Re: Wonderful little cars
It has devolved.
The original 1.0L 3 cylinder came to Toyota group from its Daihatsu division as the driving power inside the Daihatsu Mira aka Cuore/Charade. IIRC it first appeared on the 1998 Mira and really came to shine on the 2003-2007 Mira/Charade.
Compared to the Aygo, the Mira/Charade is a briliant city vehicle - no thrills, utilitarian, functional and most importantly zippy - 12s to 60, not the snail pace 15 you get from the Japano-French geriatric. It is also geared very low (same as the Daihatsu 2003 SIrion mk 3) so the 12s does not depict the real driving experience in city conditions - the performance in 0-30 is considerably higher than what can be expected from the 12s number (sub-4s if memory serves me right).
Its sole problem was the utterly inept marketing by Daihatsu in Europe compounded by internal restrictions inside Toyota group and the mandate of: "though shall address youf and pensioners and though shall not compete with the Yaris". So it did not sell around here anywhere near the levels at which the Mira sold in the far east (there it is outsold Toyota proper left right and center).
Compared to that (which are the Aygo roots), the original Aygo was a step backwards and this one is not an improvement either. I will take a 2003 Charade over an Aygo any day today, pity they do not make them any more.
In any case - it is surprising that Toyota are not shipping a Turbo version of it. A turbo for the 1L Daihatsu/Toyota 3 cyl has been available for ages taking its ~55-65 bhp (depending on sub-variety, exhaust assembly, etc) to nearly 100. Otherwise - I agree, the original unit is now way old in the tooth to be competitive with the new VW group small vehicles.
