AMG-powered Aston Martins still years away

After flirting for several years, Mercedes-Benz and Aston Martin have finally tied the knot. Just don't expect to see any offspring to result from the union for at least three or four years.
This according to Auto Express, which spoke with Daimler chief Dr. Dieter Zetsche at the Frankfurt Motor Show last week. AE reports that a new range of AMG-developed turbocharged V8s, transmissions and electrical components will make their way into the successors to the current V8 Vantage and DB9, but that these models are still a few years off.
Purists might balk at the thought of a Mercedes-powered Aston holding true to the brand's heritage. But while David Brown (for whom the DB range is named) may have steered clear of shoehorning in Detroit muscle into his cars, the entirety of the company's current range is powered by engines borrowing technology from Ford, and that arrangement seems to have worked well for Aston until now. And if you're still skeptical, look no further than Pagani and its AMG-sourced engines and you should have all the proof you need that the new relationship between Daimler and Aston could be a success.

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:

2016 Mercedes-Benz G550 Quick Spin [w/video]

If there ever was an automotive embodiment of the phrase, "If it ain't broke, don't fix it," that'd be the Mercedes-Benz G-Class. The G-Wagen has carried on largely unchanged since the 1970s, with only small updates throughout the decades. Today, it's the halo vehicle for Mercedes' entire SUV range, and while it's more luxurious and efficient than ever, it'll still climb a mountain if asked. "Our legend has a bright future," says Dr. Gunnar Guthenke, Mercedes' G-Class boss. And for now, that means the addition of a new base engine for the 2016 model year, as well as other small updates. The powerplant in question is Merc's new twin-turbocharged, 4.0-liter V8 – you know, the one from the AMG GT – tuned to produce 416 horsepower and 450 pound-feet of torque in the G550. Compared to the outgoing, naturally aspirated, 5.5-liter V8, the new engine is stronger by 34 hp and 59 lb-ft. And while official fuel economy numbers are still pending, Mercedes says the G550 is 17-percent more fuel efficient with this smaller, more powerful engine. Win-win. As for the rest of the G-Class, the 2016 model year changes are limited to a new front bumper with more pronounced air intakes (and the removal of the cow catcher bars), wider wheel arches, a few new colors (including some seriously bright hues), and a redesigned instrument cluster. Those are all well and good, but the star of the show is that 4.0-liter V8. It's a honey in the AMG GT, and it's a perfect fit under the hood of the G550. Driving Notes I'm kicking myself for not taking video of the exhaust note, because holy crap, the G550 sounds amazing. Mercedes' engineers should be applauded for the exhaust tuning on the updated G-Class. The result is a low, burbly, throaty V8 noise that comes bellowing out the SUV's side pipes. The extra 59 lb-ft of torque is really noticeable off the line. And like in the AMG GT and C63, the 4.0-liter V8 provides linear power delivery with no noticeable turbo lag. Mercedes says the 2016 G550 will do 0-60 in 5.7 seconds, compared to 6.0 seconds in the 2015 model. That's right, it's a 5,724-pound, box-shaped SUV that'll run nearly neck and neck with a base Porsche Boxster. In terms of on-road refinement, the G-Class is the same as it ever was. There's an optional, adjustable suspension for 2016, with Comfort and Sport modes, but the difference between the two settings is negligible.
