A secret prototype that merges two icons to create an incredible sports car experiment.

Ferdinand Piëch’s legacy at Volkswagen Group was a mix of visionary projects and ambitious experiments. While best known for approving engineering marvels like the Bugatti Veyron, he also oversaw unconventional prototypes that few people ever saw. One such example is the TT Coupe RS4, a one-off that looks like a standard Audi TT but is, in reality, a hybrid of the TT and the first-generation RS4 Avant. The project took eight months and combined the RS4’s underpinnings with the 8N-generation TT body, creating a prototype that tested the boundaries of Audi’s sports car capabilities.

Engineering Magic Under the Hood

Despite its TT silhouette, almost everything beneath the body came from the B5 RS4: axles, engine, transmission, rear differential, and wheels. To fit the TT’s compact proportions, engineers shortened the chassis by 170 millimeters ahead of the fuel tank. Beneath the hood sat the RS4’s twin-turbo 2.7-liter V6 engine, longitudinally mounted–a first for any TT. Power reached all four wheels via a Torsen rear-biased differential and a six-speed manual gearbox, producing 375 hp and 440 Nm of torque, making this TT prototype more RS4 than TT in performance.

Performance That Surprised Everyone

The TT Coupe RS4 accelerated from 0 to 100 km/h in 4.9 seconds, with a top speed of 280 km/h, proving it could rival contemporaries like the Porsche 911. Although the platform swap increased the weight to 1,550 kg, the car remained incredibly agile. Stephan Reil, former head of quattro GmbH, described it as “unbelievably fun to drive”, even outperforming 911 models of the time. Nearly 20,000 km of testing validated its capabilities, showing that Audi engineers were pushing the TT platform to its limits.

Why It Never Reached Production

Despite its brilliance, the TT Coupe RS4 proved too expensive to produce at scale. Piëch’s vision for a TT-supercar hybrid ultimately paved the way for the Audi R8, developed alongside the Lamborghini Gallardo. While the TT and R8 have since been discontinued, this prototype remains a rare testament to Audi’s experimental spirit and technical daring, blending everyday usability with high-performance engineering.

The Future of Audi Sports Cars

Audi continues to explore the sports car segment, now with electric mobility in mind. A new production version of the Concept C, expected in 2027, promises to carry forward Piëch’s ethos–innovative, daring, and fast, but fully electric. The TT Coupe RS4 may have been a prototype, but its story highlights the bold experimentation that defined an era of automotive excellence and continues to inspire today’s engineers.

Volvo Safety Coach Helps Drivers Save on Insurance Rates

Published

on

Volvo has launched Safety Coach, an optional app that analyzes driving behavior, provides personalized safety tips, and could help eligible drivers lower insurance costs.

Volvo Cars is introducing Safety Coach, a new optional app designed to help drivers develop safer habits while potentially reducing their insurance costs.

The system provides driving feedback through the vehicle’s infotainment display and the Volvo Cars mobile app. It analyzes everyday driving behavior, including braking, acceleration, and cornering.

Each driver receives a personalized Safety Coach score that changes based on their driving habits.

Personalized feedback for safer driving

The app uses Volvo’s decades of real-world safety research to generate individual driving insights.

Volvo Safety Coach provides personalized driving feedback through the vehicle’s infotainment system.

Drivers can receive real-time tips designed to encourage smoother and more predictable driving.

Volvo says behaviors such as excessive speed and sudden maneuvers can make vehicles less predictable for other road users. By encouraging drivers to avoid abrupt actions, the system aims to reduce potential collision risks.

The company sees this type of feedback as another tool for improving everyday road safety.

Insurance rewards could follow safer habits

Safety Coach is not limited to driving advice. Volvo is also connecting the program with usage-based insurance opportunities.

The first rollout is taking place in Sweden and Norway. Customers in those markets will be able to opt in to share their driving data with affiliated insurance providers.

Drivers in Sweden and Norway can opt in to share driving data for potential usage-based insurance benefits.

Volvo says eligible customers can receive offers from Volvia based on their driving behavior.

The approach gives drivers the possibility of receiving personalized insurance benefits when they demonstrate safer habits.

The company plans to expand Safety Coach to the United States and additional European markets after its initial launch. Insurance-related programs are also expected to become part of that wider rollout.

AI and telematics power the system

Safety Coach was developed through a collaboration between Volvo Cars and Cambridge Mobile Telematics (CMT).

CMT provides the algorithm used to calculate each driver’s Safety Coach score. The company specializes in telematics and AI systems focused on safer mobility.

Cambridge Mobile Telematics provides the technology used to calculate each Safety Coach score.

CMT says data from its safe-driving programs shows that participants often reduce behaviors such as speeding and hard braking.

For Volvo, that suggests personalized feedback can help drivers build better habits over time rather than simply providing information after an incident.

Drivers control their data

Privacy and transparency are also central to the system.

Drivers must first opt in to Safety Coach before using the service. They can then separately decide whether to share their driving information with participating insurance companies.

That second choice is optional and is intended to allow customers to receive potential usage-based insurance benefits without automatically sharing their information.

The Volvo Safety Coach therefore combines driving feedback, personalized scoring, telematics, and potential insurance rewards in a single system. Volvo says the goal is to help drivers become safer while giving them more control over their driving data and potential insurance savings.

