Twin-turbo Cadillac CTS coming

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Tesla says Model 3 is best-selling midsize premium sedan in America

Auto sales figures are sort of fuzzy numbers, no matter how you slice them and no matter which manufacturer you're talking about. Unless you're specifically tracking vehicle registrations, automakers generally self-report the figures. So, you have to trust that they aren't doing anything too tricky. Plus, not every sale is equal, as some are logged as dealership loaners or demo models, some go to fleets (like to a rental car agency), and still others are, of course, bought by traditional customers looking for a new daily driver. With that preamble out of the way, when we saw a tweet from Tesla claiming that the all-electric Model 3 is the best-selling midsize premium sedan in America, our interest was piqued. According to Tesla, market share of the Model 3 has just surpassed the Mercedes-Benz C-Class, which had up until now led the Audi A4, BMW 3 Series, and Lexus IS as the best-selling sedan in its class. Note that the graph from Tesla below is, we think, specific to four-door models. So, is it true? Judging by the numbers we can find, including some from Bloomberg, which has a running chart to track Model 3 registrations, the answer is... probably. We don't know exactly how many Model 3 sedans Tesla is currently cranking out, but Bloomberg estimates production at about 2,560 units per week, and total sales for 2018 at 34,414. We know the number is increasing regularly, though, and Elon Musk has said most recently production sits around 500 units per day, which, on a seven-day cycle, would be 3,500 per week. We looked up Mercedes' sales figures for the month of May, 2018, and found that the German brand sold 5,419 C-Class models last month, for a total of 23,917 for the year (incidentally, that's down more than 30 percent from the year prior). While the bulk of those sales would surely be made up of sedans, it would also include a small percentage of coupes. Either way, it's likely that Tesla is currently producing and selling more Model 3s than Mercedes is C-Classes. Now, it's also worth considering if the C-Class is the only vehicle from Mercedes that directly competes with the Model 3. We'd guess customers may also cross-shop the CLA sedan with the Tesla, and if that's the case, you might decide it's worth adding in Mercedes' 2,527 CLA-Class sales last month and 9,622 so far for the year. The same argument could be made for certain versions of the BMW 2 and 4 Series.
