Some thoughts on the new #twingo
The new Twingo compared to the original is slower*, larger but less spacious and more claustophobic, heavier, with a larger front overhang (and steeper windshield rake..) despite the lack of engine. Some are unavoidable for an EV, but is this progress?

*vs the D4F, ~same as D7F

MQ-28 Ghost Bat and MQ-25 Stingray size check - if you see them in isolation the much smaller Ghost Bat appears larger than MQ-25 due to its shape, the reality is different

Η προκύρηξη ήταν μέσα στο roadmap που είχε ανακοινωθεί εδώ και καιρό, όμως η προθεσμία απο την προκύρηξη μέχρι την λήξη υποβολών είναι μόλις 2 εβδομάδες (!).

First official image of the Audi moment 2.0 concept.

This will signify the new design language for Audi. Looks a bit like a TT- jaguar hybrid but the surfaces are resolved and clean ("strive for clarity" is the slogan). Not as iconic as the TT or Avus but a huge improvement

If you were disappointed that the Tuthill Singer Vehicle Design All-terrain Competition Study (ACS) was abruptly shut down by Porsche and vanished, maybe you should look more carefully at Tuthill's '911 based' Meyers Manx LFG wheels, suspension/pick-up points and high sills

Are fighter jets a relic of the past? Apparently not, any country that rush to retire or ignore them may get a nasty surprise.

Same for ignoring any other assets, but when people advocate ex FPVs instead of fighter jets, they're usually not pro FPV but just against fighter jets

What Ukraine managed to do with operation "pavutyna" ("the web", interesting name!) is a paradigm shift, not only because of the result (40 strategic aircraft damaged) but for the method.

It took ~18 months to plan and the footage of embedded drones on trucks is surreal

Singer wasn’t the first, but it’s by far the best at ‘restomoding’—a whole new way of car production. It may look easy, but only
a few companies get it right, and probably only Singer does it at scale.

*Note the complete absence of Porsche badges on the new Carrera Coupe ..

Μια μακροσκοπική παρατήρηση με αφορμή την πορεία της Delian. Στην Ελλάδα, στον τομέα της τεχνολογίας και ειδικότερα σε hardware, κάθε σοβαρή εταιρία με την παρουσία της και μόνο, κάνει πιο εύκολο το πεδίο για κάθε άλλη νέα -και σοβαρή- εταιρία. Ισχύει φυσικά και το ανάποδο.
New USV from Delian Alliance Industries
