Mercedes-AMG Has Partnered With Garrett To Make No-Lag Electric Turbos - Car Throttle
AMG has detailed its next-generation turbocharger, which will be spooled up by a small electric motor
With V8s set to make way for inline-fours in Mercedes-AMGs range, Affalterbach needs to start squeezing a ridiculous amount of power from tiny engines. With a specific output of over 200bhp per litre, the M139 that powers the 45 line-up is a good starting point, but its going to need some help, which will come in the form of electricity. Were not talking about hybridisation, though. Nope - AMG will be sticking motors inside its turbochargers. Mercedes performance arm already has an e-turbo in the final stages of development, which will be aided by a four-centimetre electric motor. Its integrated onto the charger shaft, sitting it between the turbine and compressor wheels. Powered by a 48-volt electrical subsystem, its able to spin the compressor wheel before the exhaust gasses hit it. This leaves Mercedes free to extract more power from small engines without creating big dollops of turbo lag. The system - which is made in partnership with Garrett Motion and uses F1-derived technology - could kill of lag entirely. The new turbo is capable of spinning at up to 170,000rpm, slightly faster than the more conventional snail used in the M139. The turbo, its motor and all the associated electronics are hooked up to the engines cooling circuit to ensure nothing overheats. We have seen electric compressors used in production cars before, and a few from Mercedes, with some of its 3.0-litre inline-sixes boosted by 48-volt-powered devices. However, these setups arent directly comparable, since they involve small motor-driven units working together with regular turbochargers. The new e-turbo is a very different beast and stands to completely change the character of turbocharged cars as we know them today. The impending death of AMGs V8 remains a huge shame, of course, but these fancy new turbos will go a long way towards making up for the 4.0 litres eventual ditching.
Would You Spend £65,000 On A Mercedes-AMG GLA 45 S? - Car Throttle
UK pricing has confirmed for the GLA 35 and GLA 45 S, with the spendiest version of the latter coming in at £64,775
With the Mercedes-AMG A45 S coming with a price tag as attention-grabbing as its 0-62mph time, it was inevitable that the bigger GLA 45 S would cost an even more eyebrow-raising amount. Sure enough, in top-spec Plus trim, it weighs in at £64,775. Ouch. By far the most expensive version of the 45 family weve seen so far, the GLA 45 S Plus works out roughly £8000 more than an A45 S in the same spec. If the AMGd A-Class is anything to go by, though, there wont be many cost options on the menu to inflate the chunky starting price of the Plus much further. The Plus pack provides adaptive dampers, 21-inch wheels, multibeam LED headlights and an aero package. Inside, thusly equipped cars come with a panoramic sunroof, electrically adjustable multi-contour seats, and a Burmester audio system. On the safety front, blind-spot assist and traffic sign assist functions are fitted as standard. If youre happy to do without all that, the base GLA 45 S is £58,755. Thats as cheap as it gets in the UK - mirroring the same setup in the British A45 and CLA 45 ranges, the less powerful non-S version isnt available here. For anyone wishing to spend less on an AMGd GLA, theres the GLA 35, starting at £43,565. Spec the Premium package with its 10.-25-inch digital cockpit, augmented reality navigation, keyless entry and bigger wheels, and that figure rises to £46,065. Finally, £50,000 gets you a GLA 35 with Premium Plus, adding adaptive dampers, AMG aero, even bigger wheels, a Burmester sound system and much more besides. This trim grade also opens up the option of the Driving Assistance package, which adds an extra £1495 to the price. Both of the AMG GLAs are available to order now, with initial deliveries starting this summer.
