In kaj si hotel povedati?
Roverjev K motor iz začetka 90ih je tudi cel iz aluminija. 1.8 motor s 108 kw ima reci piši 82 kg(brez tekočin). In to pred skoraj 20-imi leti.
The Toyota engine is now established with Lotus and one would wish this amazing company the best of luck with it in the US, given that the emission work has been done, however it seems very strange to offer the engine in an Elise here. In its favour, the Toyota engine does boast an "almost" headline grabbing 190 bhp and is very cheap for Lotus to buy. Against it though, it is a short stroke engine which consequently produces poor torque 133 lbft, only 8lbft more than the standard 118bhp k series and the Toyota has to be revved hard to get there, max torque coming in at 5800rpm as opposed to the Ks peak at just 3000rpm! What is more the Toyota only revs to 8250rpm which hardly justifies the short stroke design. I heard that Jeff Grose busied himself during the launch of the Toyota engined Exige, showing journalists, power and torque curves which he claimed reasonably equated the Toyota"s output, with the old VHPD. This exercise entirely missed the point - the VHPD"s performance is dreadful and that were it to be developed properly "by Rover" even the existing cams would give a solid 200bhp and 150lbft of torque @ 4000rpm, enough to comfortably beat the Toyota and be a much easier drive. Furthermore since the Toyota is so heavy " 127kg, dry as opposed to 82kg for a dry VHPD; - that"s a 54% increase in engine weight, the power to weight ratio of the Toyota is poor. In fact given that the new Elise 111R and Exige S2 have seen their kerb weights bloat to 860kg, even without the plethora of extras which most of these cars now seem to have [these send the kerb weight to 925kg "equivalent" to a conventional steel bodied Rover 25 !!!!!!!!!!!] this gives a power to weight ratio of 218 bhp/ton, equivalent only to the old Elise S1 160, which again was a poor non Rover engine but nonetheless had more accessible torque and therefore more grunt than the new Toyota engined cars
Je treba še kaj dodat?
Mislim, da je pametno da se debata o Lotusu, ki sem jo začel jaz, konča.
