Lazareth LM847 packs a Maserati V8 into a leaning quad frame

You want to know what insanity looks like? This is it. It's called the Lazareth LM847, and to boil it down to its essence, it's basically a sport bike built around a Maserati V8. Now this isn't the first motorcycle we've seen packing a giant car engine. There've been more custom jobs than we could list here, and of course there's the Boss Hoss – an American cruiser with a 5.7-liter Chevy V8 at its heart. And we'd be loathe to leave out the V10-powered Tomahawk concept from this discussion. But this is another matter entirely. The LM847 is made by a French outfit called Lazareth. It's the same company responsible for the Wazuma quad bike, the Wazuma GT roadster, and that bonkers Renault Twingo with the Range Rover V8 in the back. In other words, Lazareth knows crazy, and hasn't skimped on it this time. For its latest project, Lazareth started with a 4.7-liter V8 – the kind you used to find the Quattroporte or Alfa Romeo 8C Competizione before Maserati started downsizing and bolting on turbos. It produces 470 horsepower and 457 pound-feet of torque, channeled through a single-speed hydraulic coupling in place of a multi-gear transmission. Strictly speaking, it's not a motorcycle, but a quad – owing to the tandem wheels at each end. But it has a saddle and handlebars, and looks like it would lean in a fair bit in the turns. We're not about to find out though, because we don't have a death wish. Related Video:

Stellantis announces ‘Circular Economy’ business to drive revenue, decarbonization

Stellantis has already announced its plans to reach net-zero carbon emissions by 2038. Today, the automaker has announced a new business unit to help it reach that goal while generating 2 billion euros per year in revenue by 2030. The “Circular Economy” business will help make revenue less dependent on finite, rare and ecologically problematic materials. The Circular Economy model features what Stellantis calls a “4R” strategy, comprising remanufacturing, repair, reuse and recycling. The goal is to make materials last as long as they can, reducing reliance on the acquisition of those precious new materials in the future by returning them to the business loop when theyÂ’ve reached the end of their first life. Through these processes, Stellantis says it can save up to 80% raw material and 50% energy compared to manufacturing a new part. Remanufacturing, or “reman” in Stellantis shorthand, means dismantling, cleaning and rebuilding parts to OEM spec. Nearly 12,000 remanufactured parts are available for customers to purchase. Some remanufacturing is done in-house, and some with partners and through joint ventures. Repair is pretty obvious — fixing parts to put back into vehicles. This also consists of reconditioning, to make a vehicle feel like new. Stellantis boasts 21 “e-repair” centers for repairing electric vehicle batteries.  Reuse refers to parts still in good condition from end-of-life vehicles sold as-is. Stellantis says it has 4.5 million multi-brand parts in inventory. These are sold in 155 countries through the B-Parts e-commerce platform. Reuse also refers second-life options, such as using batteries outside of automotive purposes. Recycling involves dismantling parts and scraps back into raw material form that is then looped back into the manufacturing process. Stellantis says it has collected 1 million parts for recycling in the past six months. Recycling doesnÂ’t get counted in that aforementioned 2 billion euros of revenue, but it does save the company money on acquisition of raw materials. As for batteries, specifically, Stellantis expects this recycling business to ramp up after 2030, when the packs currently in service begin to reach the end of their lifecycle. Stellantis will use its new “SUSTAINera” label to denote parts that are offered as part of its Circular Economy business.

Alfa Romeo Giulia to get Ferrari-related engine

Alfa Romeo has a long, proud history of using V6 engines in its coupes, sedans, and sports cars over the years, but as the new Giulia sedan approaches, the Italian marque is allegedly turning to Ferrari for its next six-cylinder. This is obviously not the first time a Ferrari-sourced or derived engine has been found under an Alfa's long hood. While 8C Competizione famously used a version of Ferrari's F136 V8 during its short run, the Giulia's new V6 will be offered on a much larger scale, slotting in above an entry level, four-cylinder turbo (likely the next-gen version of the 4C sports car's 1.75-liter engine). According to Autocar, the new V6 will be "specially developed for Alfa Romeo," and will be built at the Termoli engine factory alongside the new turbo four-cylinder. As for the rest of the Giulia, Autocar has been able to shine a light on a number of other details about the new midsizer. It will, thankfully, be rear-wheel drive, and designed to counter the "mostly cold and clinical" and soulless cars of the German competition, Maserati chief Harald Wester told AC. Some of the new sedan's structural elements will even be shared with Maserati's entry level model, the Ghibli. Most notable of all, though, is what the Giulia means for American consumers. After the limited-run 8C and the niche 4C, the new sedan will lead Alfa Romeo's long-awaited, large-scale return, where it will combat the popular BMW 3 Series, Mercedes-Benz C-Class, Audi A4, not to mention rivals like the Cadillac ATS and Lexus IS. Look for more on the Giulia next week when it's officially revealed in Milan.
