Generally, Cars from Enstone have been good performers. Last year has been an exception where they went too adventurous; key people left the team; Budget constraints and importantly an under performing PU, probably contributed to lackluster performance.
Now here is E23 (of course renderings), suddenly evoking a lot of positive feelings. A neat design, housing, probably the best PU in the competition and things looking upward. The front suspension and wishbone designs completely resemble the W05. Although the design looks much more conservative on cooling front, if the results are positive, expect more aggressive modification as the season progresses. They seems to have lost a lot of sponsors and I hope budget constraints wouldn't stop them from challenging for good results.
Purely looking from design perspective, this cars looks every bit a top contender and could again bring Grosjean back in contention as a top class driver.
