All-New Mercedes-Benz CLA Will Be A Technological Tour De Force

Mercedes-Benz intends to turn into a completely electrical automaker sometime, and the following CLA will carry that goal a little bit nearer. To be out there as each an EV and a hybrid, the following CLA will probably be constructed atop the Mercedes Modular Structure (MMA), introducing 800V know-how to a road-going Mercedes for the primary time. Just like the Imaginative and prescient EQXX idea, the brand new CLA makes use of a extremely environment friendly silicon carbide inverter for its electrical motors, developed completely in-house by Mercedes engineers, however there are a number of different spectacular options to the brand new structure, which in hybrid type will characteristic a model new engine and gearbox, too.

Energy Dense And Environment friendly

The usual setup will see a single completely excited synchronous machine motor fitted on the rear axle. This 200 kW/268-horsepower motor is linked to a rear-mounted two-speed transmission, very similar to the Porsche Tacyan. On 4MATIC fashions, a second 80 kW/107-hp motor is added to the entrance axle and might be immediately decupled to cut back entrance axle effectivity losses by 90%, however there’ll nonetheless be house for a frunk. This entrance motor will solely be lively when traction is misplaced or the motive force calls for most energy output. In 1st gear, the transmission has a ratio of 11:1, with second gear at 5:1.

This permits a prime pace of 130 mph (comparable with the present CLA), and the transmission can modify shift factors primarily based on mode and demand to maximise effectivity or efficiency as wanted. Mercedes claims a battery-to-wheel effectivity charge of 93% on lengthy journeys. A part of that is because of a predictive power administration system that takes under consideration highway situations and visitors, a extra environment friendly warmth pump, and a regenerative system that, whereas adjustable, is designed to deal with the majority of the braking.

Vary And Charging

Mercedes has carried out a number of improvements to make this doubtlessly probably the most livable EV in its class, together with a extra environment friendly warmth pump, with the Idea CLA Class able to an estimated vary of 466 miles on the WLTP cycle. EPA figures are sometimes decrease, however not by very a lot. The navigation system can plan the quickest and most handy route, with the ECO Assistant driving mode able to controlling power consumption by getting ready for upcoming roundabouts, bends, junctions, hill gradients, and pace limits. As well as, the Electrical Intelligence system from the EQS and EQE seems right here, serving to direct drivers to the very best charging stations primarily based on route, out there shops, and cost features. As well as, “the system schedules stops to optimize the general journey time,” says Mercedes, including that “typically, two shorter, higher-capacity charging classes could also be preferable to a single longer cease.”

Ideally, you’d need to discover a DC quick charger, which might allow speeds of as much as 320 kW. Within the idea, a 10-minute cost yields as much as 186 miles. Mercedes claims that the 85-kWh (usable) battery’s consumption is a report 5.2 miles/kWh and that that is as momentous for EVs as a 1.0-liter engine is for combustion effectivity. For comparability, the 2025 Lucid Air Pure, the present manufacturing EV benchmark, does 5 miles/kWh. Mercedes additionally touts much less uncooked materials use because of the addition of silicon oxide to the graphite anodes, growing gravimetric density by as much as 20%. The automaker additionally guarantees “complete precautions to forestall thermal runaway,” which has explosively impacted two Mercedes EVs in Britain and Korea this 12 months. Bi-directional charging can even come to the CLA, so Mercedes is throwing every part at this one.

The Hybrid

A part of the brand new Household of Modular Engines (FAME), a brand new 1.5-liter Miller cycle four-cylinder engine (dubbed M252) will probably be transversely mounted within the automotive and linked to a 48V hybrid powertrain with its 1.3-kWh battery. This may characteristic an electrical motor with as much as 29 kW/27 hp of drive energy built-in with an inverter and mixed with a brand new eight-speed dual-clutch transmission known as 8F-eDCT. Whole mixed output for the US mannequin will probably be 188 hp, and the hybrid will arrive shortly after the EV fashions, though a date for that’s but to be confirmed. Mercedes has put a variety of effort into the refinement of this hybrid, selecting 4 cylinders as an alternative of three for superior NVH (noise, vibration, harshness) qualities. The automaker additionally says that the hybrid can preserve electrical coasting at speeds of as much as 62 mph and that the beginning/cease system’s operation is almost imperceptible.

Apparently, America received’t be getting the brand new Audi S5 in mild-hybrid type as a result of US patrons are uncomfortable with the engine switching off at freeway speeds and since the cease/begin system and the switchover between combustion and EV energy are too jerky. Equally, VW is not promoting DCTs in US-market SUVs as a result of patrons discover them too sharp. Hopefully, Mercedes has discovered a manner of addressing considerations like these. With extra info steadily being made out there, we anticipate a reveal earlier than the top of this 12 months, doubtlessly on the LA Auto Present, in any other case early in 2025.
