Rare Isdera Imperator 108i flexes its considerable muscles

The Isdera Imperator 108i is a remarkably rare supercar from the late 80s and early 90s. Born of a Mercedes-Benz concept car, it's powered by a range of AMG-developed V8s, with five to six liters of displacement, depending on the engine. The example shown here, lapping the legendary Spa-Francorchamps circuit, features the most potent 6.0-liter V8 available. And rather than just being driven about on a perfectly clean racing line, it's freaking power sliding!
Yes, there's something eternally childlike about a wedge-shaped supercar from our formative years being flung about a Belgian racetrack. Adding to the appeal is the Imperator's stumpy, periscopic rear mirror, sticking out of the roof. Even after being out of production for 20 years, this is still a wild, wild car and we'd happily snap up the opportunity pilot one of the 36 Isderas that were built. Take a look below for the full video from Spa.

Lewis Hamilton wins Spanish Grand Prix, takes 17-point lead over Vettel

BARCELONA, SPAIN – Lewis Hamilton won the Spanish Grand Prix in a commanding Mercedes one-two on Sunday to stretch his Formula One lead over Ferrari's Sebastian Vettel, who finished fourth, to 17 points. The victory, in a race that stayed dry despite the threat of rain, was the Briton's second of the season, 64th of his career and third at the Circuit de Catalunya. It also set a record, one that Hamilton had previously shared with seven times champion Michael Schumacher, of 41 wins from pole position. "This is more like it, let's keep this up," Hamilton told his celebrating team over the radio as he swept past the checkered flag. "Today the car and myself, I felt that synergy which I hadn't been feeling for the whole year," he added in a pre-podium interview after parking up in pit lane. "It's a good feeling." Hamilton's win followed on from the lucky victory that fell into his lap in Azerbaijan two weekends ago, but Sunday had nothing to do with chance and all to do with the champions being back to their best. He now has 95 points to Vettel's 78 after five rounds of the 21-race championship. Mercedes regained the lead in the constructors' standings and are now 27 points clear of Ferrari who had 2007 world champion Kimi Raikkonen retire from the race. Finland's Valtteri Bottas was second, a hefty 20.5 seconds behind, with Dutch 20-year-old Max Verstappen completing the podium for Red Bull – his first of an incident-filled season. Australian Daniel Ricciardo was fifth for Red Bull, ahead of Denmark's Kevin Magnussen for Haas and Spaniards Carlos Sainz (Renault) and Fernando Alonso (eighth for McLaren). Sainz's points lifted Renault ahead of McLaren and into fourth place by a single point. Mexican Sergio Perez was ninth for Force India and Monegasque rookie Charles Leclerc took the final point for Sauber. While Hamilton pulled away cleanly at the start, and Vettel passed Bottas into the first corner for second place, there was carnage behind as Romain Grosjean spun his Haas in a cloud of smoke. The Frenchman then collected the Renault of Nico Hulkenberg and Pierre Gasly's Toro Rosso in a major smash, fortunately without injury, that brought out the safety car for the first six laps. Stewards gave him two penalty points and imposed a three-place grid drop for the next race in Monaco.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
