Mercedes-AMG to launch high-performance electric cars

  Mercedes-AMG to launch high-performance electric cars Pure electric cars now in the works at AMG to supplement new hybrid models, Merc’s R&D boss has hinted“Are we going to see all-electric AMGs?’ said Mercedes R&D boss Ola Kallenius, “Why not? It is not a concrete programme at the moment, but it is conceivable. Besides we have been there before.

The charge towards the electrification of the automobile is well under way. Hybrids are 20 years old and well accepted. In the last few years, we have seen an influx of plug-in hybrid and EV options, but not all is ideal. At least not yet.

Despite the seemingly never-ending talk about these technologies, the fact remains that electrified vehicles still only represent a fraction of a fraction of total annual sales in North America. Most experts and consumers agree that fully electric cars are still heavily compromised. Their narrow range, which can vary wildly depending on climate and road conditions, limits them to urban areas. Plug-in hybrids are, in my opinion, the modern-day equivalent of Snake Oil; they are burdened by heavy batteries that provide limited electric autonomy. In many cases, plain old hybrids are more efficient.

The four-door coupe will be the first new Benz to electrify its inline six-cylinder engine with the new EQ Boost 48 - volt mild hybrid system.

The most recent electrification technology introduction, I’m convinced, will prove to be as impactful as the first hybrids to hit our roads. A 48-volt mild-hybrid system will be the answer to many of our immediate and long-term goals.

The 48-volt setup, which works in parallel with the conventional 12-volt system, consists of a typically rear-mounted battery (albeit a much smaller one than a hybrid), an electric motor/generator and other various related components. The extra juice serves not only to power the increasing number of accessories we’ve come to expect from modern cars, but also to do away with parasitic power losses. The latter generally involves belt-driven compressors, generators (alternator), pumps and more. As well, it can drive both turbochargers and superchargers, thus eliminating lag. Mild-hybrid technology also provides power boosts when required.

Mercedes-AMG A35 May Debut This Year With More Power Than Expected

  Mercedes-AMG A35 May Debut This Year With More Power Than Expected The milder version of Mercedes A-Class hot hatch could pack even more than the previously expected 300 hp. The new Mercedes-Benz A-Class will launch later this year with three new engines, but the real highlight of the range will take a little longer to premiere when the German brand will unveil the high-performance AMG variants of its compact model. According to Australia's Motor, even the less potent A35 AMG variant will allegedly pack around 335 horsepower (250 kilowatts) and 332 pound-feet (450 Newton-meters). Earlier rumors had indicated this powertrain would have closer to 300 hp (224 kW).

The EQ Boost starter-alternator is a key component of the 48 V system and not only serves as an alternator, but is also responsible for hybrid VLOG: юбилейный кабриолет Mercedes - Benz E-Class 25th Anniversary E400 Cabriolet - Продолжительность: 14:10 Roma Urraco 89 175

Continental projects that 48 - volt mild hybrid systems will account for 14 percent of global new vehicle sales in 2025, as sales of vehicles powered exclusively by And Mercedes - Benz is equipping the new in-line six-cylinder engine of the 2019 CLS 450 with its EQ integrated starter-generator system.

If we take the latest generation Mercedes-Benz CLS, the new inline six-cylinder engine does away with all belts. The air conditioning compressor, water pump and all other previously belt-driven accessories are now electrically powered thanks to a 48-volt setup. Mercedes’ brilliant marketing team went so far as to call the technology EQ-Boost, which makes it sound like a performance enhancement. In fact, EQ-Boost temporarily boosts engine output by a further 21 horsepower and 184 lb.-ft. of torque. Its integrated electric auxiliary compressor primes the turbocharger for an extra punch. It also handles engine start/stop functions and more.

This technology is clearly meant to improve fuel economy, first and foremost. While numbers are not yet available for the new 2019 CLS, the related efficiency benefits could reach as high as a 15% improvement in fuel economy. I suspect this number will climb as the technology evolves.

An Update for the 2019 Mercedes-AMG C 43

  An Update for the 2019 Mercedes-AMG C 43 The popular Mercedes-Benz C-Class will receive some changes for the 2019 model year, the current generation being on the market since 2015. The manufacturer notably announced details regarding the Mercedes-AMG C 43, which will be available in sedan and wagon body styles in Canada. First of all, its twin-turbo, 3.0-litre …First of all, its twin-turbo, 3.0-litre V6 will see its output rise from 362 to 385 horsepower, while torque will remain unchanged at 384 pound-feet. This engine will still be connected to a nine-speed automatic transmission and 4MATIC all-wheel drive. According to Mercedes, the C 43 will be able to blast from 0 to 100 km/h in 4.7 seconds (4.8 for the wagon).

This makes 48 - volt mild hybrids a relatively cheap, easy and lightweight way to get, as Gustanski It’s no wonder industry expert IHS says the market for 48 volt mild hybrids is expected to increase ninefold by Mercedes Brings Back The Inline Six With 408 HP And Marvelous New Technology.

What we mustn’t lose sight of is that internal combustion engines will be around for a long time yet in this scenario. Including 48-volt mild-hybrid components in cars is relatively inexpensive and so it’s no small wonder that many predict that 10% of all new cars will feature this technology by 2025.

I believe this is exactly what is meant by having one’s cake and eating it too. We get to keep our gasoline engines, get more power, reduce emissions and save on fuel. That’s a win-win.

2019 Mercedes-AMG E53 sedan brings straight-six power to the traditional sedan .
The final piece of the inline-6-powered, midsize Mercedes-AMG lineup has been added: the 2019 Mercedes-AMG E53 sedan that will use the same 3.0-liter turbocharged inline-six as the CLS53, and E53 coupe and cabrio. Producing the same 429 horsepower and 384 pound-feet of torque, it features the same 48-volt ultra-mild hybrid assist combined with a starter-generator and a small electrically-driven compressor in the intake tract to help reduce turbo lag.Power is fed to all four wheels via a nine-speed automatic transmission, the only one offered with this powertrain.
