MotorWeek fondly remembers the 2000 BMW M5

The Retro Review series from MotorWeek tends to reminisce about vehicles at are at least 20 years old and often from even further back. However, the show's latest recollection shines the spotlight on a fondly remembered sports sedan that's also a modern classic: the 2000 BMW M5. Years before BMW committed to downsized engines with turbocharging and shortly prior to the introduction of iDrive, the E39 M5 showed the Bavarian brand's engineering talents at their very best. By modern standards, the sedan's powertrain is almost antiquated. Up front, there's a big, naturally aspirated V8 that sends power to the rear wheels, and the only choice of transmission is a six-speed manual. But as MotorWeek explains, the tuning of the whole vehicle comes out to near perfection. This is a model that's definitely worth remembering.

2019 BMW M850i xDrive: How it compares on paper with other GT coupes

Although the hot new vehicles for the rich seem to mainly comprise SUVs and supercars, the neglected luxury GT coupe segment is starting to see some life again. The latest to add a spark to this set is the 2019 BMW M850i xDrive. It goes on sale later this year, and revives the 8 Series that's been dead since the 1990s. The first version available to Americans will be one with a twin-turbo 4.4-liter V8, with other versions likely following. Before it launches, we wanted to get a lay of the grand-touring land and see how the new BMW stacks up to the competition in performance, practicality and price. While some of these models have higher-performance or more-affordable iterations, we picked the versions that would be the closest match to this 8 Series model. They include the 2019 Lexus LC 500, 2018 Mercedes-Benz SL 550, 2018 Mercedes-Benz S 560 Coupe and the 2018 Maserati GranTurismo. We will also provide some short summaries on our experiences with these cars, but to get a full picture of each model, be sure to check out their full reviews. And if you want to compare any of these cars with models you don't see here, be sure to try out our car comparison tool. Engines, transmissions and performance On paper, the BMW M850i xDrive is clearly the performer of the group. It has the most power and torque at 523 horsepower and 553 pound-feet. Coupled with all-wheel-drive and an eight-speed automatic, the car is able to overcome its relatively portly 4,478-pound curb weight to hit 60 mph in a scant 3.6 seconds. That's more than half a second quicker than the lightest car in the group, the Mercedes-Benz SL550, which weighs 4,012 pounds. The other three vehicles are in the low- to mid-4-second range to 60 mph. Though the Maserati is the slowest to 60 mph, it does boast the highest top speed of 186 mph. The M850i and SL 550 are electronically limited to 155 mph, while the Lexus is limited to 168 mph. The Mercedes S 560 has the lowest top speed at an electronically limited 130 mph. View 52 Photos Of interest is that there's a 50/50 split among these cars between using a pair of turbos, and having none at all. The BMW and Mercedes resort to forced induction, whereas the Lexus and Maserati choose to stay naturally aspirated. This is likely why the Germans break 500 pound-feet of torque, while the others don't make it to 400. Also interesting is the spread of gear quantity. The Maserati has just six ratios to choose from, and the Lexus has a whopping 10.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.
