Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

The 10 car brands most expensive to maintain over 10 years

Car maintenance has got to be one of the least fun things you can do with your free time, right behind going to the dentist and filing your taxes. However, depending on the brand you buy, your time spent at the shop could be much more than you bargained for. Consumer Reports’ new study on the most- and least-expensive-to-maintain car brands found that European car companies are most likely to break your wallet with costs nearly five times that of the automakers at the other end of the spectrum. Land Rover had the highest ten-year maintenance costs, at an average of $19,250. Porsche was second worst with $14,090 in costs. 10 car brands most expensive to maintain over 10 years: Land Rover: $19,250 Porsche: $14,090 Mercedes-Benz: $10,525 Audi: $9,890 BMW: $9,500 Volvo: $9,285 Infiniti: $8,500 Acura: $7,800 Mini: $7,625 Subaru: $7,200 The Euro brands at the “top” of this list arenÂ’t all that surprising. Land Rover has consistently landed as one of the most expensive vehicle brands to maintain for years now, though Porsche is generally viewed as being one of the more solid performance brands. That could suggest that some models donÂ’t always require more repairs, but the fixes they do need are significantly more expensive. Tesla, Buick, and Toyota were the three cheapest to maintain car brands, with 10-year maintenance costs of $4,035, $4,900, and $4,900, respectively. Consumer Reports noted that these numbers could be slightly skewed due to the fact that some automakers offer free maintenance for the first few years of ownership, and all companies cover their new vehicles for at least a few years after the purchase. Routine maintenance is a great way to avoid costly repairs over time, as itÂ’s much cheaper to catch a problem before it starts causing other issues. Check your oil, rotate your tires, and avoid driving like a wild person, and youÂ’ll likely fare much better than others, even if you own one of the scarier-to-maintain brands.
