Language issue: what are hip-radiators (Lotus 72)?

Yes that cover shows Alboreto testing the 639 in 1988. Distingushed from the 640 by the twin engine air intake one each side of driver's head.

Watch the interviews with the designer. All is revealed.

.... A modified version of the F1/87/88C was initially used as a test mule for the new V-12 engine and the semi-automatic gearbox until the FERRARI 639 test car first arrived for testing in late 1988.

Here is a copy of Autosprint 28 1988.
It is from July 1988 and clearly shows the Ferrari 639 being driven by Alboreto in a strange seating position.

Another interesting development was that F1 had intended for Turbos to be banned in 1988. But somehow it was overruled and instead, they attempted to reduce the Boost and fuel limits of the turbos in the hope of making them uncompetitive. This led to Ferrari continuing with the 1987 turbo car rather than racing the 639.

In 1988 FERRARI did not continue with the 1987 turbo car. In 1988 FERRARI raced their new and updated F1/78/88C updated to conform to the new regulations, it futured new front and rear wings and a lower engine cover that is besides the modified new engine tipo 033A also plus the type 638 6-speed manual gearbox. 5 race cars were build for 1988 season, two were modified F1/78 to 1988 specification and three new for 1988 specification cars.

The Ferrari was a further development of the previous year's car, the Ferrari F1/87 . In favor of the rule change for 1989, Ferrari decided against a complex new development and only adapted the F1/87 to the modified rules for 1988.

Yes. "The (1988 -F1/87/88C) FERRARI was further development of the previous year's car (1987 - F1/87)". That is why in 1988 FERRARI raced the F1/87/88C and not the F1/87.

Michele Alboreto never tested the 639.
The Autosprint cover of July 1988 pictures Dario Benuzzi - long-time Ferrari tester for both street/gt and F1 cars - on the circuit of Balocco (Alfa Romeo private testing track).

[saviour stivala]

The '639' was tested by 3 drivers, Benuzzi, Moreno and Berger. A week just before the Australian GP Moreno tested the '639' at Fiorano. In 1988 Spain GP Berger was the only driver to use a turbo car, for tyre tests.

The back than so called "strange car" - the F1/87/88C with atmospheric V-12 engine but with chassis and gearbox the same as used on the standard turbo car (6-manual speeds), of course it was longer (distance between wheels) by 20/25mm, Autosprint called it ''F1/88A'' ''IBRIDO' (HYBRID). But it was an UNOFFICIAL name. It was first used during test at Fiorano in October 1988. Fiorano October 1988. - Berger - FERRARI 639 - best lap ---------. Morano - FERRARI F1/88A - ''IBRIDO'' - best lap 1' 12''10. Moreno - FERRARI 639 - best lap 1' 11''04. Moreno - FERRARI F1/87/88C turbo - best lap 1' 11''5. Moreno - FERRARI F1/88A ''IBRIDO'' did 14 laps on Thursday and 22 laps on Friday, a total 36 laps - 114km when he broke the engine.
