Range Rover’s modern luxury performance flagship, the 635PS mild-hybrid Twin Turbo V8 Range Rover Sport SV, recently proved the stopping performance and durability benefits of its optional Carbon Ceramic Braking system by completing a two-week track driving event at the Algarve International Circuit, on a single set of brake discs and pads.All four of the Range Rover Sport SV EDITION ONEs used on track at the undulating 4.6km Portimão grand prix circuit in Portugal featured the optional Carbon Ceramic Braking system with SV-exclusive Brembo Octyma calipers and 440mm front brake discs, the largest in the automotive industry.On average, each car covered 215 laps of the 15-corner circuit, adding 987km to the 1600 kilometres they had already covered before the event started.When inspected after the drive event, the brake pads for the Carbon Ceramic Braking system still retained around 30 per cent of their usable pad life.Every lap on track included multiple heavy braking zones, particularly into the first right-hand Corner 1 which saw Range Rover Sport SV EDITION ONE slowing from speeds of up to 241kph into the downhill braking zone, generating in excess of 1.1G – a figure it can also exceed in steady-state lateral acceleration during cornering, even on standard-fit all-season tyres.The Carbon Ceramic Braking option also saves 34kg unsprung mass versus the standard Dual-Cast Brakes, which enables even more responsive handling, improved acceleration and enhanced ride quality.
Faced with the explosion of artificial intelligence, which is arousing both enthusiasm and concern, the UN General Assembly adopts its first resolution on this sensitive social issue. The text, prepared by the United States and co-sponsored by dozens of countries, was adopted without a vote, by consensus, after several months of negotiations. IMAGES
Ten years after its launch, the Porsche Macan is heading into its second model generation, now in all-electric form. Through its progressive, timeless design, characteristic Porsche performance, long-distance range and high everyday practicality, the new Macan 4 and the new Macan Turbo aim to completely fulfil the requirements of Porsche customers choosing an SUV. The electric motors draw their energy from a lithium-ion battery in the underbody, with a gross capacity of 100 kWh, of which up to 95 kWh can be actively used. The HV battery is a central component of the newly developed Premium Platform Electric (PPE) with 800-volt architecture, used by Porsche for the first time in the new Macan. The DC charging output is up to 270 kW. The battery can be charged from 10 to 80 per cent within approximately 21 minutes at a suitable fast-charging station. At 400-volt charging stations, a high-voltage switch in the battery enables bank charging by effectively splitting the 800-volt battery into two batteries, each with a rated voltage of 400 volts. This enables particularly efficient charging, without an additional HV booster, at up to 135 kW. AC charging at up to 11 kW is possible at household wall boxes.Up to 240 kW of energy can be recuperated via the electric motors while driving. The Integrated Power Box (IPB) also contributes to the efficiency of the new Macan models, while also saving weight and space. The innovative and compact IPB combines three components – the on-board AC charger, the high-voltage heater and the DC/DC converter. The combined WLTP range is up to 613 km in the Macan 4 and up to 591 km in the Macan Turbo.
International poll observers say Zimbabwe's presidential and legislative elections failed to conform to "regional and international standards", casting doubt on the credibility of a tense vote. The head of the EU observer mission, Fabio Massimo Castaldo, says the election "fell short" on "key principles of equality universality, transparency and accountability". SOUNDBITE
As a premium manufacturer in China, Audi is setting completely new standards with the two partners SAIC and FAW: on the one hand, local development activities are being strengthened, and on the other, drivers are to be offered a dynamic ecosystem around the brand, where customer and brand experience merge into a lifestyle.
The Super SUV Lamborghini Urus’ high-speed record set on the ice of Russia’s Lake Baikal during the Days of Speed in March 2021 has been formally registered by the RAF (Russian Automobile Federation), a member of the FIA (Federation Internationale de l'Automobile). Russian driver Andrey Leontyev, 18-time record holder of Days of Speed on Baikal Ice, shares his experience of setting the record. Reaching a top speed of 298 km/h and an average speed from a standing start of 114 km/h across the 1000-meter distance, the Lamborghini Urus demonstrated exceptional performance and extraordinary handling despite reduced traction due to the ice’s slippery conditions and strong gusts of wind.Andrey Leontyev, Moscow-born and bred, has always had a visceral passion for engines and cars, from disassembling them during his childhood, to reporting on them during his journalism career and driving them during his truck racing years. But his goal and all-time dream was to drive the world’s fastest cars and set records in extreme conditions.
