This is the latest new Porsche, the Macan. Yes, we know, it\u2019s hard to keep up. The company didn\u2019t make an SUV 10 years ago, but now it\u2019s got a second one under its belt.Little brother Macan joins big brother Cayenne - the theory perhaps being that in this austerity day and age you might want your Porsche SUV in slightly smaller and less in-your-face format. Never mind that its name sounds like a tropical type of nut, this is likely to become the best-selling Porsche.Shown in a single, tricked-out turbo format here in Tokyo - the main launch was in LA, which we decided to give a miss this year in favour of Far Eastern promise - the Macan\u2019s hardly going to rock the boat in terms of style.But it isn\u2019t a bad-looking thing for an SUV. It keeps those familiar Porsche cues - the 911-a-like face and that softly surfaced, pronounced rump. We loved the massive clamshell bonnet, which rises up leaving the lights left in place, like the first-gen BMW mini. And we love the rear lamps, which are simple LED bars fixed inside a carbon-detailed unit on this show car. Very 21st century.Overall, it looks like an SUV worthy of the name - in that it\u2019s sporty. It looks really low, squat and with a good deal of intent for an SUV. It might not quite have the visually arresting quality of a Range Rover Evoque, but nor is it quite as cartoonish.Step inside the Macan, and if you\u2019ve been in a 911, Cayenne or Panamera you\u2019re going to feel at home. On the dash are three - rather than five - gauges. There\u2019s that familiar Porsche touchscreen in the centre and a huge bank of switches, flanking the gearlever, a la Panamera. What we did really love is that the steering wheel\u2019s the same one from the new 918 supercar - minus some of the crazy buttons for controlling the electric drive system.READ: Porsche 911 Carrera 4S reviewThe space in the back is hardly commodious, but will easily accommodate a couple of small kids, and the boot\u2019s bigger than the Evoque\u2019s is. The Macan\u2019s got the small, well-to-do family thing all covered.Underneath - the eagle-eyed may have spotted from the styling - the Macan\u2019s based on an Audi Q5. That\u2019s not necessarily a bad thing, and Porsche assure us it\u2019s been completely re-engineered and will feel like a Porsche.The turbo version of this Motor Show car features a new, 3.6-litre twin-turbo V6 but will be good for a sub 4.8 second 0-60 time. Handy if you want to make fido and the kids feel sick on the school run.We bank that the big seller will be the 3-litre diesel - the same one that can already be found doing service in the Cayenne. There\u2019ll be smaller petrols too - and expect the familiar normal, S, Turbo and somewhere further down the line GTS badging.Of course, your primary reason for wanting a Macan is probably that it\u2019s going to drive like a Porsche. With options that include Porsche active suspension management (PASM), Porsche vectoring control and carbon ceramic brakes, it ought not to be a disgrace to the family bloodline.If you live in a well-to-do metropolitan area, expect Macans to start to clutter the roadside outside your local primary schools and Starbucks come mid 2014.
