Toyota-powered Smart Roadster: Spotted
This one-off build combines Smart's tiny two-seater with a 145hp 1.3 sourced from a Starlet...

Remember when the Smart Roadster Brabus was launched? That’s a car that had a lot going for it. It was a tiny, rear-drive two-seater that weighed less than a Mk1 Ka, and it had an enthusiastic, mid-mounted turbocharged triple that made all the right sounds and provided more gusto than its 101hp output suggested. But the little Roadster Brabus defied its size with a comparably high list price that placed it close to the Mazda MX-5, plus, its highly-strung engine needed fully synthetic oil and a service every 7,000 miles, so the car could never compete with the cheap as chips Mazda. That it had other shortfalls, like a brittle ride, hesitant automatic gearbox and slow ratio steering, not to mention very limited storage space, sealed the Brabus’s fate and it remained a niche choice in Britain up until its demise with all the Smart Roadsters in 2005.
Yet it was still a very good car. Actually, in the right circumstance it was brilliant. It had vintage sports car dimensions so even the narrowest of country lanes felt like a race track. Its steering, although sluggish to respond, offered genuine feel. And that dinky chassis – itself a stretched Smart ForTwo structure – had good balance thanks to its squat stance and midship layout. Those who had one for long enough to see past the foibles could appreciate its charms, potential for entertainment and, well, purity. Such a shame not enough of us bought one to secure its future and potential further development.

Perhaps Smart should have put its higher-output concept Roadster into production as a halo model to attract more attention to the range. The Smart Roadster Coupe V6, as its name suggests, had a six-cylinder engine and was built in just 10 examples (none were sold and only two survive in museums) ahead of the Brabus model’s launch. The car’s engine was made by essentially joining two blown triples together on a common crankcase to create a new 1.3-litre motor offering 175hp and 162lb ft of torque. It transformed the car into a serious performance machine with a sub-six-second 0-62mph time and 140mph top speed. That in production form would have certainly garnered wider appreciation, surely, but it was never to be.
This makes today’s Spotted all the more interesting. Here we have a Smart Roadster, dressed in Brabus specification, that's powered by a turbocharged 1.3-litre engine with 145hp. No, not from a V6 like the concept, but rather a four-cylinder sourced - we think - from a Toyota Glanza V. As far as can be seen, it’s been integrated into this custom Roadster to a very high standard; it's described as ready for “club events such as hill climbing and sprinting” by the seller. It uses a five-speed manual gearbox sourced from the Toyota, which in itself is something of interest because the Brabus was auto only, and has an accompanying custom-made pedal box.

Backing the seller’s claims for this high-quality build is a first place finish at Italy's Smart Times – no, we hadn’t heard of it either – in 2011, a third place finish in a tuning competition at the same event and then a second in Belgium’s version of the same thing. If you need more to boost your confidence that it won’t blow up once you drive off the forecourt, the dealer is throwing in a 12-month warranty, tax and a full MOT.
OK, so the elephant in the room: it’s twenty grand. But let’s not forget that list of attributes that made the original model so good, and the cracking performance offered by the concept. This car essentially combines those characteristics into one machine, so as far as Smart Roadsters you can actually buy go, it's got to be the best of the lot. Hasn't it?

The Roadster Coupe is such a good looking car and as an absolute hoot to drive!!!
Article is not quite correct, as the gearbox isn't an auto, but rather a 6-speed manual with automated clutch an auto function.
As with all of these types of gearboxes from the early 00's you need to think like the gearbox to use them. Once you learned this they aren't all that bad as everybody believes. Not saying they are good, they just aren't as bad as JC and others keep claiming.
I adore the Roadster Coupe and have driven a couple of them with 95% commitment to buy...
The main problem is that I don't need one... Certainly not enough to justify a 4th car at the same time.
I dream of sticking one of these into the back of one


Being the Starlet engine can this be wound up to big power like the Glanza?
Wonderful little car. Felt like we were doing 100mph, when the speedo was actually saying 100kph.
Unfortunately, the gearbox killed it for me. Woeful, truly BAD CVT. If they'd replaced the gearbox with a decent manual, and as a secondary request, switched to a decent 1ltr non-turbo, would have been perfect.

WRT the bike engine conversions - they are by a number of accounts not a whole lot of fun to drive. Needs tons of revs with not a lot of torque
Yeah nice conversion (on the face of it), but really odd choice of engine.. Agree a 2ZZ-GE with short ratio 6-speed and LSD (use MR2 bits) would seem the more appropriate choice. Of course the owner clearly liked his little Starlet engine!

But it was fun in all other respects!
I had a standard 80bhp car, then upgraded to the 101bhp Brabus. Wonderful things, and an absolute hoot to drive.
I didn't sell the Brabus because of the gearbox, and you really do learn to work with it, or around it at least. But the box is probably the reason I wouldn't buy another. It is very flawed.
The attention and smiles they get is just great. Everyone loves them. It's just one of those happy cars that's impossible to dislike.
I did wonder if a 1.0 Ecoboost would fit. Similar size and power and character as the original, but just a few more horses. And a manual box! I don't think the Toyota conversion works for me. It's too aggressive.

I'd find it highly unlikely that an iron-block turbo engine of 80's vintage would be lighter than an all-alloy engine from the 90's.. I've seen (not personally) a couple of MR2 swaps where the 4A-GE (NA 1.6L, lovely wee engine, also loves revs) was swapped for a 2ZZ-GE, and there is no weight penalty at all, and they seem to be very similar in overall dimensions. Granted, the 'performance' Toyota G engines may be slightly wider in the cylinder head than F engines (wider valve angle for improved higher rpm air flow).
Not disagreeing its a 'bad' engines choice, just I'm well aware of the effects of combining relatively SWB mid-engine cars and 'boosty' turbo engines..

The block and head is definitely bigger, plus, the additional turbo and intercooler etc. have a place to reside, as they did when the car had it's original engine.
B16 would suit me!
Nah, 4A-GE 20V Black top stuck to Celica 6-speeder

This looks like a very neat conversion, though you lose all the boot space and I'm not keen on all the excessive red highlights in the cockpit either. It's a huge stretch at £20k, I can't see it getting sold any time soon.
