Trek Domane Gen 5 returns to basics, trimming 305 g by dropping IsoSpeed

Trek’s Domane Gen 5 trims about 305 g by dropping IsoSpeed and in-frame storage, relying on a revised carbon layup, a round seatpost, and 40 mm tyre clearance to preserve comfort. The lighter frame and fork enable six sizes and builds from 900 Series to 500 Series, with top models around 6.63 kg, a 20 mm rise cockpit for a more upright endurance ride, and no in-frame storage but extra bag mounts; 35 mm tyres are supported, balancing aero and rolling resistance. Pricing spans the range from entry SL to high-end SLR models as Trek positions it as a lighter, more affordable all-road carbon option.

IndyCar unlocks a faster, lighter era with the IR-28 for 2028

IndyCar has unveiled the IR-28, a ground-up redesign built with Dallara for a 2028 debut that promises faster lap times and enhanced safety. The car weighs about 100 pounds less than today’s chassis and uses a 2.4-liter twin-turbo V6 hybrid producing up to 760 hp, paired with a new AXIS inertance suspension and redesigned aerodynamics, including an integrated aeroscreen and cockpit upgrades. Chevrolet and Honda back the powerplant, with testing kicking off at tracks like Indianapolis Motor Speedway and Sebring as IndyCar pursues track records and closer wheel-to-wheel racing.

BMW's 2027 M3 CS Handschalter: A 75-Pound Manual Finale

BMW unveils the 2027 M3 CS Handschalter, the lightest M3 yet at roughly 3,765 lb thanks to CFRP, titanium exhaust, forged wheels and carbon bucket seats, with carbon-ceramic brakes as an option. It uses the entry-level rear-drive M3 and a 3.0L twin-turbo inline-six delivering 473 hp and 406 lb-ft, exclusively paired with a six-speed manual. Weight savings come from CFRP and the optional brakes, while suspension tweaks bring it closer to CSL handling; 0–60 mph is 4.1 seconds and a 180 mph top speed with the Driver’s Package. Priced from $108,450 (destination included), it’s a limited U.S. and Canada edition with July production and fall deliveries. Color options include Black Sapphire, Isle of Man Green, and two $4,500 retro hues: Techno Violet and Imola Red. The model is pitched as the final manual, rear-drive M3 chapter, ahead of rumored electrified and AWD successors later this decade.

"2025 Toyota 4Runner: Overhauled with Hybrid Powertrain and Roll-Down Rear Glass"

The new sixth-generation Toyota 4Runner almost didn't include the iconic roll-down rear window due to weight concerns, but it was ultimately deemed essential to preserve the vehicle's off-road heritage and customer expectations. Chief engineer Ketia Moritsu and the team prioritized weight reduction in other areas to accommodate the feature, recognizing the window as integral to the 4Runner's identity. The decision reflects Toyota's commitment to honoring the vehicle's 40-year heritage and understanding its customers' needs, such as accommodating surfboards and pets.

Long-Term Use of Tirzepatide Sustains Weight Reduction in Adults with Obesity

A phase 3 clinical trial evaluated the effect of tirzepatide, a once-weekly subcutaneous medication, on the maintenance of weight reduction in individuals with obesity or overweight. After 36 weeks of treatment, participants experienced a mean weight reduction of 20.9%. During the subsequent 52-week double-blind period, those who continued tirzepatide treatment maintained and further reduced their weight, while those who switched to placebo experienced a 14% weight regain. The study highlights the importance of continued treatment with tirzepatide in sustaining weight loss and preventing weight regain in individuals with obesity or overweight.

"Focus Izalco Max: Sacrificing Comfort for Speed and Performance"

Focus has released the new Izalco Max, claiming it to be their "fastest ever bike" due to redesigned tube shapes inspired by aeroplane wings.

However, the increased stiffness comes at the cost of comfort, with the new frame being 48% less comfortable. The Izalco Max is available in various builds, with prices ranging from £2,899 to £8,699.

iPhone 15 Pro: Lighter Feel, Titanium Colors, and Anticipating the iPhone 16 Ultra

The iPhone 15 Pro not only weighs less than its predecessor due to a switch from stainless steel to titanium, but also feels even lighter than its actual weight reduction suggests. This is because of a change in the device's moment of inertia, which measures an object's resistance to rotational motion. By reducing mass predominantly at the phone's outer edges, Apple has achieved a significant reduction in moment of inertia, making the iPhone 15 Pro feel more agile and nimble, amplifying the impression of lightness.

"Japan Airlines' Innovative Solution: Ditch Your Suitcase and Travel Light"

Japan Airlines has launched a year-long trial of a service called Any Wear, Anywhere, which allows travelers to book a set of clothes that will be waiting for them at their hotel upon arrival. The clothes are then returned, washed, and reused. The airline believes this service could reduce carbon emissions by cutting down on the weight carried by its airplanes. The trial will assess the impact on weight savings and emissions reduction, taking into account the deliveries and laundering of the clothes. The response to the service has been positive, with requests from over 115 countries. If successful, Japan Airlines hopes to expand the service to other airlines and alliances worldwide.
