IndyCar is considering whether to commission a new chassis from Dallara or continue updating the existing DW12 and IR18 models. The decision depends on future engine and energy recovery system (ERS) developments, with a potential shift to a high-voltage ERS possibly necessitating a new chassis design by 2027.
The Dallara DW12, a prominent chassis in IndyCar racing, is set to make its 200th race start at the season-opening event in St. Petersburg. Originally introduced in 2011, the DW12 has undergone significant transformations over the years, including safety improvements and aero kit changes. Despite initial criticisms, the chassis has become a mainstay in IndyCar, with drivers like Scott Dixon and Graham Rahal having contested all 200 races in the DW12. While the car's longevity is impressive, there are calls for a new chassis to be introduced in the near future.
IndyCar is considering the development of a new chassis for the sport, potentially ready by 2027, along with a new powertrain featuring a hybrid system. This move aims to attract additional OEMs by lowering cost barriers and making the sport more relevant to the auto industry. The potential 2027 debut would coincide with the expiration of current engine manufacturers' contracts, emphasizing the need for technological relevance and cost-effectiveness. The recent adoption of a hybrid system and its success will play a significant role in Honda's decision to continue in the sport. Teams are currently focused on containing costs, particularly with the introduction of the hybrid system, as they face significant expenses for component updates.
The Alpine A524 F1 car may look similar to its predecessor, but it has undergone significant re-engineering, including a new rear suspension system, optimized front suspension, and improved thermal management for brakes. The team aims to enhance competitiveness despite an expected power deficit in the Renault power unit. The chassis redesign has allowed for a new sidepod layout and rear suspension, with changes to improve airflow and consistency through corners.
Optimizing hybrid power is the current priority for IndyCar, with the focus on improving the quality of racing and attracting a third original equipment manufacturer (OEM). Despite calls for a new chassis, the trusted Dallara DW12 will continue to be used, undergoing significant updates to support the move to hybrid engines. The series hopes that the introduction of hybrid technology will entice additional auto manufacturers to join, and the success of the hybrid system will determine the possibility of a new chassis in the future.
The upcoming iPhone 15 Pro is expected to feature a titanium frame made of Grade 5 Titanium, offering improved durability and a lighter device. The titanium chassis will have a brushed finish, reducing scratch visibility and improving fingerprint resistance. The new color option, Titanium Gray, will replace the gold option. The iPhone 15 Pro and Pro Max are expected to be lighter than their predecessors by 18 grams.
Apple has been granted a patent for "Spatial Composites," which involves embedding metal or ceramic with a chassis for scratch resistance. The patent aims to make an iPhone chassis that looks and feels as smooth as current ones but can stand up to more wear and tear. The patent includes drawings showing different shapes of "abrasion-resistant members," each with different benefits but the same overall aim. The spacing between them is only between 10 and 100 microns.
Alex Rins, riding for LCR Honda Castrol, tested Marc Marquez's factory-spec Honda chassis in Argentina and found improvements in the bike's rear grip and traction. Rins also expressed interest in testing the chassis that Joan Mir is currently using. LCR Honda is hoping to give HRC as much information as possible to improve the bike's setup.
