Russian Grand Prix: Hamilton on pole for Mercedes

Hamilton (r) has pole in Russia followed by Rosberg (l) and Bottas (c) Amid tight security thanks to Russia’s ongoing spat in Ukraine, and a muted appetite for exuberance after Jules Bianchi’s dreadful crash with a JCB on track last weekend, the rest of the F1 circus seems to be on normal duty, with Hamilton’s Mercedes taking the front row and Hamilton dominating proceedings in qualifying to secure another pole position. But it wasn’t necessarily going all Mercedes’ way, with Bottas stringing together a very quick lap in the dying moments of final qualifying that looked like it could propel him in front of the Mercedes duo, until he lost traction at the end of his flying lap and had to settle for third spot in tomorrow’s race. Joining Bottas on row two is Jenson Button and his McLaren after a strong qualifying, and Daniil Kvyat – at his first home Grand Prix – managed to secure a very impressive fifth spot for Toro Rosso. Kevin Magnussen in the second McLaren would have been on row three in sixth spot but gets a five place penalty for a gearbox change.

Tesla recalls Roadster for short in power cable, fire risk

Tesla Motors is recalling its electric Roadster 2.0 and 2.5 models because a power cable may short and catch fire. The 12-volt cable, located behind the right-front headlight, could rub against the carbon-fiber paneling causing the cable to short, begin smoking and possibly catch fire, Tesla said. The cable is part of a backup system that powers the headlights, taillights, turn signals and airbags if the primary 12-volt cable fails.
