Lotus has made a 'major' step --
Jarno Trulli believes Lotus has managed to make a ``major step forward'' with its T127 car thanks to the big upgrade it has introduced for Barcelona.
Lotus Cars has secured enough investment from its new Malaysian owner, the automotive giant DRB-Hicom, to restore full car production at its Hethel assembly plant in the next few days, and continue build-up to the launch of the first of its new-wave models, the Esprit supercar due in showrooms before the end of 2013.
