Henley-on-Thames, England – Get ready. With the third-generation “new” Mini just out of the gate, we can expect parent company BMW to starting spitting out variations with the speed of a greased-up Gatling gun; and the culling of the old models with equal vigour.

We’re here in England to sample the second version of Mini to be built on this all-new front-drive platform that will be underpinning all future Minis and numerous BMWs.

It’s called the Mini 5 Door and is aimed at those who seek more utility with their Mini-ness. Compared with the three-door Coupe, it gets a wheelbase stretch of 72 mm (which translates to an equal increase in rear legroom), is 161 mm longer overall and the roofline is 11 mm higher. Luggage capacity behind the rear seats increases by 30 percent.

Mini is advertising the 5 Door as a five-seater, but don’t be fooled. I don’t think you could even squeeze three kids in the back seat with a clear conscience. Maybe three of the Seven Dwarfs, but even then they’d all be grumpy.But wait. Haven’t we heard this story before in Mini-land? What about the Mini Clubman wagon-thingy that was introduced as a 2008 model? Uh, it’s just been killed off.

Okay. What of the five-door four-seat Countryman? That is now only available in the top $29,900 Cooper S ALL4 all-wheel-drive trim. With its elevated ride and roof height, Mini wants us to think of it more as a crossover anyway.

The 2015 Mini 5 door will arrive in Canada late 2014 in two variants – the three-cylinder 134 hp Cooper 5 door at $22,240 and the four-cylinder 189 hp Cooper S 5 door at $26,740. Both are turbocharged and both ask for premium fuel. For comparison, the 2015 Mini Cooper three-door hatch starts at $20,990 and the Cooper S at $25,490.

Mini is advertising the 5 Door as a five-seater, but don’t be fooled. I don’t think you could even squeeze three kids in the back seat with a clear conscience. Maybe three of the Seven Dwarfs, but even then they’d all be grumpy. That said, it’s perfectly suitable for two adults. Once through the smallish door openings, you’ll find nicely contoured seats and plenty of headroom. At nearly six-feet tall, I could easily “sit behind myself” with the driver’s chair adjusted comfortably.

I found the fabric front seats of these testers to be terrific. They also sported cool tartan bolsters.

Initially this lengthened Mini looks a little unusual to the eye, but after a day we began to appreciate its well-integrated lines and chic profile.

The Mini’s new dash sticks to the circular script inspired by the original car’s round central speedo, but materials and build quality are vastly improved. This is the first Mini I’ve driven in recent memory that hasn’t been plagued with a persistent dash rattle. Finally, it feels like a premium car in here.

Things have been moved around a bit from the last model. The window switches are now on the doors and there is an analogue speedometer (along with the tachometer) mounted on the steering column. Before, we either tried to decipher the indicator on the outer edge of the big central circle or looked at the digital speedo readout in front.

The manhole-sized central display now shows all the menus and info called up through the iDrive controller, replacing the fussy little joystick from the last model. The interface is easy to use and the graphics are great. These S cars had the crystal-clear 8.8-inch screen and the on-board navigation was excellent. The whole shebang is ringed a giant LED glow stick that changes colours depending on the drive mode or function you’re accessing. Turn down the temp and the left quadrant turns blue for a few seconds. In sport mode it apes a tachometer. Quite fun, really.

I didn’t get a chance to really lean on the Cooper S 5 Door as the heavily trafficked roads prevented any real hooning (as did the fact that the steering wheel was on the wrong side and the hedgerow-lined lanes left zero room for error), but as far as I could tell this lengthened Mini felt pretty much like the 3-door Cooper S.

The fact that many of the rough edges have been smoothed out on this third-gen car does not take away from its essential Mini-ness. The steering is still direct and super quick – but not as nervous. There is less torque steer and the cabin is quieter. With the available adaptive damping (my advice: pony up for this), the Mini now has an acceptable ride. Even in the firmest Sport mode it doesn’t crash over the rough stuff like the previous model. But it sure does handle. The Mini is still one of the more entertaining devices for unraveling a twisty road.

The Cooper and Cooper S come with standard six-speed manual transmission, but these cars were fitted with the optional six-speed automatic transmission. In the Cooper, it’s an additional $1,400. Only for Cooper S is the $1,650 Steptronic Sport with paddle shifters. It shifts smoothly and responds to paddle inputs with useful alacrity.

There are three drive modes – Green, Mid and Sport. Green dulls the throttle response and optimizes the climate control for max efficiency. If fitted with the auto tranny it enables a coasting function wherein the engine will decouple from the transmission and drop to idle at speeds between 50 and 160 km/h. Sport mode sharpens the throttle response, wakes up the tranny, gives the exhaust more bark and firms up the steering and the dampers if fitted with optional Dynamic Damper Control.

We didn’t drive the three-cylinder Cooper 5 Door model, but having experienced the 134 hp, 162 lb-ft (from 1,250 rpm) turbo three-pot in the regular Mini hatch, I can attest to its terrific power delivery, smoothness and fabulous fuel economy. For those looking at this interesting new offering from Mini, I’d suggest the 1.5L three cylinder is all the engine you’ll ever need.

The Mini 5 Door can be optioned up to luxury car levels, now that such things as camera-based adaptive cruise-control with forward collision mitigation, dual-zone climate control, full LED adaptive headlights, park assist, Harman/Kardon sound and head up display are available. Similarly, it is fully customizable with a dizzying array of colours, wheels, seat upholsteries, interior surfaces, decorative trims for the mirrors and bonnet stripes.

As far as variations on the Mini theme go, this new 5 Door stands up pretty well to scrutiny. It looks good, it’s much more useful than the quirky Clubman and avoids the bloated crossover-ness of the Countryman. Additionally, with this third-gen Mini being marginally bigger and a whole lot more refined, it makes a fine jumping off point for all future Minis.
