Mercedes-AMG to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.

Mercedes warms up the SLC

The Mercedes-Benz SLC moniker was once thought to be revived for the vehicle that became the Mercedes-AMG GT, but the German luxury brand is now rumored to use the name for its upcoming refresh for the SLK. Our spies recently snapped some shots of the updated hardtop convertible testing while not wearing much camouflage. These photos suggest not to expect any significant changes in styling for the refreshed SLK. The lower portion of the front bumper has a single center opening, and the grille gets the latest iteration of Mercedes' single-bar design. The camouflage offers more concealment at the rear, but there's clearly something to hide. The exhausts are better incorporated in the shape, as well. Mercedes is also expected to update the SLK's powertrains with the refresh into the SLC. There could be an AMG Sport version to slot between the regular model and full-bore AMG. Like the C450 AMG Sport, this one might use the brand's 3.0-liter, twin-turbo V6 with 362 horsepower. Related Video:

Car dealers, factories and ports close in the path of Hurricane Florence

Hurricane Florence has caused CarMax to close four stores in North Carolina, South Carolina and Virginia. The closed locations are in Myrtle Beach, Charleston, Winterville and Virginia Beach. It is possible for the company to close more stores, reports Automotive News. Daimler and Volvo have also shuttered their manufacturing facilities in the region to prepare for Florence. The storm is expected to reach North Carolina and South Carolina today or tomorrow. Automotive News says every coastal car dealer it reached on Tuesday was closing, and others not in the projected landfall area were monitoring the situation. There are approximately nine million vehicles in operation in the area that Florence is expected to hit, with a vehicle density of 162 vehicles per square mile. It is likely that not as many vehicles will be lost as during hurricanes Harvey and Irma, as population is less dense; areas affected by those storms had over 300 vehicles per square mile. The chief economist of Cox Automotive told Automotive News that some 20,000 to 40,000 vehicles could end up flooded if Florence keeps its path; however, recent reports have indicated Florence has weakened to a category 2 hurricane on Thursday. Tesla has again unlocked more range for some of its older models to make evacuation easier; the same was done a year ago in preparation for Hurricane Irma. As well as automotive manufacturers and dealers, automotive transport providers are readying for the storm and clearing cargo away. The container and auto terminals at Port Charleston will be closed from Thursday to Saturday, affecting part shipments to the BMW manufacturing facility in Spartanburg; BMW's spokespersons have said no production disruption is expected. Parts are delivered via railroad to Spartanburg by Norfolk Southern, which is also suspending operations for the time being. Vehicle hauler United Road has moved its rigs to safer regions and suspended deliveries, and car carrier vessels are trying to make it away from the storm's path in time.
