The 415bhp Mercedes-AMG A45 S Will Do 0-62mph In 3.9 Seconds

Mercedes has revealed the new A45 and CLA45, both available in more powerful, more capable 'S' form

The Mercedes-AMG range has grown by four models. Affalterbach has just rolled the new A45 and CLA45, both of which are available in even hotter S trim.

The base versions aren’t exactly sluggish: each has 382bhp to play with from a new AMG 2.0-litre inline-four turbo engine, giving a 0-62mph time of 4.1 seconds in the CLA, and four seconds dead in the A45. Go for an S, and the power figure jumps to 415bhp, chopping a tenth of the 0-62 while increasing the electronically-limited top speed from 155mph to 168mph.

It is possible to option the limiter increase in the non-S cars, but really, it’s the shoutier model you want. Not just for the increase in power: although both versions of the new ‘45 ‘M139’ engines are designed to feel N/A like, the S should feel more so, with peak torque of 369lb ft made at 5000-5250rpm compared to 354lb ft felt at 4750-5000rpm in the ‘basic’ cars. The S cars meanwhile make peak power at 6750rpm as opposed to 6500, although whatever you go for, there’ll be a zingy 7200rpm redline to enjoy.

The whole unit is flipped 180 degrees relative to both the old M133 ‘45 engine, putting the turbocharger at the rear of the block. This shortens the required ducting, reducing weight and spool-up times.

Further helping the M139 when it comes to responsiveness, the twin-scroll turbocharger itself has - like the turbos used in the AMG GT63 S 4-Door - roller bearings.

Power is sent to all-four wheels via a new eight-speed dual-clutch automatic gearbox. The four-wheel drive system has a new rear differential packing a pair of multi-disc clutches, meaning torque split can be varied between the two wheels at the back.

Exactly how the four-wheel drive system behaves depends on what drive mode you’re in, and also whether or not you’ve enabled drift mode. Yep, the A45 and CLA45 will let you engage in sideways tomfoolery, provided you’ve either opted for the S or optioned the base model with the AMG Dynamic Plus package.

Whichever A45/CLA45 you go for, three-stage adaptive dampers are optional. When it comes top stopping, base ‘45s have four-piston monoblock front calipers teamed up with 35mm discs, with single-piston floating calipers squeezing 330mm rotors at the back. The front discs on the S models at 10mm bigger, and they’re paired with six-pot calipers.

Pricing hasn’t been revealed yet, but to give you an idea of how much the A45 and CLA45 might cost, you had to stump up £41,875 and £44,695 respectively for the last two. The current A35, meanwhile, is £35,580.

You know that hot hatch had a long history of making power for a small 3 to 5 door car. Now manufacturers asking about theyself one thing, how long this could last?

0-60 in 3.9 seconds in a hot hatch… that’s insane!

I really like the looks on CLA45 and now with quad exhaust it looks even better especially in designo grey. And also #bringbackrealovalpipesonamg

This could possibly be considered the first modern Hyper Hatch. I don’t think there’s been a bonkers Hyper Hatch like this since the V6 Clio and the Escort Cosworth.

Definitely bound to go down as a future classic like the beloved Clio V6 and Escort Cosworth, in my opinion. I mean, 415 hp from their new Inline 4, developed by AMG’s crazy scientists? Thats gotta be mind-blowing news right there. Just to imagine what the rawness of it will feel like while driving this. One thing I can tell is, the future hot hatch wars are gonna be exciting…

that’s not a bad thing at all! I think it will bring more hatches to north America if this goes on sale soon, and who wouldn’t want that.

I’m not a huge fan of hatches but I NEED THIS! The best looking hatch in a long time! What do you guys think about the styling?

Honestly i think (like most modern cars) its trying way too hard. Super overstyled in my opinion

A hot hatch that can beat an f40 off the line. What is this world

Really liking this hatch (maybe..despite its “invasive” pop and bang nature). My biggest concern is the reliability ! I mean, the previous generation was already known to blow its turbos quite easily, I’m really worried for this one :/

911 Turbos has that much power not long ago, in fact isn’t that what a Carrera S makes nowadays?