The expansion gives Ford and Lincoln owners a more convenient way to understand their vehicles without searching through pages of documentation.

Questions, images, and vehicle-specific answers

The Ford AI Assistant can be accessed directly through the Ford or Lincoln smartphone app. A blue oval and spark icon appears in the upper-right corner when the feature is available.

Users can type a question or upload an image. The assistant then provides an answer based on the specific vehicle.

Ford’s AI Assistant is available through the Ford and Lincoln companion app.

That means drivers can ask detailed questions about everyday use. For example, the assistant can explain the required engine oil, cargo capacity, or how specific features work.

It can also provide guidance on BlueCruise, Ford’s hands-free highway driving technology.

The assistant can read real-time vehicle data

The system goes beyond the information found in the owner’s manual. Ford’s AI Assistant can also connect to the vehicle’s real-time telemetry through the companion app.

That allows the system to provide information about current vehicle conditions.

The AI Assistant can provide real-time information such as tire pressure, fuel level, and oil life.

Drivers can ask about tire pressure, fuel level, and remaining oil life. Location data can also be used to answer practical questions.

For example, a driver can ask whether the vehicle has enough fuel to reach a specific destination.

The assistant can also provide step-by-step guidance for simple problems. That includes troubleshooting a power window or explaining warning lights shown on the instrument cluster.

Ford plans deeper integration in 2027

Ford is already working on the next stage of the technology.

Beginning in 2027, the Ford and Lincoln AI Assistant is expected to be embedded directly into the infotainment systems of select vehicles.

Ford plans to integrate its AI Assistant directly into the infotainment system of select vehicles starting in 2027.

Instead of relying on a smartphone display, the embedded assistant will become part of the vehicle’s digital experience.

Ford plans to combine the assistant with its own vehicle data and connected services. That could create a more personalized system capable of responding to both vehicle-specific questions and other in-car requests.

Ford AI Assistant and Google Gemini will work together

GM EVs Get Native NACS Charging Across the 2027 Lineup

Published

on

General Motors is moving all Cadillac, Chevrolet, and GMC electric vehicles to native NACS charging ports for the 2027 model year.

General Motors is preparing to standardize NACS charging across its electric vehicle lineup. While current EVs can already access compatible North American Charging Standard plugs with an adapter, GM expects every 2027 model to feature a native NACS port.

The transition will cover Cadillac, Chevrolet, and GMC, giving customers a simpler way to access fast-charging networks across the United States.

GM is moving to native NACS charging

GM says all of its electric vehicles currently sold can use compatible NACS chargers. However, some 2026 models still require an adapter because they use a CCS charging port from the factory.

That will change for the 2027 model year.

GM plans to equip all 2027 Cadillac, Chevrolet, and GMC EVs with native NACS charging ports.

The company announced that it expects all 2027 EVs to launch with a standard NACS port, removing the need for an adapter when using compatible NACS fast chargers.

The move should also make road trips easier as more public charging stations adopt the NACS connector.

Which GM EVs already have NACS?

Not every 2026 GM electric vehicle needs an adapter.

The Cadillac Optiq already features a native NACS port for 2026. The Chevrolet Bolt is also equipped with NACS, although GM lists it as a 2027 model-year vehicle for its return to the market.

The Cadillac Optiq and returning Chevrolet Bolt already feature native NACS charging.

The 2026 Optiq offers up to 317 miles of GM-estimated range, depending on configuration. The new Bolt combines its native NACS port with an EPA-estimated 262 miles of range.

Other 2026 GM EVs can still use NACS fast chargers, but they require the appropriate adapter.

These include the Cadillac Escalade IQ, Escalade IQL, Lyriq, Vistiq, Chevrolet Blazer EV, Equinox EV, Silverado EV, GMC Hummer EV Pickup, Hummer EV SUV, and Sierra EV.

2027 GM EV lineup will eliminate the adapter

GM’s 2027 lineup will make the transition much simpler.

The company expects the following models to feature native NACS charging:

  • Cadillac Escalade IQ
  • Cadillac Escalade IQL
  • Cadillac Lyriq
  • Cadillac Optiq
  • Cadillac Vistiq
  • Chevrolet Bolt
  • Chevrolet Blazer EV
  • Chevrolet Equinox EV
  • Chevrolet Silverado EV
  • GMC Hummer EV Pickup
  • GMC Hummer EV SUV
  • GMC Sierra EV

The 2027 GM EV lineup will feature native NACS ports across Cadillac, Chevrolet, and GMC.

Customers with native NACS vehicles can still use Level 1 and Level 2 charging with the appropriate J1772 cable. They can also access CCS fast chargers with a NACS-to-CCS adapter.

Energy Pass adds another layer of convenience

GM is also simplifying the charging experience through its Energy Pass system, which is built into the MyChevrolet, MyCadillac, and MyGMC apps.

The service combines registration and payment for multiple charging networks. Currently supported networks include Tesla Supercharger, IONNA, Electrify America, and ChargePoint, while EVgo is planned for future support.

The goal is to reduce the number of apps and passwords drivers need when charging on the road.

For GM, the move to GM EV NACS charging represents a major step toward a more consistent EV ownership experience. By 2027, customers should have native access to the NACS network across the entire Cadillac, Chevrolet, and GMC electric vehicle lineup.
