Yes, and then some. The Merkava was designed from top to bottom top suit Israel's needs. Export, and the potential needs of customers were never considered. As a result, protection was prioritized over speed. Merkava's MK1 and MK11 had a top speed of 30 mph and weighed 65 tons. Meanwhile, the Leclrec is 9 tons lighter and has "one of the best power to weight ratios and top speed of any modern tank".
First of all I'm pretty sure the MK.II is faster then 30 mph, but I can't recall just how much faster. I'll ask next month when I'm on reserve duty.
But more importently, you are comparing a tank from the '80's to a tank from the '90's. And that's with base data. We still don't know how much the weight and after that the performance of the Leclerc change once you remove the autoloader and place a fourth crew member and additional armor for him. If you don't add additional armor it's still fast, but not as protected as comparable tanks.
If you get a MK.II and after that buy MK.III you still have a good tank all throught the '80's without relying on the old Centurions or buy aging M60's, and you also have a nearly fully compatible logistics system, since both generations have plenty of parts that fit both, instead of trying to supply a WW2-era British tank, a cold war American, and a '90's French.
The Leclrec has a range of over 400 MPH. I also bet the Leclerec's 8 cylinder engine is more fuel efficient than the Challenger's 12 cylinder. Then factor in less wear on bridges, roads etc.
The difference of wear of bridges and roads is negligable.
That is true, but alot of French equipment does fit SADF needs. I am sure that a hypothetical "total package" South African purchase of bush war oriented Leclrecs, Mirage 2000-5s, Mistral manpads, Exocets, and french radios would give the SADF excellent equipment at an attractive savings.
Sure, I would want the very best, "cost no objection" equipment, but I would also need to be concerned about other national needs balanced against realistic threats. South Africa is not facing a "Fulda Gap" type scenario, so the global "par excellence" tank may not be needed. Likewise, German submarines may well have better performance than Agostas, but are they worth the additional cost given other national needs? Maybe, maybe not.
It's possible, but so is doing the same with American or British equipment.
