French carmaker Renault, one of the first mainstream companies to move into the electric car market, is teaming up with a home energy start-up, Powervault, on a project that could make home solar power systems affordable and simultaneously give a new life to older electric car batteries.

Test Drive

A compact German runaround with a budget price tag could be the latest addition to the growing selection of small electric city cars. The e.Go Life is billed as a four-seater vehicle with a small electric motor that's perfectly suited to urban driving. The price is announced at €15,900 (excluding government incentives that may apply).

Travel routes

Between Nice and Menton the mountains plunge sharply down to the sea. Running along these heights are three famous routes: the Grande Corniche, the Moyenne Corniche and the Basse Corniche. The first affords the most stunning views, climbing to 1,476ft/450m. The second offers beautiful vistas along the shore; while the third provides access to the coastal resorts.
