Mercedes-Benz unveils its revamped G-Class


The all-new G-Class makes its public debut at the Detroit auto show in G550 form. Completely redeveloped and fitted with a 4.0-liter V8 biturbo gasoline engine offering 427ps and 450 lb-ft of torque at 2,000rpm to 4,750rpm, despite near-identical looks to its predecessor plenty has changed for the Mercedes-Benz SUV.

Ford’s F150 pickup gets its first diesel motor


Developed by the powertrain team behind the 6.7-liter Power Stroke engine for super duty trucks, the all-new 3.0-liter V6 Power Stroke unit promises 250ps, 440 lb-ft of torque, and an anticipated 5175kg of towing capacity.

  • Is BMW's all-new quad diesel engine one turbo too many? 
  • As Bentley announces its first diesel engine, is it time for all car makers to embrace state of the art TDI technology?
  • Do hydrogen fuel cells make more sense for commercial and off-road applications than passenger vehicles?
  • Is the disparity between real world and lab-based emissions testing proof that OEMs and engineers should be consulted and more involved by law makers, early in the legislative process? 
  • Are Renault late to a party that's already ended, with the introduction of an all-new diesel hybrid powertrain - co-developed with Continental, or will the mild 48V system kick start this section of the industry??
  • As a US judge approves a US$14.7bn settlement for VW and its diesel emissions scandal, is this a justifiable figure? 
  • Over its 130 year history, which is the most important IC engine development?
  • With the advancement of GDI technology along with BEVs and FCEVs development, are bio-fuel engines and technology finished? 
  • Do hybrids still have a purpose in future mobility, or has the rapid advancement of technologies for both EV and IC applications rendered the 'middle-step' irrelevant, other than for company car tax purposes?
  • With this in mind, will advances in EV technologies force a major rethink in car architecture and packaging?
  • Is the inclusion of cylinder deactivation on Ford's 1.0-liter, three cylinder engine a case of 'technology for technologies sake'?
  • Does diesel have a shelf life in mass-market passenger vehicles beyond nine years?
