Volvo XC90 Coasting Transmission Deep Dive | How, when and why of coasting

In our recent 2021 Volvo XC90 Recharge review, its turbocharged-supercharged-hybridized powertrain delivered impressive horsepower and fuel economy. But Volvo has one additional trick up its sleeve, propelling a car with power that's simpler, cheaper and all-natural: It's the power of momentum and gravity. I've always been halfway to a hypermiler. I'm not obsessive about it, but in city driving, I enjoy timing stoplight approaches to keep the wheels rolling and avoid the inertia of restarting from a stop. There's little point to needlessly racing and braking between red lights, wasting kinetic energy (and therefore fuel). So I tend to drive strategically instead, often catching up with the drivers who jackrabbit but get hung up at the lights. And, back when I owned a long line of vehicles with manual transmissions, I coasted. Coasting used to be slightly controversial. Some claimed it doesn't actually save gas, though my mileage calculations showed otherwise. Another school of thought insisted that removing engine braking from the equation, even momentarily, constitutes a dangerous loss of control. Of course, an experienced driver can slip a manual transmission back into gear in a flash when engine braking's actually needed. And one should always use some common sense and judgment about when and where to coast. I'm not talking about careening down a 15% grade into a school zone.  Anyway, those arguments became moot when automatic transmissions pretty much took over. (And no, never coast with a typical automatic transmission. Even if it weren't damaging to your type of automatic — but assume that it is — the risk of screwing up a nudge of the shifter from drive into neutral is too great.)

Volvo calls the feature on its Aisin eight-speed "Eco Coast." Some Mercedes, BMWs and others call it "sailing" or "gliding." The Hyundai Ioniq, Ford Mustang Mach-E and Polestar 2 are among EVs that allow you to cancel out all regeneration and freewheel downhill. And future cars such as the BMW iX are also being designed to do it. By building coasting into the clockworks, automakers have taken any traffic safety concerns out of the question, because the car will instantly switch you back into gear when needed.

Volvo EX30 due out in June 2023 as entry-level electric crossover

Volvo will expand its range towards the bottom when it presents an entry-level electric crossover called EX30 in June 2023. The company isn't ready to show us the soft-roader's full design yet, but it released a preview video that gives us a better idea of what to expect from it. "Something small is coming," Volvo wrote in a statement. While that's not a lot to go on, it suggests — but doesn't confirm — that the EX30 will slot below the XC40 in terms of size. We've seen it parked next to the EX90 and it looks considerably smaller; it rides on a much shorter wheelbase and features a relatively small rear overhang that creates a boxy silhouette characterized by an almost upright rear end. Many of the styling cues that define Volvo's current design language seem to appear on the EX30. Its front end wears T-shaped LED daytime running lights (called Thor's Hammer in the company jargon) inspired the EX90's, while its rear end features a new interpretation of the upright lights that Volvo has fitted to many of its cars over the past few decades — including the C30, which was its last 30-branded car. Technical details haven't been announced. All we know is that the EX30 will be all electric, all the time; it won't be available with a gasoline-powered engine. An unverified report claims that the city-friendly model will share its Sustainable Experience Architecture (SEA) platform with the Smart #1, among other models, and Volvo boss Jim Rowan said the crossover will deliver a "decent range." Using the SEA platform will allow Volvo to offer rear- and all-wheel drive as well as several battery options, though the lineup will vary from market to market. The Volvo EX30 will make its debut on June 7, 2023, at 1:30 p.m. European time, which is 7:30 a.m. in New York and — sorry, West Coast folks — 4:30 a.m. in California. We'll learn more about it in the coming weeks, and sales will start on the day of the unveiling. If the report is accurate, the EX30 will be built in China. Volvo confirmed to Autoblog that the model will be sold in the United States. Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

Volvo promises new direct-injected diesels, 8-speed auto

As a part of eliminating its dependence on Ford platforms and powertrains, Volvo has previously announced information about its Volvo Engine Architecture (VEA) and Scalable Platform Architecture (SPA), but now we're finally getting some details about what will power some of the Swedish automaker's next-generation products.
The biggest key to VEA on the diesel engines is a new technology Volvo calls i-ART. This system uses unique injectors at each cylinder capable of monitoring fuel pressure and adjusting accordingly to maximize fuel economy and performance and reduce emissions. Looking ahead, Volvo says its four-cylinder engines will be able to offer the power of a six-cylinder and eventually, mixed with some sort of electrification, will be able to rival the performance of a V8 and "turn V8s into dinosaurs."
More details about the new diesel injection technology is posted in the press release below.
