Volvo recalls 27,457 new vehicles over a brake-by-wire issue

Eight Volvos from the 2023 model year have been drawn into a recall over software in their brake-by-wire systems. The models at issue are everything Volvo sells — the C40, XC40, S60, XC60, V60, V60 Cross Country, V90 Cross Country, and XC90. The combined recall population numbers 27,457 cars. The problem is that an in-vehicle diagnostic test to check the grounding of the system can trigger a fault in the vehicle's Brake Control Module 2. The fault doesn't always occur, but when it does, the vehicle reverts to its hydraulic system so the car can still stop. However, without the brake-by-wire system, the driver doesn't get the benefit of software-defined safety systems like ABS, ESC, Traction Control as well as convenience features like Pilot Assist, adaptive cruise control and one-pedal driving. Drivers might be alerted to the situation with a warning message and malfunction lamp in the gauge cluster, or a stiff brake pedal. The automaker says it has had no reports of accidents, injuries or fatalities because of the problem. If the car is turned off and able to enter what Volvo calls "deep sleep," the electronics will clear the fault. To fix the issue, Volvo will send an over-the-air update with logic that's a better fit for the Brake Control Module 2 hardware. The automaker says the new code "will be implemented on February 20" of this year, but in another example of the digital world outpacing regulatory processes, Volvo will begin notifying owners on March 15.

Volvo Polestar reveals new V8 Supercars engine

Volvo may be better known for turbo fives and inline fours, but in 2005 it launched the XC90 with a new eight-cylinder engine built for it by Yamaha. Fast forward to this past June when Volvo announced its intention to enter Australia's V8 Supercars series, where it would compete with the likes of Ford, Holden, Nissan and Mercedes-AMG. This is the engine with which it intends to do so.
Revealed this weekend at the Sydney 500, this competition-spec powerplant is based on the same B8444S that powered the XC90 and S80 (not to mention the Noble M600), but tuned for racing duty to be shoehorned into the new S60 touring car. The 60-degree aluminum block has been bored out from 4.4 liters to 5.0, its compression ratio boosted to 10:1, modified to run on E85 bio-ethanol and its redline increased to 7500 rpm. Volvo also promises a unique engine note from its new racers.
While Volvo and its racing partner Polestar haven't released official output numbers, regulations call for outputs between 620 and 650 horsepower - in any event, a whole lot more than the 311 hp it produces in stock form. (Noble managed to squeeze that much out of the same block, but that required twin turbochargers while this unit remains naturally aspirated.) Scope out the details in the press release below and the photos from the reveal in the gallery above.

Volvo studying test of electric roads in Sweden

Volvo already announced the results of a study of wireless charging using a stationary C30, and now it's embarking on a more ambitious study of wireless charging involving moving city buses. Next year, in conjunction with the Swedish Transport Association, Volvo will build a section of electric road up to 500 meters long that would use inductive charging to refill the batteries while the bus drives over it.
Right now, the company's Hyper Bus diesel hybrid has to stop to plug in and charge at the end of its route. The company is looking for a way to keep buses in service while being able to run on electric power for greater lengths of time. The new line used for the study will be called ElectriCity, and will come online in central Gothenburg sometime in 2015. There's a press release below with more information.
