2.7 Diesel on 2040-cars

Cold start comparison: 2020 Alfa Romeo Giulia Quadrifoglio vs. 2013 Dodge Challenger SRT8

The 2020 Alfa Romeo Giulia Quadrifoglio is a five-seat, compact luxury sport sedan packing 505 horsepower thanks to a 2.9-liter twin-turbocharged V6. My personal 2013 Dodge Challenger SRT8 392 is ... well ... not. It's a full-sized muscle coupe whose iron-block 6.4-liter V8 makes 470 hp in the very traditional way: it's freakin' huge, like everything else about the car.  On paper, these two have nothing in common beyond the fact that they were built by the same multi-national manufacturing entity.  But if paper were the be-all and end-all of automotive rankings, everybody would buy the same car. And we don't, especially as enthusiasts. Whether it's looks or tuning or vague "intangibles" or something as simple as the way a car sounds, we often put a priority on the things that trigger our emotions rather than setting out to simply buy whatever the "best" car is at that particular moment.  So, what do these two have in common? They both sound really, really good. Like looks, sounds are subjective. While a rubric most assuredly exists in the world of marketing (attraction is as much a science as any other human response), we have no way of objectively scoring the beauty of either of these cars, and the same applies to the qualities of the sound waves being emitted through their tail pipes.  But we can measure how loud they are. In fact, there's even an app for that. Dozens, as it turns out. So, I picked one at random that recorded peak loudness levels, and set off to conduct an entirely pointless and only vaguely scientific experiment with the two cars that happened to be in my garage at the same time.  For the test, I opened up a window and cracked the garage door (so as not to inflict carbon monoxide poisoning upon myself in the name of discovery), and then placed my phone on a tripod behind the center of each car's trunk lid. I fired each one up and let the app do the rest. I then placed my GoPro on top of the trunk for each test so that I could review the video afterward for any anomalies.  I started with the Challenger. The 6.4-liter Hemi under the hood of this big coupe is essentially the same lump found under the hood of quite a few Ram pickups, and it has the accessories to prove it. Its starter is loud and distinctive. Almost as loud, it turns out, as the exhaust itself. As its loud pew-pew faded behind the V8's barking cold start, we recorded a peak of 83.7 decibels. In the app's judgment, that's roughly the equivalent of a busy street.

Chrysler Recalls Over 566,000 Trucks, SUVs

Fiat Chrysler is recalling more than 566,000 trucks and SUVs in two recalls for malfunctioning fuel heaters that can cause fires and a software glitch can disable the electronic stability control. The recalls bring the newly merged company's total for the year to 6.4 million vehicles worldwide and 5.1 million in the U.S. as it continues to struggle with reliability problems. It was not immediately clear whether those totals were annual records. On Tuesday, its longtime quality chief abruptly left after Fiat Chrysler performed poorly in Consumer Reports magazine's annual reliability rankings. The largest of two recalls announced Wednesday covers almost 382,000 Ram 2500 and 3500 pickups and Ram 4500 and 5500 chassis cabs from 2010 through 2014. In trucks with 6.7-Liter Cummins diesel engines, corrosion on a fuel heater terminal could cause overheating, fuel leaks and fires. Chrysler is not aware of any fires or injuries. Owners could be warned by an odor of diesel fuel. Customers will be notified by letters starting in December. Dealers will install upgraded terminals and fuel heater housings could be replaced. The second recall covers more than 184,000 Jeep Grand Cherokee and Dodge Durango SUVs from 2014. A debris cover over a circuit board in the steering column control module can disrupt communications and disable the stability control. The problem was discovered when dealers started getting reports from customers that electronic stability control warning lights were coming on. Fiat Chrysler says it knows of no crashes or injuries caused by the problem. Technicians will upgrade software to fix the SUVs, and customers will be notified in December. Fiat Chrysler has issued 33 global recalls and 27 in the U.S. so far this year. Doug Betts, its longtime quality chief, left the company to pursue other options after Consumer Reports' survey-based rankings this year showed four FiatChrysler brands at the bottom of its list. Dodge, Ram, Jeep and Fiat performed worst of 28 brands ranked by the magazine. Company spokesman Eric Mayne said Fiat Chrysler's recalls average fewer than 200,000 vehicles each, below the industry average of 301,000. That means the company is responding quickly to problems, he said, adding that eight of its 27 U.S. recalls were announced before the company received any consumer complaints. Chrysler is not alone with a high number of recalls so far this year.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
