Ferrari patents a fancy and fascinating electric turbocharger

While turbocharging has improved vastly over the years, and it has enabled cars to become both more powerful and more efficient, there's always room for improvement. Turbochargers scavenge exhaust gas pressure and use it to turn a compressor that forces intake air into the cylinders. However, as the patent points out, this means the intake compressor and the exhaust turbine are physically coupled, and have to spin at the same rate. Ferrari's design divorces the two, and it's a happy breakup. The key is hooking up the two components of the turbo to their own individual electric motors, with an energy storage device in between. It's different than the electric supercharger systems you have seen on certain Audi products, for example. Those systems recover energy like a hybrid, store it, and then use it to drive an intake compressor. It supplements conventional turbochargers that harvest energy from the exhaust. In systems like Audi's, the electric supercharger is supplementing the sequential conventional turbochargers when they're not operating efficiently, at very low RPM in particular. It works well, but it's complicated, and it is a workaround for the limitations of a conventional turbocharger. See below for an animation of the Audi system. This content is hosted by a third party.

A smaller compressor generates boost more quickly, but loses efficiency at higher RPM. But there's way more energy in high-RPM exhaust gasses. By hooking up the turbine to an electric motor instead, you can harvest energy from the exhaust throughout the rev range, and particularly when the engine is pushing lots of gasses through. And you can store that energy in a battery if it's not needed at that moment. The intake-side compressor also has a reversible electric motor attached. It is not physically connected to the turbine, so it can operate at any time the computers decide it's beneficial. As engine RPM increases, the compressor doesn't have to increase its speed beyond its optimal range, so there's less energy wasted. And at low RPM situations, when a conventional turbocharger wouldn't have enough exhaust gas passing through its turbine side to generate useful boost in the compressor side, the electric motor can spin up Ferrari's divorced compressor to provide some boost.

Stellantis reports $15B profit in first year of merger

FRANKFURT, Germany — Automaker Stellantis said Wednesday that it made 13.4 billion euros ($15.2 billion) in its first year after it was formed from the merger of Fiat Chrysler Automobiles and PSA Group. The earnings nearly tripled profits compared with its pre-merger existence as two separate companies, as the maker of Jeep, Opel and Peugeot vehicles exploited cost efficiencies from combining the businesses. The result compared to a combined 4.79 billion euros for the separate companies in 2020 before the merger, which took effect on Jan. 17, 2021. Revenue for the combined business rose 14%, to 152 billion euros. CEO Carlos Tavares said the results “prove that Stellantis is well positioned to deliver strong performance" and had overcome “intense headwinds” during the year. Automakers have struggled with shortages of key parts such as semiconductor electronic components and rising costs for raw materials as the global rebound from the worst of the coronavirus pandemic brings more demand. The company said the benefits of the merger were worth some 3.2 billion euros during the year. Mergers can lead to streamlined costs as companies combine functions and spread fixed costs over a larger revenue base. The company accelerated its rollout of battery-powered vehicles, with sales of low-emission vehicles reaching 388,000 — an increase of 160%. Stricter environmental regulations in Europe and China are pushing automakers to roll out more electric vehicles with longer range. Stellantis started production of a hydrogen fuel cell commercial van under its Opel brand in December. Stellantis' other brands include Chrysler, Citroen, DS, Fiat, Maserati, Ram and Vauxhall.

Ferrari SF-15T will look to reclaim former F1 glories in 2015

The parade of cars for the 2015 Formula One World Championship continues apace, as Scuderia Ferrari has unveiled the vehicle that fans of the Italian team will doubtlessly be hoping drivers Sebastian Vettel and Kimi Raikkonen will pilot to victory. After the questionable styling of last year's vehicles, this new Ferrari continues the trend of more aesthetically pleasing designs. The vacuum-cleaner-like snout of last year's F-14T has been replaced with a longer, rounded bill that feeds more gracefully towards the cockpit. The new front end is arguably the most noticeable change for 2015, while changes elsewhere on the open-wheeler's body are mere evolutions of last year's design. In fact, that's kind of the theme around the SF-15T. The brake-by-wire system, clutch and gear ratios (which are locked after the first race) have all been optimized based on last season's experiences, while the weight of the car has increased by just 11 kilograms, as per sporting regulations. Take a look at Ferrari's batch of images showing its new challenger, and let us know whether you think this new design will fare better than last year's troubled F-14T. TECHNICAL FEATURE OF THE SF-15T The SF15-T the sixty first car built by Ferrari specifically to take part in the Formula 1 World Championship. It is the second car made by Ferrari since the reintroduction of turbo engines in 2014. The first year of these new regulations was extremely challenging for the Scuderia and the lessons learned have been applied vigorously to the SF15-T to create a car that is in every respect a large step forwards with respect to the F14-T. Chassis The most striking visual difference between the SF15-T and its predecessor is the lowering of the front end of the car in accordance with the change of regulations for the 2015 season. After a few seasons of rather unappealing aesthetics, the 2015 rules permit the SF15-T an attractive nose shape which also brings excellent aerodynamic performance. Aside from the nose area, the regulations for 2015 are largely unchanged. This has given the Team a stable base on which to engineer a much stronger chassis than the year before: A casual glance at the back of the car reveals a much more tightly packaged rear end which allows more downforce to be extracted from the critical surfaces around the rear of the car. The rear wing family has been extensively redesigned to deliver stable performance in corners while producing a larger DRS effect on the straights.
