The new BMW 335is is available in either Coupe and Convertible form and from what it looks like so far it’s a model destined for the North American market only. It’s basically a sportier and more powerful version of the 335i.

That’s not really that much of a bummer, as you can essentially just equip your bog standard 335i here with a tune from BMW Performance that boosts the engine to the same specs as the 335is – 320 horses and 450Nm of torque.

It’s essentially the same output as what you get in the 740i. But this new model has been added in the US at a time where the standard 335i without the “s” at the back will have its N54 twin turbo replaced by the N55 single twin scroll turbo that produces the same output as the outgoing N54 non-s engine.

The highest output factory standard version of the N54B30 so far is the one in the Z4 sDrive35is, which gets 335 horses and 450Nm, with a 50Nm overboost so it can peak at 500Nm depending on conditions. The 335is also have the 50Nm overboost feature.

Look after the jump for hi-res photos from a media test drive that BMW had in Portugal at the Estoril track recently, as well as two videos and a full press release with detailed specs.
