

GMA says that the typical supercar (1,236 kg) has 100 horsepower for every 210 kg of car - a 40 percent increase over the T.50. In order to match the power-to-weight ratio of the T.50, the traditional supercar would need an additional 300 horsepower in addition to more substantive equipment.

Engineers have cut the weight of the car's V12 to just 180 kg. That makes it more than 60 kg lighter than the BMW S70/2 V12 in the McLaren F1 – while generating more power.

The car's lightweighting isn't due to its stripped back race track-focused interior. In fact, GMA will offer the car with more comfortable, practical, and drivable styling and engineering than is typical in modern lightweight supercars. Professor Murray said: "Designing a lightweight sports car does not come from specifying exotic materials alone, it comes from a state of mind, from absolute focus and control, and from a deep understanding of lightweight, optimized design."

Proportionally, the T.50 is smaller than a Porsche 911. GMA says that it offers space for three and luggage inside. The centrally positioned racing-style driver's seat weighs less than 7 kg. The two passenger seats, both of which sit behind the driver, are less than 3 kg each.

It's made of a carbon fiber monocoque and body panels that weight less than 150 kg total.

To achieve GMA's lightweighting goals for the T.50, the company took a page out of the Jean Nidetch playbook and held weekly sessions to monitor the weight of the vehicle, down to the nuts, bolts, screws, and washers.

The company also used precise measuring technology to determine the exact size that these parts needed to be. According to GMA, "On many cars, these fixings are generic and far larger than they need to be. For the T.50, the diameter and length of each fixing (around 900 in total) was optimized by calculating the forces to which each would be exposed."

This meant even the smallest detail wasn't overlooked. The T.50's pedal box is 300 g lighter than the McLaren F1's and the glazing on nit is 28 percent thinner than usual. Still, the components still retain their structural integrity.

Dodge offers upgrades that push power to 885 ponies in some models.

Dodge

The world may be going electric, but Dodge is still offering plenty of support to owners of its famed Hellcat muscle cars. Today, the automaker announced a program to provide factory-backed performance parts for SRT Hellcat cars. The components can be ordered and installed by one of Dodge's "Power Broker" dealerships.

Called Direct Connection, the service is Dodge's official source for performance parts and other components. Dodge offers two kits for Challenger SRT models: Challenger SRT Hellcat Redeye cars can be upgraded to 885 horsepower and the standard Hellcat can be pushed to 750 ponies. In all, Direct Connection offers 14 kits for the Challenger and 13 race-ready kits. There are also four graphics packages for the Challenger Mopar Drag Park model.

Because of their connections with the company that designed and built the cars in the first place, factory-backed tuning and performance operations are usually top-notch. Dodge's program offers live technical support and an online catalog that allows users to mix and match performance parts using the site's "recipes." All parts that are installed or replaced by a certified Dodge dealer do not interfere with the cars' three-year/36,000-mile basic warranty or the five-year/60,000-mile powertrain warranty.

If Dodge-approved performance parts get you excited, you don't have long left to wait. The kits will go on sale late in the first quarter of 2022. The Dodge Power Brokers dealer network will also start around that time.

NHTSA looking into Tesla's in-car video games

Some owners have discovered that their car's video games work when the car is moving.

Tesla's vehicles are among the most advanced and forward-thinking products of any kind, but serious innovation doesn't come with tradeoffs. The automaker has been in the news recently because of issues with how its advanced cruise control systems function, and now, Autoblog reports that the NHTSA is asking questions about Tesla giving drivers the ability to play video games and browse the internet while driving.

The feature is intended to be used while the car is parked, such as while charging, so the discovery that people can use them while driving is a serious one. Vince Patton, the person who filed the complaint with the NHTSA, tested his car and found that he could play Solitaire and a fairly involved action game while it was in motion. Internet browsing was also possible, meaning the driver could take their attention completely off the road ahead for extended periods of time.

Tesla was already under investigation over crashes involving its Autopilot feature. Several collisions have occurred between Teslas and emergency vehicles stopped on the side of the road. Following the initiation of that investigation, the NHTSA raised other questions with the automaker over a buggy software update that was pushed out, retracted, fixed, and reissued outside of the normal recall process. Despite their names, it's important to clarify that neither the Autopilot nor Full Self-Driving features are capable of driving the cars without driver awareness and input.
