Concept Car of the Week: Lancia Bertone Sibilo (1978)

The second half of the ‘70s saw automotive design fall into an era of uninspired and uninspiring economic cars finished with cheap plastic add-ons and stuffed with beige itchy fabrics.

New Mercedes S 63 AMG costs from £119,565

New Mercedes S 63 AMG (pictured) costs from £119,565 The arrival of the new Mercedes S-Class in May saw MB move their range topper on properly for the first time in almost a decade, but with UK prices staring from £62,650 for the S 350 BlueTEC it wasn’t going to be on most people’s shopping list.

To be entirely fair, the new S63 is an awesome car with immense performance (which would be even more impressive if Mercedes endowed it with 4WD, as they do in other markets) with its 5.5 litre bi-turbo V8 developing 577bhp and getting the S63 to 62mph in 4.4 seconds.
